PURPOSE
To evaluate magnetic resonance (MR) angiography and MR imaging in assessment of moyamoya disease.
MATERIALS AND METHODS
The cases of 26 patients with moyamoya disease were evaluated prospectively. After three-dimensional time-of-flight 1.5-T MR angiography and MR imaging, images were evaluated in blinded separate interpretation.
RESULTS
MR angiography and MR imaging accurately depicted 217 (82%) and 184 (70%) of 264 arteries, respectively, but the degree of stenosis was overestimated in the other arteries. Basal cerebral moyamoya vessels were depicted in all 52 hemispheres with conventional angiography and in 42 (81%) and 48 (92%) hemispheres with MR angiography and MR imaging, respectively. The respective sensitivity and specificity for diagnosis of moyamoya disease were 73% and 100% for MR angiography, 92% and 100% for MR imaging, and 92% and 100% for MR angiography plus MR imaging.
CONCLUSION
Assessment of moyamoya disease is most thorough with MR angiography and MR imaging.
目的
评估磁共振（MR）血管造影和MR成像在烟雾病评估中的作用。
材料与方法
对26例烟雾病患者进行前瞻性评估。在进行三维时间飞跃法1.5-T MR血管造影和MR成像后，由不同人员在不知情的情况下分别对图像进行评估。
结果
MR血管造影和MR成像分别准确显示了264条动脉中的217条（82%）和184条（70%），但其他动脉的狭窄程度被高估。在所有52个半球中，传统血管造影均显示了基底节区烟雾病血管，MR血管造影和MR成像分别在42个（81%）和48个（92%）半球中显示了该血管。MR血管造影诊断烟雾病的敏感性和特异性分别为73%和100%，MR成像分别为92%和100%，MR血管造影联合MR成像分别为92%和100%。
结论
MR血管造影和MR成像对烟雾病的评估最为全面。
