Clinically acceptable scan time is very important in DTI which is essential for neurologic imaging and there have been ongoing efforts to make the scan time faster. Multi-Band SENSE simultaneous multi slice, also called multiband, is a better solution to reduce scan time. In order to compare the performance of SENSE and MBSENSE on DTI acquisitions images were acquired using ACR phantom with factor 2 on both groups. The MBSENSE group showed lower SNR values of center and peripheries than the SENSE in slice 7 (8.78 % and 8.99 % respectively). However, SNR loss is minimal. The SNR values profiles showed a equality from the center to peripheries of the image slice at both MB-SENSE and SENSE. The difference of SNR profiles was approximately 3 % at the center and 9 %-15 % at peripheries at SENSE. This became 3 % at the center and 10 %15 % at peripheries at MB-SENSE. Therefore, this study has studied and verified the effect of MB-SENSE in temporal resolution over SENSE which are applied on DTI technique using ACR QA program.
