Diffusion-weighted MRI (DW-MRI) highly accurate in detecting prostate tumours. In a Renal&Urology News article dated 14 August 2014, Jody Charnow reports the results of a small- scale study undertaken by Lauren J Bains MD et al at the University of Bern in Switzerland. Charnow summarises the study and its finding in these terms: “Diffusion-weighted magnetic resonance imaging (DW- MRI) noninvasively detects significant prostate tumors with a high probability and without contrast medium or an endorectal coil...The researchers prospectively studied 111 men with prostate and/or bladder cancer who underwent DW-MRI of the pelvis without an endorectal coil prior to radical prostatectomy (78 patients) or cystoprostatectomy (33 patients). Based on qualitative imaging analysis, 3 independent readers blinded to clinical and pathologic data assigned a prostate cancer (PCa) suspicion grade...The sensitivity and specificity of DW-MRI for detecting significant PCa was 89%–91% and 77%–81%, respectively, for the 3 readers. The median reading time was 13–18 minutes, with good inter-reader agreement.” The Charnow article can be read here or here: http://tinyurl.com/n9ywdws
