摘要
目的评估肝细胞癌多层螺旋CT血管成像(MSCTA)方法的临床应用价值。方法对44例肝细胞癌和30例正常肝脏行MSCT腹部血管成像,采用最大密度投影(MIP)和容积再现(VR)对图像进行分析。结果两组的腹腔血管显示率有显著性差异,肝细胞癌组轴位、MIP、VR对各级血管受侵例数比较有显著性差异。结论MSCT血管成像结合MIP、VR,在肝细胞癌诊断中直观显示腹腔血管的形态,多角度观察肿瘤与血管的关系,有望成为肝细胞癌治疗方案选择的常规检查方法。
Objective To evaluate the clinical value of multislice spiral CT angiography （MSCTA） on hepatocellular carcinoma （HCC）. Methods 44 patients with hepatocellular carcinoma and 30 cases of normal patients were processed with MSCTA on abdomen, to analyze the images by maximum intensity projection （MIP） and volume rendering （VR）. Results Displaying rate of abdomen blood vessels existed significant difference between two groups, it had significant difference of involved blood vessels between axis, MIP and VR in the HCC group. Conclusion MSCTA combining with MIP and VR reconstruction can directly show appearance of abdomen blood vessels, and view the relationship of tumors and vessels in different directions. It would become routine examination of treatment plan choice on HCC.
