The diagnosis of small hepatocellular carcinomas: efficacy of various imaging procedures in 100 patients.

Portal-phase contrast-enhanced helical CT for the detection of malignant hepatic tumors: sensitivity based on comparison with intraoperative and pathologic findings.

“…The mean maximum diameter of the missed lesions was 9 mm (range, 4-20 mm). The subsegmental location of the missed nodules was as follows: n = 1 in segment 2, n = 2 in segment 4, cm or less, ranging from 0% to 47% [1][2][3][4]. In this study, the sensitivity for nodules 1 cm on less was 56%, which is manginally better than the results reported for incremental CT, but which is still quite low.…”

Screening for hepatocellular carcinoma

“…52 Sensitivity can be improved still further by using techniques such as lipiodol-CT scanning. Sensitivities of 93% to 97% have been reported, 53,54 although the level falls to 86% for tumors less than 1 cm. All of these radiological techniques are also subject to unquantified false-positive rates.…”

Hepatocellular carcinoma screening in patients waiting for liver transplantation: A decision analytic model

“…[34][35][36]38,44 The sensitivity of U/S in detecting HCC ranges from 55% to 85%. 34,[45][46][47][48][49]50 U/S has specificity between 90% and 94% in detecting HCC. 34,[45][46][47][48][49] The sensitivity of CT in detecting HCC varies with the size of the tumor.…”
