The already low coupling between an external coil array and an endorectal coil, makes it possible to obtain uniform MRI of the human prostate when transmitting only with the external array and receiving with all elements, while for prostate MR spectroscopy, all coil elements can be used as transceivers using active decoupling. Therefore, uniform extended field of view MRI and high B1, low TE MRSI can be acquired from the prostate location at 7T.
