MR-guided prostate biopsy procedures need an improved image SNR. MRS metabolic information could further help deciding from which areas samples need to be taken. As MR data quality crucially depends on local SNR, typically endorectal coils are utilized. In commercial needle holders passive markers fill the available space so that integration of a coil becomes difficult. Inductively coupled coils without direct connection to the MR system have significantly smaller space requirements. Two coil designs were examined for their ability to improve the local SNR at or near the biopsy sample area and for possible integration into commercial biopsy systems.
