Correlation of proton MR spectroscopic imaging with gleason score based on step-section pathologic analysis after radical prostatectomy
Magnetic Resonance Spectroscopy
MR spectroscopic imaging measurement of prostate tumor (Cho + Cr)/Cit and tumor volume correlate with pathologic Gleason score. There is overlap between MR spectroscopic imaging parameters at various Gleason score levels, which may reflect methodologic and physiologic variations. MR spectroscopic imaging has potential in noninvasive assessment of prostate cancer aggressiveness.
