SEMAC and MAVRIC are two recently developed techniques to significantly reduce the geometric distortion caused by metallic implants in MR examinations. However, both two methods are suffering from long scan time due to their intrinsic feature of 3D acquisition. In this abstract, the limitations of these two methods in terms of sampling efficiency are analyzed and an improved implementation MSVAT-SPACE is presented to show the higher imaging speed
