Artificial multiple sclerosis lesions on simulated FLAIR brain MR images: echo time and observer performance in detection.

abstract：:While computed tomography (CT) is an accepted procedure for investigation of the inferior vena cava (IVC), little attention has been given to its use in IVC thrombosis secondary to proximal extension of thrombi within the lower venous system. Four cases are presented and several advantages of CT over standard contrast...
