摘要
目的探讨利用16排螺旋CT血管成像技术对膈下动脉的显示,评价其在显示膈下动脉特别是作为原发性肝细胞癌的肝外营养血管时的临床应用价值。方法收集47例未经治疗的原发性巨块型肝细胞癌(肝细胞癌组)和78例腹部无明显器质性病变(对照组)患者的腹部CTA资料,对所有图像分别采用MIP、CPR和VR三种重建技术观察其显示双侧膈下动脉的能力,并测量其右侧膈下动脉的直径。结果三种重建方法显示膈下动脉的能力有显著性差异,MIP明显优于CPR及VR,CPR又优于VR。肝细胞癌组右侧膈下动脉的平均直径为2.3±0.3 mm(1.6～2.8 mm),对照组右膈下动脉的平均直径为2.1±0.3 mm(1.2～2.8 mm)。肝细胞癌组右膈下动脉的直径大于对照组,差异具有统计学意义。结论 16排螺旋CT血管成像技术可快速、精确、非损伤性的显示双侧膈下动脉,能显示膈下动脉参与供血的直接征象(有分支进入瘤内)和间接征象(膈下动脉增粗),在肝细胞癌病人TACE术前方案的制订和手术方式的选择具有重要的临床意义。
Objective To determine the efficacy of 16-slice spiral CT angiography for delineating the inferior phrenic arterial supply of hepatocellular carcinoma （HCC）. Methods Abdominal CT angiography of 47 patients with primary massive hepatocellular carcinoma （HCC group） and 78 patients without abdominal disease （control group） was retrospectively analyzed. The appearance and diameters of the inferior phrenic arteries using maximum intensity projection （MIP）, curved planar reformation （CPR） and volume rendering （VR） reconstruction techniques were compared. Results MIP was significantly better than CPR and VR; CPR was significantly better than VR for depicting the inferior phrenic artery . The mean diameter of the right inferior phrenic artery was significantly larger in the HCC group （2.3s- 0.3 mm, range 1.6-2.8 mm） than that in the control group （2.1±0.3 mm, range 1.2-2.8 mm）. Conclusion 16-slice spiral CT angiography can display the inferior phrenic arterial supply of HCC in a fast, accurate and non-traumatic manner. It is useful for guiding TACE treatment in HCC.
