作者评价磁共振（MR）成像在高须动脉炎（TA）诊断中的应用价值。使用1.5 t系统获得77例TA患者（74例女性，3例男性）的MR图像，并将结果图像与常规血管造影所得图像进行比较。主动脉病变，包括狭窄、扩张、动脉瘤、壁增厚和附壁血栓，在MR成像上清晰可见，特别是在主动脉长轴图像上。此外，在电影磁共振图像中可以清楚地看到主动脉瓣反流，这在TA患者中经常发生。此外，主动脉弓附近的主动脉分支血管病变可见，尽管远端病变通常不太清楚。肺动脉病变，包括闭塞和扩张，也被看到。作者得出结论，MR成像可以清楚地描绘TA患者全身和肺动脉的各种血管病变，从而能够明确诊断该疾病。
The authors evaluate the usefulness of magnetic resonance (MR) imaging in the diagnosis of Takayasu arteritis (TA). MR images of 77 patients with TA (74 women, three men) were obtained with a 1.5-T system, and the resulting images were compared with those obtained at conventional angiography. Aortic lesions--including stenosis, dilatation, aneurysms, wall thickening, and mural thrombi--were clearly visualized at MR imaging, particularly in aortic long-axis images. Further, aortic regurgitation, which occurs frequently in patients with TA, was clearly seen in cine MR images. Also, aortic branch vessel lesions adjacent to the aortic arch were well visualized, although distal lesions were often not as clear. Pulmonary arterial lesions, including occlusion and dilatation, were seen as well. The authors conclude that MR imaging can clearly depict various vascular lesions in both the systemic and pulmonary arteries of patients with TA, thus enabling a definitive diagnosis of the disease.
