spleen
due to its size and orientation with in the body, the entire pancreas can possibly be visualized on one imaging sectoin if it is acquired
obliquely with thick sections
on T2 weighted MR images, hemangiomas of the liver appear
hyperintense to the normal liver

figure B 28 shows images during various phases of a contrast enhancement including early (arterial-first pass), intermediate (cortico-venous phase-second pass) and delayed phases (third pass). Arterial phase imaging demonstrates all of the following
spleen is hyperintense to the liver
spleen is mottled or marbled enhancement
only the cortex of the kidneys is enhanced
figure B 28 shows images during various phases of contrast enhancement. Most oliver cancers are “arterially” fed and therefore are visualized on
first pass images
figure B 28 show images during various phases of contrast enhancement, Hemangiomas are “benign” lesions (typically watch and wait lesions) that are venous fed, and therefore are visualized on
delayed images
patient positioning for abdominal MR images includes all of the followoing positions
supine, head first within torso array coil
supine feet first with in torso array coil
prone feet first within the torso array coil
