MSCTA曲面重建技术诊断腹主动脉瘤的应用研究

Value of MSCTA and CPR in the Diagnosis of Abdominal Aortic Aneurysm

目的:分析多层螺旋CT血管成像(MSCTA)曲面重建技术(CPR)在腹主动脉瘤(AAA)诊断中的应用价值。方法:对21例B超提示AAA及5例AAA支架植入术后病例的MSCTA原始数据进行CPR重组,分析CPR图像对AAA的诊断能力。结果:26例AAA MSCTA的CPR图像清晰显示动脉瘤体的形态、与周围结构的关系、血管病的钙化,其中5例腹主动脉支架植入可清晰显示支架部位、范围及通畅程度。结论:CPR图像能准确、直观显示腹主动脉全貌,是轴位图像的重要补充,对AAA的定位及术后随访具有重要的应用价值。

Objective： To explore the applicable value of MSCTA and CPR in diagnosing and treating abdominal aortic aneurysm（AAA）.Methods：21 cases of AAA which were suspected by US and 5cases of abdominal aortic stent implantation were performed MSCTA, the data was analyzed by CPR and generally analyzed with original axial images.Result：All AAA of 21 cases and 5cases of abdominal aortic stent implantation were clearly revealed by CPR, included the shape locality and size of the aneurysm, the relations between the aneurismal bodies and the adjacent main branches of aorta, calcification in the arterial wall or the site range and patency of the stent.Conclusion：CPR has a positive applicable value in diagnosing and treating AAA, axial images served as a basic method, which CPR as important complementary for diagnosing AAA.
