Abstract

PURPOSE

To use computed tomography (CT) during arterial portography (CTAP) and CT arteriography to compare the hemodynamic properties of early hepatocellular carcinoma (HCC) with those of small HCC.

MATERIALS AND METHODS

Forty-four early HCCs (mean diameter, 1.5 cm) in 37 patients (26 men and 11 women aged 52-74 years; mean age, 59.2 years) were studied. CTAP was performed on 35 early HCCs, CT arteriography on 20, and both studies on 11. CTAP, CT arteriography, or both were performed on 90 small HCCs (mean diameter, 2.0 cm) in 57 patients (44 men and 13 women aged 48-71 years; mean age, 61 years). The findings for small HCC were compared with those for early HCC.

RESULTS

CTAP depicted 23 early HCCs as hypoattenuating masses and 12 as isoattenuating. CT arteriography depicted 11 early HCCs as hypoattenuating masses, six as isoattenuating, and three as hyperattenuating. CTAP depicted 85 of 88 small HCCs as hypoattenuating masses and three as isoattenuating. CT arteriography depicted 13 of 14 small HCCs as hyperattenuating masses.

CONCLUSION

CTAP, the standard of reference for the detection of small HCC, is not sensitive enough for the detection of early HCC.

摘要

目的

在动脉性门静脉造影（CTAP）和CT血管造影过程中使用计算机断层扫描（CT），比较早期肝细胞癌（HCC）与小肝癌的血流动力学特性。

材料与方法

研究了37例患者（26例男性和11例女性，年龄52 - 74岁；平均年龄59.2岁）中的44个早期HCC（平均直径1.5 cm）。对35个早期HCC进行了CTAP检查，20个进行了CT血管造影检查，11个同时进行了这两项检查。对57例患者（44例男性和13例女性，年龄48 - 71岁；平均年龄61岁）中的90个小肝癌（平均直径2.0 cm）进行了CTAP、CT血管造影或两项检查。将小肝癌的检查结果与早期HCC的结果进行比较。
