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

Q image thumb

spleen is hyperintense to the liver

spleen is mottled or marbled enhancement

only the cortex of the kidneys is enhanced

60

figure B 28 shows images during various phases of contrast enhancement.  Most oliver cancers are "arterially" fed and therefore are visualized on

Q image thumb

first pass images

61

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

Q image thumb

delayed images

62

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
