We hypothesize that the newly developed wheel encoding order (Fast 3D wheel: i.e. Fast 3Dw) method can reduce examination time as well as compressed sensing (CS) with parallel imaging (PI) technique (Compressed SPEEDER) and obtain contrast-enhanced MR examination without any degradation of image quality as compared with conventional PI technique in suspected brain metastases patients. The purpose of this study was to compare the capability for examination time reduction and image quality and diagnostic performance improvements among conventional PI, CS and Fast 3Dw methods on contrast-enhanced MR examination for brain metastases screening.
