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.

In most of the cases the proper analysis of MRI findings in correlation with the patient's history is sufficient to meet a specific diagnosis. However, diagnostic confusion is not uncommon as there are numerous lesions affecting the hand and wrist region. This pictorial essay offers a practical radiological approach to benign tumors and tumor-like lesions of the hand and wrist region based on most frequently observed MRI findings.

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. MDCT plays a role in the detection of these entities. We show the non-electroca...

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...

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.

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.

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.

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.

We radiologists therefore need to know the appropriate indications for performing breast MRI and understand the MRI features of breast disease. We herein review and discuss the application of current pulse sequences and the imaging strategies for MRI of breast pathologies. We will illustrate the MRI features of various breast pathologies including malignant tumors such as invasive and noninvasive ductal carcinoma, special types of invasive carcinoma (mucinous, apocrine, lobular carcinom...

The primary role of computed tomography (CT) in bladder cancer is for tumor staging and screening for distant metastases. Multidetector-row CT may improve the evaluation of bladder tumors by overcoming the difficulties of previous generations of CT in detecting invasion of contiguous organs and nodal staging. Magnetic resonance imaging (MRI) however is still considered superior to CT for primary staging of bladder carcinoma. The multiplanar capability of MRI with its superior soft-tissue resolution offers improved evaluation of local staging of bl...

For example, abdominal pain after a colonoscopy may vary in etiology and can result from simple colonic spasm to colonic perforation, hemoperitoneum, or even splenic rupture. Vague abdominal pain following a renal biopsy may be due to minimal postprocedural bleeding into and around the kidney or may be due to potentially life-threatening hemorrhage.

It can be caused by a primary leiomyosarcoma originating in the vessel wall or by intraluminal extension of tumor thrombus into the IVC from an adjacent organ. We reviewed 21 cases of tumoral thrombus in the IVC including primary leiomyosarcoma of the IVC (2 cases), renal cell carcinoma (14 cases), adrenocortical carcinoma (2 cases), primary adrenocortical leiomyosarcoma (1 case), hepatocellular carcinoma (1 case), and retroperitoneal metastasis (1 case).

CT can confirm the presence of SBO; show the site, level, and cause of obstruction accurately; and detect strangulation. It is important to recognize the common and unusual causes, but also conditions that mimic SBO. This review illustrates a spectrum of causes and discusses conditions that mimic SBO and their differentiation and the limitations of CT in the assessment of suspected SBO.

The advent of multi-detector row CT (MDCT) has resulted in rapid acquisition times and improved z-axis resolution that paved the way for CT angiography. With MDCT technology, CT angiography has become more dependent upon optimal vessel opacification and, consequently, contrast administration protocols have had to evolve. We examine the use of intravenous contrast from a historical perspective and discuss the latest methodologies, such as saline chasing techniques, that optimize the contrast bolus with CT angiography.

The differential diagnosis of the acute scrotum can be divided into four categories-torsion, trauma, tumor, and "testiculitis" (epididymo-orchitis). Although testicular neoplasms are not imaged emergently, 15% are detected incidentally when performing an emergent scrotal ultrasound. Therefore, the emergent sonographic examination of the testicles should include a thorough search for malignancy. Images demonstrating the sonographic and color Doppler appearances of each of the "four T's" will be reviewed. The radiographic review will focus on the imaging features, which are the keys to arriving at the correct diagnosis. PMID: 16399236 [PubMed - indexed for MEDLINE] (Sou...

In addition to the evaluation of the trauma patient where CT is essential when imaging complex skeletal injuries, MDCT is particularly useful in patients who have had prior surgery. In postoperative cases, metal artifact typically prohibits magnetic resonance imaging evaluation, but volume-rendering of a MDCT axial database virtually eliminates streak artifact associated with hardware. For the evaluation of masses, CT provides the ability to detect and characterize calcification, cortical disruption, and periosteal reaction.

The decision to attempt a curative surgery or avoid an unnecessary surgery is dependent on accurate staging. In the case of non-small-cell lung cancer (NSCLC), the most important parameters for optimal treatment and prognosis are the presence of cancer spread to the lymph nodes within the mediastinum and to distant organs. Endoscopic ultrasound (EUS) has become an important tool for the assessment of mediastinal lymph nodes and in some cases, distant organ metastases, because of its minimally invasive access to these sites through a transesophageal, transgastric, or transduodenal approach.

Usually asymptomatic, they are relatively common in our population. They can present in several different locations, which can have an impact on the clinical presentation and the degree of dysfunction. Occasionally, these can become symptomatic, which can manifest as chronic or acute on chronic foot pain. Diagnosis of this condition relies on radiographic evaluation. The 45-degree eversion oblique view of the foot is the most important view for identifying this condition, although several different imaging techniques can be used. Treatment of this condition includes both surgical and nonsurgical options. Ultimately, surgery yields the best outcome for youn...

The most common form of CVI is primary varicose veins due to the insufficiency of the saphenous system. Color-Doppler sonography (CDS) is actually the main diagnostic technique of imaging for CVI. In this article, we describe the anatomy, the technique, and the information necessary to the radiologist to perform CDS in chronic venous insufficiency. The knowledge of the venous anatomy is the cornerstone for an adequate sonographic examination. ...

Thickening of the peribronchovascular interstitium can be seen in a wide variety of diseases. The CT appearance can be smooth, nodular, or irregular depending on the underlying cause. Many of the diseases affecting the peribronchovascular interstitium are entities that show a predilection for lymphatic routes, such as sarcoidosis, pulmonary lymphangitic carcinomatosis, silicosis, and lymphoproliferative disorders. There are other entities that mainly affect the peribronchovascular interst...

Although echocardiography establishes the diagnosis in most cases, CT and MRI provide additional physical, spatial, and functional information that further aids the evaluation of metastases. For instance, CT provides superior resolution for detecting calcification or fat, while MRI with its direct multiplanar ability more completely characterizes the heart, pericardium, mediastinum, and lungs. MRI also helps elucidate the pathophysiological effects of these tumors on cardiac function through gated cine-loop sequences. Beyond tumor characterization, both modaliti...

Although rare, benign tumors outnumber their primary malignant counterparts three to one. Since mortality varies directly with invasion, identifying the neoplasm at an early stage helps focus treatment, especially in benign cases, which generally respond well to surgical resection. In adults and children, myxomas and rhabdomyomas, respectively, represent the most common benign tumors, which can be grouped into tissue-specific subtypes, such as rhabdomyomas, fibromas, lipomas, teratomas, etc. Besides their variable prevalence in particular age groups, these tumors also differ with regard to their gen...

Almost 50% of all mediastinal masses are located in the anterior mediastinum. The thymus is the most common site of origin of these masses. Several kinds of lesions can arise from this gland because it derives from the three embryonic germ cell layers. Primary neoplasms of the thymus are thymoma, thymolipomas, carcinoma, carcinoid, primary germ cell tumors, and lymphoma. The latter can also involve the organ in a secondary fashion. Other lesions that cause thymic enlargement and that can be confused with neoplasia are thymic cysts and thymic hyperplasia. Even though anteri...

Discriminating between the various lesions requires an understanding of the underlying pathophysiology and imaging characteristics that lead to their malignant appearances. A pattern approach of recognition by imaging with understanding of why particular lesions behave the way they do on sonography, CT, MRI, and nuclear scintigraphy can be developed.
