Delayed-type hypersensitivity to RCM may pose a problem for future radiologic investigations because due to possible immunological cross-reactivity all iodinated RCM are usually avoided.

CT-examinations of 1010 consecutive patients, all examined by 16-row MDCT of the abdomen over a time period of 20 months were retrospectively analyzed. All study patients were examined by triple phase CT (native, arterial and portal venous CT scan) of the abdomen and all received positive oral contrast prior to the examination. Thirty-three patients showed a juxtapapillary duodenal diverticulum, which could be seen on all CT scans, but usually was depicted most clearly on the thin collimated arterial phase CT images. Size of diverticula range from 4 mm to 4.5 cm (mean 1.7 cm). In 17 cases the diverticulum was located ventrally to the vateria...

The clinical presentation is that of a slowly progressive intra-orbital mass with variable degrees of exophthalmos. CT typically demonstrates the presence of a well-defined oval or rounded shaped mass but MRI provides superior evaluation of the orbit. The tumor is intra-conal in 80% of cases and usually shows TlW hypo-intensity, T2W hyperintensity and heterogeneous contrast enhancement that becomes more homogeneous on delayed imaging (5 minutes).

This imaging modality has revolutionized and improved the management and sometimes the treatment of several pathologies, not only in oncology. The main reason for its success is that by PET we can image biological functions instead of anatomy. Consequently, nowadays, PET/CT in joining the morphological and functional imaging has, in many cases, replaced conventional CT as an essential diagnostic medium in managing patients with cancer, neurological diseases, and cardiovascular disorders.

Due to the recent advances in cancer therapy, which include chemoradiation therapy pre- and postoperatively, survival has improved. Radiologist has become an integral part of the patient management team to diagnose and localize the area of recurrent rectal cancer. Although typical pathways of rectal cancer spread have been described, recurrence may occur in unexpected locations due to the currently available aggressive therapy being able to control local disease. Imaging surveillance should include careful evaluation of expected and unexpected anatomic sites where tumor may recur. This paper will describe the common and uncommon locations of recurrent rectal cancer.

They are most frequently associated with tear of the anterior cruciate ligament and/or posterior cruciate ligament. When unrecognized, they may lead to short-term failure of cruciate ligament reconstruction or long-term knee joint degeneration. Early detection of such lesions, especially in the preoperative period, is important since more severe injuries usually require dedicated early surgical management. The anatomy of the posterolateral corner will be reviewed and the normal and abnormal imaging features on MRI and US will be illustrated. The main clinical and surgical features will also be presented.

Ninety-seven patients with a total of 107 breast lesions had mammograms, manual US, and an automated breast US scan. Multiplanar reconstructions in coronal, axial, and sagittal view were reconstructed from the automated dataset and visualized. After biopsy, all lesions were confirmed histologically. The data were evaluated according to the Breast Imaging Reporting and Data System (BIRADS) classification. The sensitivity and specificity were analyzed.

However, a large variety of unusual lesions which are causes of neural foraminal widening can also be encountered in the spinal neural foramen. Radiologic findings can be helpful in differential diagnosis of lesions of spinal neural foramen including neoplastic lesions such as benign/malign peripheral nerve sheath tumors (PNSTs), solitary bone plasmacytoma (SBP), chondroid chordoma, superior sulcus tumor, metastasis, and nonneoplastic lesions such as infectious process (tuberculosis, hydatid cyst), aneurysmal bone cyst (ABC), synovial cyst, traumatic pseudomeningocele, arachnoi...

At times the authors use the technique of the quiz, by presenting a series of radiological findings and asking for the diagnosis, which is often given with a discussion in the facing page. It seems that a book in which the radiological features of a pathology are dealt in its details and in a systemic method, according to the nature of the disease, and the organs involved is becoming rather rare.

The aim of the author is to test the experience of readers, and at the same time if necessary, recommend furthering their radiological knowledge. However, for a more complete evaluation of each neurological pathological disorder, it is recommended that readers consult books in which the imaging and features of the brain are presented in the classic didactic format. This is true in particular for those who are entering the field of neuroradiology.

Hardware innovations, such as the introduction of multi-receiver channel whole-body scanners at 1.5 T and, recently, 3T, combined with acquisition acceleration techniques, have made high-resolution WB-MRI clinically feasible. Now, a dedicated assessment of individual organs with various soft tissue contrast, spatial resolution, and contrast media dynamics can be combined with whole-body anatomic coverage in a multiplanar imaging approach. More flexible protocols, e.g., including T1-weighted TSE- and STIR imaging, dedicated lung imaging, or dynamic contrast-enhanced studies of the abdomen, can be performed within less than 45 min. ...

For pediatric use, the technique is of special interest twofold: first, it is a radiological method without radiation exposure and, second, it allows for whole-body staging as well as for detailed local evaluation for surgical treatment, thus reducing the number of examinations to be performed in sedation. In the pediatric population, the technique is used for oncological and nononcological (i.e., fever of unknown origin, osteonecrosis) staging and for disease severity assessment of syndromes affecting the whole body. These applications will be reviewed and imaging protocols will be presented.

The patient's symptomatology correlated with evolution of diffusion abnormality rather than with lesion enhancement. The lesion demonstrated no hyperperfusion, moderately elevated choline, and decreased N-acetylaspartate.Conventional magnetic resonance (MR) imaging findings of central nervous system Whipple's disease are nonspecific and may mimic neoplasm. MR perfusion and spectroscopy findings are reported, which may assist in diagnosis. Change in diffusion restriction appears to be a potential imaging indicator of clinical progression and response to therapy.

We propose a new dynamic maneuver during flexion-extension of the IP joint. This enables visualization of the adductor aponeurosis and its relationship to the UCL on US allowing detection of a Stener lesion when it exists. All patients with Stener lesion on US underwent surgery (32 operated patients): the sensitivity of US was 95.4% with a specificity of 80% for detection of Stener lesions. US, with the use of this specific dynamic maneuver is a reliable and reproducible tool for detecting Stener lesions.

MDCT imaging findings needs to be evaluated considering the clinical history and symptoms and other abdominal findings that could be of help in differential diagnosis. Several protocols have been suggested and indicated in the imaging of patient with acute intestine. However, a CT protocol in which the precontrast scanning of the abdomen is followed by i.v. administration of contrast medium using the 45–55 s delay could be effective for an optimal visualization of the bowel wall. It is important to learn to recognize how the intestine reacts to the injury and how it “talks”, in order to become aware of the different p...

An ill-defined mass with peripheral infiltration was recognized on a chest radiograph. Thoracic computed tomography showed an intrabronchial mass lesion at the proximal portion of the bronchial bifurcation of the right B1 segment. The tumor completely occluded the bronchial lumen and thus caused obstructive changes of the lung distal to the tumor.

The incidence of increased FDG uptake is 0.1% in all 2193 women, 0.5% in women with uterine leiomyoma, and 3.4% in women with degenerated leiomyoma. There was no relationship between the intensity of FDG uptake and the size/site of leiomyoma or the tendency of degeneration in leiomyoma. The women with the increased uptake were not limited at premenopause.

Twenty-four patients (15–59 years old; mean and median age 36 years; 7 males; 17 females) with genetically proven NF1 were examined with whole body MR imaging. Axial and coronal T1- and fat-suppressed T2-weighted images (slice thickness 6-12 mm) were acquired on a 1.5-T MR unit (Symphony; Siemens, Erlangen, Germany). The images were reviewed by two radiologists: one senior, one junior. The criterion for a neurofibroma was a mass lesion with low signal intensity on T1 and high signal intensity on T2, along the course of a nerve.

Velocimetry in malignant breast lesions and density of malignant vessels are very low. In breast imaging, first results of contrast-enhanced ultrasound were disappointing. Microbubbles are fragile when examined with high frequency US, commonly used in breast imaging. Second-generation contrast agents increase intensively the signal level of breast lesions and new sequences like coherence pulse sequencing might be accurate to detect malignant vessels in breast lesions for characterization, to assess the extent of infiltrative breast carcinoma or to evaluate the tumor response after chemotherapy. Another interesting clinical application is the differentiation between post-operative changes and recurrences.

Following admission to the emergency department, a 64-slice cardiac computed tomography (CT) revealed a Stanford Type A aortic dissection arising from a previous coarctation repair. Multiphasic reconstructions demonstrated an unstable, highly mobile aortic dissection flap that extended proximally to involve the right coronary artery ostium. Our case is an example of the application of electrocardiogram-gated cardiac CT in directly visualizing involvement of the coronary ostia in acute aortic dissection, which may influence surgical management.

Thus, there is a better potential for identifying pathophysiological processes at an earlier stage or of a different character than even a trained radiologist can find. In the present study, the potential of texture analysis for in vivo identification of the administering effect of an anti-inflammatory drug in cerebral stroke in rats was evaluated.Twenty-seven Wistar rats underwent middle cerebral artery occlusion resulting in local ischemic brain infarct. One group of rats received alpha-melanocyte stimulating hormone (α-MSH) and a control group received saline only. T2-weighted images, apparent diffusion maps, and ...
