B shows the respective segmentation in the CT scan (segmentation in green). Mean intensity of the segmentation was 15.8 and radiomic majority vote was high risk. C shows an axial slide of the radiotherapy plan in colorwash with dose escalation in the area of the local recurrence. D shows the prostate-specific antigen (PSA) values of time. Time point of radical prostatectomy (RPE), biochemical recurrence BCR), and salvage radiotherapy (sRT) are highlighted
