Objective: To differentiate hyperintense hepatocellular carcinoma (HCC) with focal nodular hyperplasia (FNH) in the hepatobiliary phase by MRI multimodal parameters. Methods: A retrospective cross-sectional study method was adopted. Clinical data on 15 cases with hyperintense HCC and 15 cases with FNH in the hepatobiliary phase admitted to the First Affiliated Hospital of the Army Medical University from January 2012 to December 2019 were collected. All patients with solitary lesions who underwent Gd-EOB-DTPA-enhanced MRI examinations were included. Surgically resected specimens were verified by pathological and immunohistochemical examination. HCC and FNH imaging features were analyzed by two radiologists. Results: (1) HCC and FNH apparent diffusion coefficient (ADC) values were 1 205.07±239.65×10-3 mm2/s and 1 434.73±217.6×10-3 mm2/s, respectively, and the SIADC difference was statistically significant (P<0.05) between the two groups. (2) In the dynamic contrast-enhanced MRI sequence, 15 cases of HCC were significantly enhanced in the arterial phase, of which 13 cases were characterized by continuous enhancement, and 2 cases were characterized by wash-in and wash-out enhancement. There was no statistically significant difference (P>0.05) between the two groups. SIenhancement rate between HCC and FNH (1.39±0.60 vs. 1.33±0.50, P>0.05) had no significant difference. (3) HCC and FNH morphological features in the hepatobiliary phase included: annular hypointensity: HCC (8 cases) vs. FNH (0 cases); contrast filling defects: HCC (8 cases) vs. FNH (0 cases); linear hyposignal separation: HCC (10 cases) vs. FNH (0 cases); and stellate scars: HCC (0) vs. FNH (5 cases), and there were statistically significant differences (P<0.05) between the two groups . Conclusion: Multimodal MRI have significant value for differentiating hyperintense HCC and FNH in the hepatobiliary phase.

D006528 Carcinoma, Hepatocellular A primary malignant neoplasm of epithelial liver cells. It ranges from a well-differentiated tumor with EPITHELIAL CELLS indistinguishable from normal HEPATOCYTES to a poorly differentiated neoplasm. The cells may be uniform or markedly pleomorphic, or form GIANT CELLS. Several classification schemes have been suggested.

D020518 Focal Nodular Hyperplasia Solitary or multiple benign hepatic vascular tumors, usually occurring in women of 20-50 years of age. The nodule, poorly encapsulated, consists of a central stellate fibrous scar and normal liver elements such as HEPATOCYTES, small BILE DUCTS, and KUPFFER CELLS among the intervening fibrous septa. The pale colored central scar represents large blood vessels with hyperplastic fibromuscular layer and narrowing lumen.
