At MRI, ameloblastoma has mixed signal inten-sity on T1- and T2-weighted images: typically Benign lesions: Hemangioma: Cystic mass (arrowheads) w/wo internal trabeculation (arrows). Smaller hemangiomas may be echogenic: Hypo-attenuating lesion on non-contrast enhanced images, w/wo calcifications. Progressive enhancement is characteristic. Delayed images demonstrate a nearly isoattenuating mass, w/wo calcification 2015-05-05 Both kidneys are markedly enlarged and heterogeneous with multiple fat-attenuating parenchymal lesions. These lesions are compatible with hepatic and renal angiomyolipomas. Within the right kidney is a large predominantly hypoattenuating mass with a prominent and tortuous vessel traversing within it.

attenuation A generic term for a reduction or diminution of activity, intensity, power, or virulence of a reaction, effect, or organisms ability to grow and/or multiply Microbiology ↓ virulence of a microorganism–eg, that of bacillus Calmette-Guerin–BCG, a strain of Mycobacterium bovis that has been weakened by multiple–238–subcultures on a bile-glycerine medium; the resulting This type of lesion contains a clear, bile-like liquid and does not usually cause any symptoms. Although, in rare cases, if the cyst is large, it may cause abdominal pain or nausea, vomiting, and early satiety. Anywhere from 2.5% to 18% of the general population could have benign cysts in their liver. 3. Eventually the lesion will become iso-attenuating to the liver, but only because the vessels become iso-attenuating with the liver. It has nothing to do with the density of the liver parenchyma itself.
Some FNH lesions will take up as much SPIO as normal liver, so the lesion appears black on the post-contrast T2w images. In other cases the lesion may take up some SPIO, but less than the surrounding liver, so that the lesion becomes more apparent after contrast. RADIOGRAPHIC FEATURES CT SCAN Hypo to iso dense lesions are seen with edema and necrosis appearing as a low attenuating area on CT scan.
