Some of these tumors may demonstrate typical imaging features. However, due to the rarity of these tumors, imaging characteristics of these diverse lesions are not well described in the literature. Knowledge of these select ovarian entities is essential and facilitates optimal management of patients who often manifest with nonspecific symptoms.

The specific signature of macroscopic fat on computed tomography along with the usually characteristic findings of these entities makes the diagnosis of most of these conditions relatively straightforward. In the intestinal tract, the “fat halo sign” usually arises in the context of subacute to chronic bowel wall inflammation. Excess fat in the renal sinus may occur with renal sinus lipomatosis or “replacement lipomatosis of the kidney.” Some cases of “pancreatic lipomatosis” may culminate in steatopancreatitis and ultimately neoplastic transformations. “Fibrofatty mesenteric proliferation” is a characteristic feature of Crohn disease.

Despite certain inherent limitations in evaluating chronic liver disease on routine gray-scale US, it is still widely used for the initial evaluation in patients suspected of liver disease as well as for hepatocellular carcinoma (HCC) screening in patients with known cirrhosis. Due to recent advances in digital technology and US imaging software, various new computer protocols have been incorporated in the new US equipment. This in turn has resulted in a great improvement in image quality and image resolution. Consequently, the increased ability of US to better characterize the liver texture in general has enabled the sonographers to identify subtle changes in the liver texture and delineate smaller masses in the liv...

It helps in nourishment of articular structures. The synovium is affected by a variety of disorders that can be either localized or systemic. Although normal synovium is barely perceptible on magnetic resonance imaging, it provides an excellent imaging modality for the evaluation of pathologic processes involving the synovium. The pathologic processes affecting the synovium include 1 of the following etiologies: inflammatory, infectious, degenerative, traumatic, or neoplastic and tumor-like conditions. In this article, we discuss the magnetic resonance imaging technique and the sequences used in the evaluation of synovial pathologies and review the characteristic imaging find...

Although most children with seizures do not require imaging, when indicated, imaging plays an important role in the clinical workup. Imaging in the pediatric seizure population is reserved for a particular subset of patients depending on factors, such as age of onset, symptomatology, physical examination findings, and specific electroencephalography changes to name a few. The etiologies of seizures are extensive and include disorders of cortical migration and organization. Cortical migration and organization disorders are multifactorial and complex and a major cause of seizure disorders. Although magnetic resonance imaging is the most common imaging modality used to identify the seizure focus, pos...

Ultrasound is the initial imaging investigation of choice when gestational trophoblastic disease is suspected. Complete hydatiform mole, the most common form of molar pregnancy, usually has a characteristic “cluster of grapes” appearance, especially on second-trimester ultrasounds. Persistent trophobastic neoplasia usually appears as a focal, hypervascular myometrial mass on pelvic ultrasound. Pelvic magnetic resonance imaging is often used as a problem-solving tool in equivocal or complicated cases of gestational trophoblastic disease to assess the degree of invasion into the myometrium ...

Traditional cardiovascular disease risk factors as well as aspects of HIV infection and its therapy contribute to the increased coronary artery disease observed in HIV. Advances in noninvasive imaging methodologies in both computed tomography and magnetic resonance imaging provide opportunities to evaluate coronary artery atherosclerosis in ways not possible by conventional invasive x-ray angiography. Application of these techniques may prove very useful in the study of atherosclerosis in many diseases, such as HIV.

This condition affects women during their reproductive years. Ovaries are by far the commonest location of endometriosis and have peculiar imaging features. However, the imaging diagnosis of extraovarian endometriosis is difficult to make both clinically and radiologically. The purpose of this article is to review the imaging features of endometriosis at typical and atypical sites on different modalities and to describe the commonly encountered complications. Atypical sites for endometriosis include the gastrointestinal tract, urinary tract, soft tissues, and chest. Depending on the site, they can present with varied symptoms, including bowel obstruction, m...

CO2 may serve as a suitable alternative intravascular contrast agent in these patients with arteriographic applications, including evaluation of peripheral vascular disease, and venographic applications, such as transjugular intrahepatic portosystemic shunt procedure, to name a few. Unique properties of CO2, such as low viscosity, lack of an allergic reaction, and renal toxicity, have afforded it its diagnostic capabilities. However, certain properties of CO2 also pose a technical challenge in terms of its delivery. Although it remains a relatively safe alternative contrast agent, potential adverse effects have been reported and exist. (Source: Current Problems in Diagnostic Rad...

Depending on the site of recurrent bleeding, musculoskeletal manifestation can be in the form of hemophilic arthropathy and/or soft tissue, intraosseous, or subperiosteal pseudotumors. Radiography, sonography, computed tomography, and especially magnetic resonance imaging help in the evaluation of hemophilic arthropathy and pseudotumors, providing accurate diagnosis, thus avoiding inadvertent procedures and related complications. Treatment includes replacement of clotting factors either continuously or when indicated, radionuclide or open synovectomy in cases of disabling arthropathy.

Congenital fetal diaphragmatic hernias, traumatic diaphragmatic rupture, and large symptomatic Bochdalek, Morgagni, and hiatal hernias are typically repaired surgically, while eventration, diaphragmatic slips, and small diaphragmatic hernias do not require intervention or imaging follow-up but should be recognized to avoid confusion with other diagnoses that require additional attention. This pictorial essay will explore the imaging findings and clinical characteristics of these entities.

Bubbly lucent lesions of bone are recalled with the FEGNOMASHIC mnemonic, but when only lucent lesions of the diaphysis are included, a more appropriate mnemonic is FEMALE. The lucent lesions of bone differentials often can be narrowed based on specific characteristics of the lesion but radiographic findings elsewhere and clinical information often help. Osseous metastases may present as lucent or sclerotic lesions; when sclerotic, the differential is best remembered with the mnemonic 5 “BEES” Like Pollen. The mnemonic for Wormian bones is PORKCHOPS.

The commonest pathologic entities are divided into the 4 following groups: torsion, trauma, infection, and tumors. Sonographic examination should be performed as soon as possible to ensure fast diagnosis and treatment. Less acute conditions can also be noted while scanning on an emergency basis, such as anatomic variants, hydrocele, oscheocele, clinically evident varicocele, calcifications, etc. Although not threatening for scrotal integrity, they should be assessed during an emergency examination or later on. In this article, complex scrotal anatomy is reviewed and the basic examination technique is described. The commonest emergency conditions are analyzed, along with their pathophysiological...

Routine CT colonography imaging of the insufflated colon was performed in both the supine and the prone positions with oral contrast. 3D reconstructed images were then obtained using Viatronix software and were interpreted along with the axial images. Each patient was classified into groups based on the quality/adequacy of the examination, presence, number, and size of polyps. The patients were also evaluated for any diverticula, benign lesions such as lipoma, stricture, or mass. In addition to its use as a primary screening tool, CT colonography can be used as an adjunct to optical colonoscopy as in our institution. A cooperative use of both screening mod...

Interstitial lung disease (ILD) is the most common manifestation of rheumatoid lung disease. The ILDs associated with RA are diverse and it is very important for the general radiologist to differentiate one from another. There are many other pulmonary diseases apart from ILD. These are associated with a wide spectrum of morphologic changes with substantially different prognoses. The diagnosis of most of these diseases is by clinicoradiological correlation and some of them need pathologic correlation. High-resolution computed tomography helps to characterize and determine the extent of ILD in RA. When interpreting the high-resolution computed tomography of the chest in RA, the...

Common indications for spinal cord stimulation include chronic neuropathic and oncological pain, intractable angina, or chronic pain secondary to vascular disease. It is estimated that up to 4 million patients may be candidates for the therapy. Therefore, it is likely that an increasing number of patients will have spinal neurostimulation devices implanted over the coming years. Because radiography and computed tomography are the primary imaging modalities used to evaluate the proper positioning of these devices, radiologists should be familiar with their appearance. The purpose of this article is to discuss the types of neurostimulation devices currently being used and to demonstrate their respective imaging appearan...

Data from a single CT acquisition can be reconstructed into image series that would formerly have required multiple acquisitions. Small isotropic voxels permit scan parameters to be general while reconstruction algorithms remain specific to anatomy. While this results in more efficient operation in the Emergency Department, it necessitates new ways of displaying, interpreting, and archiving the information. Critical decisions include how much of the patient to scan and how to time contrast injections when imaging multiple organs. These choices must be made in light of dose considerations to the patient and the gene...

To maximize the identification of ultrasound and mammographic correlates to MRI-identified lesions, one must carefully review the initial MRI examination as well as be cognizant of breast normal anatomy and variations in breast position across imaging modalities. We review the steps required for planification and realization of a successful second-look evaluation.

Radiologists may be the first to suggest the diagnosis of CN and can facilitate prompt intervention and treatment if they are aware of the radiographic manifestations of CN and the signs of progression of disease. Radiologists should also become aware of the evolving treatment of the disease as focus is shifting toward early surgical intervention and limb salvage rather than amputation. Knowledge of preoperative assessment, the types of surgeries performed, and some of the encountered postoperative complications enable the radiologist to facilitate timely intervention by our surgical colleagues and be a valuable member of the management team.

Cardiac structures can now be quickly evaluated with exquisite detail in a noninvasive manner. Cardiac CT is increasingly being used for the noninvasive evaluation of coronary arteries, procedural planning, and evaluating chest pain in certain clinical situations. Dual-source CT is a recent technological development that has helped improve spatial and temporal resolution for cardiac CT imaging. It is one of many “next generation” CT technologies that are now pushing image quality to new levels. The interpreting radiologist must now be familiar with detailed cardiac anatomy that is routinely imaged with these next generation units. Understanding normal cardiac anat...

High-resolution US allows recognition of small, clinically occult melanomatous foci within the skin and lymph nodes. Consequently, it plays a major role in locoregional staging and follow-up of patients with cutaneous melanoma. We discuss the possibilities and limitations of US in the initial staging (primary melanoma, satellite metastasis, in-transit metastasis, and lymphadenopathy), selection for sentinel lymph node biopsy procedure, patient follow-up, detection of recurrence, and US-guided intervention.

Occasionally, on MDCT studies, dense linear branching opacities may be found within the pulmonary vessels. They represent dense emboli within the pulmonary arteries (DEPA). These may occur in oncologic patients that undergo specific treatments or interventional procedures, such as cement embolus from vertebroplasty, catheter or coil migration after embolization procedures, radioactive seed embolus in patients treated with local brachytherapy for prostate, lung, or liver cancer, and also in chronic pulmonary embolism. Usually DEPA does not have any clinical significance but may be fatal when massive or when in patients with impaired cardiopulmonary function...

Any of these joints can dislocate. Dislocations are uncommon, tend to spontaneously reduce, and can be difficult to detect on clinical examination. There are, however, telltale imaging features and the radiologist may be the first to suggest the correct diagnosis. A timely diagnosis is important as some forms are associated with limb-threatening complications. Lateral patellofemoral dislocation, in the acute setting, is typically an injury of young athletes and usually spontaneously reduces at the time of trauma. In transient lateral dislocation, contusions may be seen in the inferomedial pole of the patella and the anterior lateral aspect of the nonarticular portion of the ...

Even without electrocardiogram gating, MDCT provides accurate information about the heart. In the group of oncologic patients, different tumoral and non-tumoral-related heart disorders can be found, for example, metastatic cardiac involvement (approximately 10% of patients with lung or breast cancer will develop metastases to the heart), paraneoplastic cardiac disorders, non-tumor-related heart disorders, and chemotherapy- and radiotherapy-related cardiac side effects.

HSG demonstrates the morphology of the uterine cavity, the lumina, and the patency of the fallopian tubes. In this review article, we present the technical parameters of the examination, indications, contraindications, and possible complications of HSG. We also illustrate a variety of abnormalities of the uterus and fallopian tubes that can be detected accurately with HSG. We believe that, with the increased demand for HSG, radiologists should be familiar with HSG technique and the interpretation of HSG images.

A pseudoaneurysm can involve any vascular bed and is usually associated with direct arterial injury or erosion of an artery by an adjacent tumor or inflammation. In this article, we discuss different clinical settings and various imaging modalities such as ultrasound, computerized tomography, magnetic resonance imaging, as well as conventional angiography used for the diagnosis of pseudoaneurysms. We also describe the role of newer endovascular, percutaneous, and traditional surgical approaches for the treatment of visceral and peripheral pseudoaneurysms in different clinical circumstances.

Normal physiology can explain many regions of increased FDG activity, as well as incidental benign tumors and benign metabolic conditions. Recognition of characterization of benign causes and physiologic variants for FDG uptake are discussed to avoid improper characterization as a malignancy. A basic understanding of PET/computed tomographic physics is also discussed, in relation to attenuation correction artifacts caused by metallic implants and contrast agents in the gastrointestinal tract, as well as artifacts caused in fused images due to patient motion....

Advances in transplantation, oncology, and the treatment of AIDS have extended these patients' life expectancies and thereby increased the immunocompromised population. Classical clinical signs of abdominal sepsis may be absent in the immunocompromised host. Consequently, the radiologist is increasingly called on to diagnose specific acute intra-abdominal complications associated with immunodeficiency. This review describes the etiology of the acute abdomen in this heterogeneous group of immunocompromised patients, causes including opportunistic infections, neutropenic ...

Doppler ultrasound has an advantage over computed tomography or other imaging modalities in that it is noninvasive, can be used intraoperatively or immediately postoperatively at the patient's bedside, and is free from radiation hazard. Doppler ultrasound is also sensitive to very slow flow and is not limited by an optimal temporal window because it is a real-time examination. However, this examination is highly operator-dependent. For a proper evaluation of patient hemodynamic status, optimization of Doppler parameters and liberal use of spectral analysis will help prevent m...

The other 20% of pancreatic tumors is represented by a heterogeneous group of pancreatic neoplasms that includes cystic pancreatic neoplasms, islet cell tumors, and the so-called rare pancreatic tumors. In addition, the pancreatic gland may present a variety of inflammatory and pseudotumoral lesions that may mimic a primary pancreatic neoplasm. These uncommon tumors and pseudotumoral lesions present a wide spectrum of imaging findings and they are often poorly understood by the radiologist, becoming a diagnostic challenge.

In addition to favorable polyp detection capabilities, OC has a unique therapeutic role with the ability to remove identified polyps. However, this procedure carries a low but real risk for morbidity and mortality. OC requires physical intubation of the length of the colon and manipulation of the instrument. In addition, the performance of therapeutic polyp removal increases risk. Inherent to this procedure are several pathways for potential adverse events. Complications can be divided into several major categories including perforation, hemorrhage, postpolypectomy syndromes, and issues related to sedation.

Although the clinical diagnosis can be made accurately in typical cases, imaging plays an important role in improving diagnostic accuracy of this condition, especially when the clinical diagnosis is uncertain. Magnetic resonance imaging is an emerging promising technique for the diagnosis of acute appendicitis, especially in patients with nondiagnostic ultrasound and in patients where radiation is a clinical concern. In the following review, the role of magnetic resonance in the diagnosis of appendicitis will be discussed.

Based on imaging evaluation, the complications of renal transplantation can be divided into four major categories: peri-renal, renal parenchymal, renal collecting system, and renal vascular complications. Common complications included acute tubular necrosis, graft rejection, drug nephrotoxicity, hematoma, lymphocele, urinoma, hydronephrosis, and vascular complications. Ultrasound has a key role in identification and management of most of these complications. However, some parenchymal complications may only be diagnosed on renal biopsy. Ultrasound is a very powerful screening tool to assess renal transplant dysfunction and has a primary role in early diagnosis and ...

Displaced meniscal tears including free meniscal fragments are an important diagnosis as most of these tears are unstable and require surgical intervention. Magnetic resonance imaging can be an invaluable tool in the arthroscopic search for a free meniscal fragment. In addition to the commonly seen bucket-handle tears flipped into the intercondylar notch, it is important to be aware of less common locations where menisci may be displaced.

Injury to the C1/C2 complex accounts for 19 to 25% of cervical spine injuries. Fractures of C2 occur most frequently, 55% of which involve the odontoid peg. The unique anatomical relationship between the atlas and axis produces a variety of injury patterns not seen elsewhere in the spine. Numerous developmental anomalies also occur which can mimic trauma. Well-described fracture patterns include posterior arch fractures of the atlas, Jefferson type fractures, fractures of the odontoid process, and Hangman's fractures. Traumatic subluxation of C1 on C2 and rotatory fixation also occur with or without associated bone injury. Computed tomography ...

In this article, we illustrate and discuss MRI techniques and findings of the most commonly seen renal anomalies, including congenital, inflammatory, neoplastic, posttransplant, and miscellaneous conditions.

Not only do they represent a significant proportion of the radiological workload arising from emergency rooms, interpretation of the images acquired is often difficult due to the complex anatomy of this region, compounded by an inability to obtain adequate views due to patient discomfort. Often, despite apparently normal radiological examinations, patient discomfort persists, prompting a need for further imaging. It is vital that the radiologist be entirely familiar with the bony and ligamentous anatomy of this body region, as well as possess an understanding of the fre...

First the relationships between computed tomography dose index, dose length product, and effective dose in adult and pediatric CT are revised, along with the diagnostic reference level concept. Then the effect of image noise as a function of volume computed tomography dose index, reconstructed slice thickness, and the size of the patient are described. Finally, the potential of tube current modulation CT is discussed. PMID: 17601537 [PubMed - in process] (Source: Current Problems in...
