MSCT angio advances in peripheral vesselsCT angiography is an emerging technique for noninvasive evaluation of peripheral vascular disease. CT was first used to evaluate the peripheral vasculature in the early 1990s. Single-detector spiral CT scanners were limited by their inability to cover the whole vasculature from the diaphragm to the feet quickly enough to track a contrast bolus. These limitations were overcome with the advent of multislice CT scanners in 1998.1 MSCT images are comparable to those obtained with catheter angiography.

Small bowel findings reveal tumor spectrumThe spectrum of usual and unusual primary neoplasms involving the duodenum, jejunum, and ileum is extremely wide. Our own database of digestive pathology contains a range of benign small bowel neoplasms (adenoma, leiomyoma, lipoma, familial polyposis, hemangioma, lymphangioma, and fibroma), as well as examples of malignancy (adenocarcinoma, carcinoid tumor, lymphoma, leiomyosarcoma, direct extension from extraintestinal tumors, and metastasic lesions).

Ultrasound seeks out metastatic melanomaCutaneous malignant melanoma is a relatively common malignancy, and its incidence is increasing worldwide, especially in the Caucasian population. The clinical course of melanoma depends on tumor thickness, localization, ulceration, growth rate, and histology of the primary tumor. Metastatic spread may arise from very small masses.

MR imaging evaluates ulcerative colitis casesAdvances in MR technology have improved the quality of abdominal MRI and hence the ability to assess intestinal diseases. Rapid acquisition sequences have reduced the incidence of motion artifacts from intestinal peristalsis, while the use of phased-array coils has increased spatial resolution. Several intestinal contrast agents have undergone extensive trials. Meanwhile, the use of sequences that modulate MRI signal selectively, for example by suppressing fat tissue signal, can improve gadolinium-related enhancement on T1-weighted images, as well as boosting T2 signal in pathologic tissues.

Carotid stenting offers new interventional practice optionAs carotid artery stenting becomes an accepted tool for stroke prevention in appropriate patients, interventional radiologists and neuroradiologists are determining where this procedure fits into their practice. Some have already developed an active carotid artery stenting practice, but others are looking for resources to help them begin to offer this service. Consideration of many elements is required to offer a high-quality service.
