目的
目的：应用CT血管成像技术评价大动脉炎患者的主、肺动脉壁改变。
材料和方法
前瞻性地对12名女性大动脉炎患者和10名健康成人进行了CT血管成像检查。扫描包括三个不同的阶段：平扫(注射造影剂之前)、动脉扫描和延迟扫描。
结果
平扫横断图像显示主动脉壁高密度(10例)和主动脉壁钙化(9例)。动脉期图像显示所有患者周壁增厚1-4 mm，5例活动性疾病患者增强。延迟期CT显示8例患者有环状强化。在动脉期(2例)和延迟期(3例)图像上，也可在主动脉内发现同心的低密度环。2例患者表现为肺动脉壁增厚，并有早期强化和延迟强化。
结论
CT血管造影术可显示大动脉炎患者的血管壁改变。
PURPOSE
To evaluate mural changes in the aorta and pulmonary artery in Takayasu arteritis by using computed tomographic (CT) angiography.
MATERIALS AND METHODS
CT angiography was prospectively performed in 12 women with Takayasu arteritis and in 10 healthy adults. Scanning included three distinct phases: precontrast (before administration of contrast material), arterial, and delayed.
RESULTS
Precontrast transverse images revealed a high-attenuation aortic wall (10 patients) and mural calcifications in the aorta (nine patients). Arterial-phase images revealed circumferential wall thickening of 1-4 mm in all patients and enhancement in five patients with active disease. Delayed-phase CT revealed circumferential enhancement in eight patients. A concentric, low-attenuation ring was also identified inside the aorta on the arterial-phase (two patients) and delayed-phase (three patients) images. In the pulmonary artery, wall thickening was revealed with early and delayed enhancement in two patients.
CONCLUSION
CT angiography may demonstrate changes in the vascular wall in patients with Takayasu arteritis.
