WebbMR contouring MRIs were contoured prior to prostate biopsy sessions using the Fusion MR application, Figure 1. DICOM images were uploaded to the system ensuring both T2 and diffusion weighted images (DWI) sequences were available. Other sequences can be uploaded as well. WebbIndeed, we decided to treat the prostate partially, only on the GTV defined by choline-PET/CT or PSMA-PET/CT and MRI, contrary to other authors who chose to retreat the whole prostate [17,19,20,24]. Given that this salvage treatment is not a standard treatment, with possible severe long term toxicities, we chose to only treat the recurrence site, as in …

WebbPurpose: Mistargeting of focal lesions due to inaccurate segmentations can lead to false-negative findings on MRI-guided targeted biopsies. The purpose of this retrospective study was to examine inter-reader agreement of prostate index lesion segmentations from actual biopsy data between urologists and radiologists.
