摘要

目的 :比较结节型肝细胞癌（HCC）在螺旋CT增强扫描中

其动脉期、门脉期、延迟期的病灶检出率。方法 :30例结节型Hcc行螺旋CT检查

先平扫

再以 3ml秒团注对比剂 15 0ml

分别作动脉期（注射后 2 5s）和门脉期（注射后 6 0～ 70s）、延迟期扫描（注射后 4～ 6min）。观察病灶的强化方式

统计各期的病灶检出率。结果 :30例中发现肿瘤病灶 5 1个

平扫、动脉期、门静脉期、延迟期扫描的病灶检出率分别是 2 3.5 %、84 .3%、6 6 .7%、72 .5 %。结论 :螺旋CT增强扫描能显示结节型HCC的强化特点

三期结合可明显提高病灶的检出率。

Abstract

Objective:To compare the detected rate of nodular hepatocellular carcinomas (HCC)on spiral CT enhanced scanning of arterial-

portal-

and delay phase. Methods: Spiral CT scanning was performed in 30 cases of nodular HCC. After plain CT examination

arterial phase(25s after injection) and portal venous phase (60～70s after injection)

delay phase (4～6min after injection) were performed with a 150ml bolus injection of contrast material at 3ml/s. The morphology and characteristics on enhanced scans were analyzed and the numbers of the detected lesions were calculated on each phase.Results: 51 nodular HCC of total 30 cases were found.The detected rate on plain scan

arterial phase

portal venous phase and delay phase were 23.5%

84.3%

66.7% and 72.5% respectively.Conclusion: Spiral CT enhanced scanning can fully show the enhanced characteristics of HCC

and combination of three phases could improve the detectrate.
