Standard magnetic resonance imaging of the prostate lacks sensitivity in the diagnosis and staging of prostate cancer.
Standard magnetic resonance imaging (MRI) of the prostate lacks sensitivity in the diagnosis and staging of prostate cancer (PCa). A novel, enhanced MRI diffusion technique using restriction spectrum imaging (RSI-MRI) was developed to improve the operating characteristics of prostate MRI in the detection and characterization of Pca.
The efficacy of RSI-MRI technique was compared with standard MRI for detecting extraprostatic extension (EPE).
28 PCa patients underwent MRI and RSI-MRI prior to radical prostatectomy and 10 patients had pT3 (prostate cancer, stage 3) disease.
Of the 27 patients who were evaluated, preoperative standard MRI identified two of the nine-pT3 extraprostatic extension.
RSI-MRI identified EPE in eight of nine (89%) patients. RSI-MRI correctly identified pT2 disease in the remaining 18 patients.
RSI-MRI technology is feasible and shows promise for substantially improving PCa imaging.
