Ultra high spectral and spatial resolution of proton MR spectroscopic imaging of the prostate at 7T

Purpose: Proton MR spectroscopic imaging (MRSI) of the prostate has been proven to help in the detection of prostate cancer. At 1.5T however, the sensitivity of this method is often insufficient to detect small cancer foci, and moreover, the low spectral resolution causes overlap of signals from choline, creatine and polyamines, hampering accurate assessments. By moving to 7T with its potentially increased spectral and spatial resolution, MRSI of the prostate is expected to improve the sensitivity in tumour detection and localization. Materials and methods: To work around some of the challenges of MRSI of the pr…
