摘要
目的:探讨多层螺旋CT对肝癌多期扫描的影像特征及其临床应用价值。方法:临床纳入原发性肝癌患者90例,随机分为研究组与对照组,每组45例。研究组采用多层螺旋CT进行动脉期、全肝静脉期、病灶平衡期扫描,对照组采用119〗多层螺旋CT平扫。观察两种扫描方式在病灶显示率及病灶阳性诊断率等方面的差异。结果:研究组CT动脉期、静脉期、平衡期病灶显示率分别为95.56%、91.11%、95.56%,对照组CT平扫显示率为75.56%,研究组各期显示率均要明显高于对照组,差异均有显著性(P<0.05);研究组诊断肝癌42例,诊断阳性率为93.33%,对照组诊断肝癌26例,诊断阳性率为57.78%,差异有显著性(P<0.05);对不同类型肝癌诊断率方面,研究组对巨块型、结节型、弥漫型的诊断准确率分别为100.00%、93.10%、87.50%,对照组对巨块型、结节型、弥漫型的诊断准确率分别为100.00%、50.00%、20.00%,其中结节型、弥漫型诊断准确率两组差异有显著性(P<0.05)。结论:多层螺旋CT对肝癌进行多期扫描,能够为早期临床诊断肝癌提供更多的影像诊断信息,有助提高肝癌的早期诊断率。特别对于结节型、弥漫型等类型的肝癌早期诊断,能够提供更为可靠的诊断依据。
Objective：To analyze the imaging features and clinical application of multi - slice spiral CT scan in the multiple phases of liver cancer. Methods：All 90 patients with primary liver cancer were selected. The subjects were randomly divided into study group and control group,45 cases in each group. The study group adopted the multi - slice spiral CT scan in the arterial phase, hepatic venous phase and equilibrium phase. The control group just adopt- ed the muhi - slice spiral CT scan. The detection rate and positive detection rate were observed. Results： For study group, the detection rate in the arterial phase, hepatic venous phase and equilibrium phase were 95.56%, 91.11% and 95.56%. For control group, the detection rate was 75.56% （ P 〈 0.05 ）. The positive detection rate for study group was 93.33 % （42 cases）. The positive detection rate for control group was 57.78 % （26 cases） （ P 〈 0.05 ）. The detection accuracy on the massive type, nodular type and diffuse type for study group were 100.00% ,93.10% and 87.50%. The detection accuracy for control group were 100.00% ,50.00% and 20.00% （P 〈 0.05 ）. Conclusion： During the muhi - slice spiral CT scan in the multiple phases of hver cancer,it is able to provide more imaging infor- mation on the early diagnosis of liver cancer and improve its early diagnosis rate, especially for nodular type and dif- fuse type.
