The purpose of this study was to prospectively estimate the effectiveness of multi-transmit parallel technique in reduced FOV(Field of View) less than 26 cm. Homogeneity, SNR(signal to noise ratio) and acquisition time were measured and compared by setting FOV less than 26cm on the T1 and T2 weighted images using ACR phantom. The multi-transmit parallel technique resulted in significantly faster image acquisition by 46.8 % in T1 weighted images and 18.9% in T2 weighted images. The homogeneity and SNR values had no significant difference between pre and post application of the multi-transmit parallel technique. In conclusion, this study demonstrates the feasibility of multi-transmit parallel technique in FOV less than 26cm with a rapid acquisition and maintained image quality.
