Das kleine hepatozelluläre Karzinom

Abstract

The diagnosis of hepatocellular carcinoma (HCC)-especially the characterization of small lesions <2 cm-continues to be aradiological challenge. In the current S3guideline on diagnosis and therapy of HCC, contrast-enhanced imaging examinations, such as contrast-enhanced ultrasonography (CEUS), computed tomography (CT), and magnetic resonance imaging (MRI), are still the diagnostic standard. HCC in the cirrhotic liver should be diagnosed by its typical contrast-enhanced pattern in the MRI. In addition, the use of quality assurance instruments such as LI-RADS (Liver Imaging Reporting and Data System) contributes to the desired consistency of findings, even with small ambiguous findings. Many studies have shown that the LI-RADS classification reflects the likelihood of HCC and other malignant liver lesions. Guidelines and quality assurance instruments contribute to amore precise diagnosis in patients with suspected HCC. Aguideline-compliant diagnostic algorithm and the LI-RADS should be used across the board for accurate HCC diagnostics.
