Abstract
ObjectivesTo compare the spectral quality of prostate magnetic resonance spectroscopic imaging (MRSI) at 1.5 Tesla with endorectal coil (ER-1.5T) to MRSI at 3.0 Tesla without coil (3.0T).MethodsIn 30 patients, the spectral quality of 6107 voxels at ER-1.5T and that of 5667 at 3.0T were visually evaluated by three radiologists.ResultsThere were 57.6% good quality voxels at ER-1.5T versus 64.3% at 3.0T (P= .121). The posterior two rows showed better quality at ER-1.5T (P= .047).ConclusionThere is no significant difference in overall spectral quality between ER-1.5T and 3.0T, although ER-1.5T shows better quality close to the endorectal coil.
