Standardisation of prostate multiparametric MRI across a hospital network: a London experience.

摘要: National guidelines recommend prostate multiparametric (mp) MRI in men with suspected cancer before biopsy. In this study, we explore mpMRI protocols across 14 London hospitals and determine whether standardisation improves diagnostic quality. An physicist facilitated set-up several regional hospitals, working together experienced uroradiologists who judged Radiologists from the participated assessment optimisation of image quality, assessed according to both PiRADSv2 recommendations on ability “rule in” and/or out” cancer. Image quality sequence parameters representative scans were evaluated 23 MR scanners. Optimisation visits performed improve 2 radiologists scored pre- post-optimisation. 20/23 protocols, consisting 111 sequences, optimised by modifying their parameters. Pre-optimisation, only 15% T2W images non-diagnostic, whereas 40% ADC maps, 50% high b-value DWI 41% DCE-MRI considered non-diagnostic. Post-optimisation, scores increased 80% 74% 88% be partially or fully diagnostic. sequences not optimised, due higher baseline scores. Targeted intervention at a level can implications for improving detection rates targeted biopsies.
