[Abstract] Objective To explore the value of self-developed 16-channel high-resolution pelvic-specific coil (16C) in pelvic 3.0 T MRI.Methods and Materials Thirty-five patients underwent routine pelvic MRI were prospectively included, and the same axial and sagittal T2WI sequences were acquired with a 16C coil and a 32-channel body coil (32C), respectively. Signal to noise ratio (SNR) and contrast to noise ratio (CNR) of the third sacral vertebrae, myometrium, peripheral band of prostate, rectal wall, and internal obturator muscle were compared between images of the same sequences acquired with the two coils. Qualitative image quality and rectal wall depiction were evaluated by two radiologists for both groups.Results Compared with 32C, SNR of third sacral vertebrae, myometrium, peripheral band of the prostate on T2WI sagittal images, SNR of intraocclusal muscle on T2WI axial images, CNR of third sacral vertebrae, myometrium on T2WI sagittal images and CNR of rectal wall on T2WI axial images were all higher, and all difference were statistically significant (P<0.05). Rectal wall depiction on T2WI axial images and all qualitative image quality were better in 16C group than that of 32C group (P<0.05).Conclusions Compared with conventional 32C coils, images acquired with 16C coils have better imaging quality and diagnostic confidence.
