Problem Undersampling of prostate cancer can lead to incorrect surveillance (AS) patient selection. Aim: to determine if T2-weighted (T2w) MRI and diffusion weighted MRI (DWI) could contribute in AS patient selection by comparing radiologist reading of stage and Gleason score(GS) to prostatectomy. Methods Twelve prostatectomy patients were retrospectively selected by biopsy criteria and a performed 3T MRI preprostatectomy. Four radiologists scored T2w-MRI and T2w-MRI in combination with DWI. Results AUC values for T2w-MRI prediction of AS patients varied from 0,812 for inexperienced reader to 0,812-1,0 for experienced readers. Conclusion T2w-MRI could be of additional value in AS patient selection.
