Abstract
OBJECTIVES: To compare the spectral quality of prostate magnetic resonance spectroscopic imaging (MRSI) at 1.5Tesla with endorectal coil (ER-1.5T) to MRSI at 3.0Tesla without coil (3.0T). METHODS: In 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. RESULTS: There 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). CONCLUSION: There 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.
