This study examined the effectiveness of the multitransmit parallel technique on the MRI scan time reduction by removing the dielectric effect. The T1 and T2 weighted images of the patients' hip joint were acquired with and without a multitransmit technique. The ROIs were located in the head of femur and iliopsoas muscle. The SNR, CNR and scan time were measured and compared. There was no difference in the images with and without multitransmit. In contrast, the acquisition time was decreased by 42.8% in T1WI and 49.7% in T2WI. In conclusion, this study demonstrated that significant scan time reductions can be accomplished without any differences in the image quality in hip joint MRI by applying the multitransmit parallel technique. Furthermore, the multitranstmit technique is useful in other body parts to resolve the long scan time of an MRI examination.
