大动脉炎的影像学诊断比较探讨

探讨大动脉炎的多层螺旋CT血管成像表现及其临床应用价值。回顾分析大动脉炎的多层螺旋CT血管成像表现并结合大量文献进行分析讨论。3例大动脉炎患者血管成像表现为动脉管腔狭窄、扩张及管壁增厚。多层螺旋CT血管成像可同时显示大动脉炎的管壁改变和管腔情况，对大动脉炎早期诊断、治疗方法选择有重要意义。

Discussion on the Comparison of Imaging Diagnosis of Takayasu Arteritis

To study multi--slice CT angiography （MSCTA） features of Takayasu arteritis （TA） and to explore the chnical values. The MSCT images of TA were retrospectively analyzed. MSCT examination methods and findings were analyzed and discussed. Multi--slice CT angiography clearly depicted lumenal stenosis and expanding and the wall thickness of the arteries. It is useful for early diagnosis of MSCTA because it allows evaluation of both the wall thickness and the lumenal stenosis, which is especially important for prognosis and the choice of therapy.
