Abstract
To the best of our knowledge, studies comparing PROPELLER and the conventional Cartesian MRI have
mostly been reported on motion sensitivity, and there has been no focused study on the standard phantom
imaging to compare them. The purpose of this study was to investigate the effect of PROPELLER method on
ACR guideline QA protocol compared to Cartesian method. In this study, we compared the ACR phantom
image quality of T2WI acquired on PROPELLER and conventional Cartesian method. In addition, we performed
comparisons using different AFs (acceleration factors). For quantitative analysis SNR, geometric accuracy,
high-contrast spatial resolution, slice thickness accuracy, slice position accuracy and low-contrast object
detectability were measured on the acquired images. There were no statistically significant differences in the 6
quantification values for both methods (p > 0.05). In conclusion, we found that PROPELLER method provided
a comparable SNR to Cartesian method, regardless of the various Afs
