Abstract

To determine the value of contrast-enhanced ultrasound in the diagnosis of benign and malignant hepatic tumors. A total of 83 patients with 123 focal liver lesions (FLLs) underwent contrast enhanced ultrasound (CEUS) examination. The contrast enhanced characterization of FLLs were compared. All the 103 lesions in hepatocallular carcinoma improved quickly in the arterial phase or portal phase. Altogether 98 lesions (95%) washed out during the late phase but the rest 5 lesions (5%) did not. Of the 69 lesions of hepatocellular carcinoma, 53(77%) enhanced global in the arterial phase or portal phase, and the rest 16 (23%) showed inhomogeneous enhancement but no enhancement in the central area during arterial phase or portal phase. A total of 66(96%) presented wash-out during the late phase, and 3(4%) had no wash-out. Of the 34 lesions of metastatic hepatic carcinoma, 24(71%)presented inhomogeneous enhancement in the arterial phase or portal phase, 10(29%) enhanced globally in the arterial phase or portal phase, 32 (94%) presented wash-out during the late phase, and 2(6%) had no wash-out in the late phase. Of the 20 lesions of benign hepatic tumor, 18(90%) presented inhomogeneous enhancement slowly in the arterial phase or portal ph...Continue Reading
