title: [Utility of sampling perfection with application optimized contrasts using different flip angle evolutions method in magnetic resonance imaging of carotid artery plaque].
abstract: In the carotid artery plaque diagnosis, it is said that properties evaluation is important. For this inspection, it is general to use electrocardiogram (ECG)-trigger-dark blood (DB)-fat suppression (fs)-turbo spin echo (TSE)-T1 weighted image (T1WI), T2WI, and magnetization prepared rapid gradient echo (MPRAGE) methods though many problems still remain. This time, a comparative study of the carotid artery plaque diagnosis that used the sampling perfection with application optimized contrasts was made. This used different flip angle evolutions method sampling perfection with application optimized contrasts using different flip angle evolutions (SPACE) method that was 3 dimension (3D) imaging procedure that used variable flip angle with the law so far. The subjects were normal volunteers, handmade phantoms changed by T1 and T2 value, and the five patients on five cases who had taken carotid endoarterectomy (CEA) (male, mean 70.6 yr). Findings by the pathologist were obtained for the CEA enforcement patient. There is an excellent result in the contrast ratio by phantom, the signal intensity ratio of a clinical patient, and the comparison with pathological findings. The SPACE method can solve various problems, be evaluated by a properties evaluation of the plaque, a grasp of the range, and an arbitrary section, and be devised as a useful imaging procedure.
