The purpose of this study was to provide information on the quality of the imagesof the fast 3D TOF MRA by analyzing retrospective the Flow-Related Enhancement MagneticResonance Angiography need to check for Hyper-Acute Stroke according to parameters using the1.5T Standard Reference. The study randomly chose transferred data to PACS (Picture ArchivingCommunication System) targeted 30 patients who perform MRA and Hyper-Acute Stroke MRIexamination at C university hospital from February 2018 to January 2019. For quantitativeevaluation,we measured SNR, CNR to measure average value and standard deviation of signalintensity after setting constant area of interest about cerebral vascular 7 parts according to 3technique (1.5T SRP, 1.5T HAS, 3.0T HAS)protocol. Measurement result is high or in comparison1.5T SRP with 3.0T HAS, it showed 3.0T HAS more higher or same result. Consequently, theanalysis of 7 parts showed that the values of SNR and CNR were 3.0T HAS≥1.5T SRP>1.5THAS. Therefore, the 3.0T fast 3D TOF MRA technique showed significant results in the qualityevaluation of the images.
