T2-PROPELLER Compared to T2-FRFSE for Image Quality and Lesion Detection at Prostate MRI.
PURPOSE: The primary objective was to compare T2-FRFSE and T2-PROPELLER sequences for image quality. The secondary objective was to compare the ability to detect prostate lesions at MRI in the presence and absence of motion...
