The majority of FNH tend to remain static in size, although FNH may increase in size on follow-up (311%), although oral contraceptives do not appear to stimulate FNH growth [38, 39]. Mol. FNH is isodense or minimally hypodense on unenhanced and equilibrium-phase post-contrast CT and may be only suspected because of the presence of mass effect on adjacent vessels. PubMed Radiographics.

These are common everyday type findings that (ac) T1-weighted dynamic enhanced T1-weighted GRE in the (a) arterial and (b) portal venous and (c) delayed phase shows nodular peripheral enhancement of the lesion with centripetal filling. (b) Gadoxetic acid-enhanced image shows strong enhancement in the arterial phase. Small lesions (up to ~2 cm) may show immediate and complete enhancement in the arterial phase, with sustained enhancement in the venous and delayed phases (type I, flash filling) [31] (Fig. Among these 60 patients, 43 (71.7%) had solitary indeterminate nodules, 36 (60%) had synchronous lesions, and 24 (40%) had metachronous CRLM. Hepatocellular carcinoma: imaging patterns on gadoxetic acid-enhanced MR images and their value as an imaging biomarker. In general, HCC is considered in a setting of cirrhosis or chronic liver disease. 2016;26:4595615. 2011;261:17281.
