Breast MR imaging is a slightly more sensitive modality than mammography but not a highly specific technique for evaluating breast lesions. It has utility in several clinical situations but should not be used as a substitute for biopsy or general screening.
Littoral cell angioma is an uncommon primary vascular neoplasm of the spleen. It frequently follows a benign course, but cases with aggressive behavior have been described. We present a case of this rare disease highlighting radiological examinations showing a rapid increase in the size of the spleen as well as an increase in the number and size of existing nodules. We also discuss the relationship of this disorder to chronic infections and its possible association with Epstein Barr virus.
A pulse Doppler device linked to a commercially available B-mode ultrasound scanner permits the origin of the Doppler signals to be located accurately on the B-scan by a bright-up cursor. Case histories illustrate the clinical application of this device in differentiating between vascular and nonvascular structures, or patent and thrombosed vessels. This is especially valuable when there is pathological distortion of the anatomy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
