2024年12月21日 · Hepatocellular carcinoma (HCC), also called hepatoma, is the most common primary malignancy of the liver. It is strongly associated with cirrhosis, from both alcohol and viral etiologies.

2023年10月31日 · Examination of the liver with MRI requires numerous sequences and imaging at multiple times after the administration of contrast. Note: This article is intended to outline some general principles of protocol design.

2025年1月17日 · On post-contrast CT and MRI, regenerative nodules enhance similar to the normal liver parenchyma in both portal venous and hepatocellular/delayed phases, and thus may not be distinguishable in a cirrhotic liver.

2024年3月8日 · The LI-RADS score for a liver lesion is an indication of its relative risk for hepatocellular carcinoma (HCC). The classification system is meant to be used in livers which have risk factors for HCC (e.g. cirrhotic livers).

2024年9月29日 · Fibrolamellar hepatocellular carcinoma is a distinct histological variant of hepatocellular carcinoma characterized on microscopy by laminated fibrous layers between the tumor cells. It is important as it has different demographics and risk factors compared to "standard" hepatocellular carcinomas.

2024年4月27日 · CT/MRI Liver Imaging Reporting and Data System (LI-RADS) is an algorithm for diagnosing and staging hepatocellular carcinoma (HCC) (CT/MRI Diagnostic LI-RADS) or assessing the response of HCC to locoregional treatment (CT/MRI Treatment Response LI-RADS) using CT or MRI with extracellular contrast agents or MRI with hepatobiliary contrast …

2024年5月28日 · Hepatocellular carcinoma surveillance programs have been adopted by some health systems in attempts to effect an early diagnosis of hepatocellular carcinoma in high-risk populations.

2024年12月12日 · Infiltrative hepatocellular carcinoma (HCC), also known as diffuse hepatocellular carcinoma, is an infrequent subtype of HCC, which has particular imaging characteristics. Because of these characteristics, it has been called cirrhotomimetic HCC or cirrhosis-like HCC.

2024年5月15日 · Recommendations for patients with no known risk factors for hepatic malignancy can range from center to center from performing confirmatory examinations (MRI, triphasic CT or scintigraphy) to considering follow-up ultrasound in 6 months to confirm stability, to performing no further imaging evaluation 13.

2024年4月30日 · Dysplastic liver nodules are focal nodular regions (≥1 mm) without definite evidence of malignancy.
