Abstract

Provided are systems and methods for obtaining MRI image data having high SNR. According to some embodiments, the systems and method provide for front to back positioning of pelvic coil assemblies. According to one embodiment, the pelvic coil assemblies are configured to accommodate the male anatomy of the patient being imaged. By accommodating the male anatomy, the pelvic coil assemblies are configured for optimal placement proximate to the patient's prostate. Further, closer positioning enables imaging of a smaller volume of the patient's tissue. Proximity and limitation in volume provide for significant improvement in SNR. The improved SNR can be leverage according to various embodiments of the systems and method into shorter scan times and/or more detailed imaging of a region of interest. Additional embodiments provide adjustable pelvic coil assembly facilitating their use across varying patient populations.
