The diagnostic accuracy of three-dimensional constructive interference in steady state (CISS) magnetic resonance (MR) imaging was evaluated for the assessment of idiopathic moyamoya disease. Six consecutive patients underwent MR angiography, CISS imaging, and digital subtraction angiography. MR angiography and CISS imaging visualization of the steno-occlusive changes in the distal internal carotid arteries and the development of moyamoya vessels in the basal cistern were compared to the results obtained by digital subtraction angiography. MR angiography revealed the steno-occlusive changes correctly in nine and overestimated the changes in three of 12 hemispheres examined. CISS imaging showed the steno-occlusive changes defined as decreased caliber of the internal carotid artery correctly in two, underestimated the changes in nine, and overestimated the changes in one of the 12 hemispheres. MR angiography detected moyamoya vessels correctly in five and underestimated the vessels in seven of the 12 hemispheres. CISS imaging revealed the moyamoya vessels correctly in 10, underestimated the vessels in one, and overestimated the vessels in one of the 12 hemispheres. CISS imaging can supplement MR angiography in the non-invasive diagnosis of moyamoya disease, especially for the evaluation of moyamoya vessels.
评估三维稳态构成干扰（CISS）磁共振（MR）成像对特发性烟雾病的诊断准确性。连续6例患者接受了MR血管造影、CISS成像和数字减影血管造影。将MR血管造影和CISS成像显示的颈内动脉远端狭窄闭塞性改变及基底池烟雾状血管的情况与数字减影血管造影的结果进行比较。MR血管造影在12个半球中的9个正确显示了狭窄闭塞性改变，在3个中高估了改变。CISS成像在12个半球中的2个正确显示了定义为颈内动脉管径减小的狭窄闭塞性改变，在9个中低估了改变，在1个中高估了改变。MR血管造影在12个半球中的5个正确检测到烟雾状血管，在7个中低估了血管。CISS成像在12个半球中的10个正确显示了烟雾状血管，在1个中低估了血管，在1个中高估了血管。CISS成像可在烟雾病的无创诊断中补充MR血管造影，尤其是对烟雾状血管的评估。
