Imaging of Nontraumatic Hemorrhagic Hepatic Lesions

Acute nontraumatic liver lesions.

The principal conditions requiring emergency/urgent intervention in patients with nontraumatic liver lesions are hemorrhage (with or without tumor rupture), rupture of hydatid cysts (with or without infection), complications arising from liver abscesses or congenital liver cysts, rupture related to peliosis hepatis, and in rare cases spontaneous hemorrhage. This article examines each of these c...

Bone imaging demonstration of osseous lesions and hepatic uptake: Amyloid and renal dialysis effect

A 64-year-old woman, with amyloid related kidney failure (On renal dialysis) had a bone scan because of pain in the right upper femur. The 99m Tc-MDP images revealed marked hepatic uptake. In addition, there was right proximal femoral concentration of radiotracer, which corresponded to a fracture site. As an added finding, the same femor demonstrated circumferential uptake at the lower po...

SSFSE MR Imaging of Focal Hepatic Lesions

With improvements in pulse sequence design and gradient amplifiers complete breath-hold MR imaging of the liver is possible enabling rapid evaluation, which is relatively free of motion artifacts. The combination of Single Shot Fast Spin-Echo (SSFSE) and Fast Multiplanar Spoiled Gradient-Echo(FMSPGR) sequences provide both breath-hold T2and TI-weighted non-contrast images, as well as multiphase...

NEURO IMAGING OF CNS LESIONS IN AIDS

Background: The aim of this study was to review and characterize the pattern of CNS lesions in patients suffering from AIDS and to correlate these patterns with clinical disorders. Method: The MR scan, medical records and laboratory findings of 58 AIDS patients were reviewed retrospectively during April 1994 to November 1997 at the Olive view/UCLA and Shiraz Medical Centers, and the patterns o...
