{"entity":{"id":"pi-qual","kind":"term","name":"PI-QUAL (prostate MRI image quality score)","aka":["PI-QUAL","Prostate Imaging Quality"],"tldr":"PI-QUAL is a 1 to 5 score for how good the pictures in a prostate MRI are, because a poor-quality scan can miss cancer whatever PI-RADS score it is given.","summary":"The PRECISION trial showed MRI-targeted biopsy finds more prostate cancer than standard biopsy, but that depends on scan quality. Giganti and colleagues (European Urology Oncology 2020) introduced the Prostate Imaging Quality score: 1 means no sequence is of diagnostic quality and 5 that every sequence is independently of optimal quality. In 58 PRECISION scans read by two radiologists, 95% were of sufficient diagnostic quality (PI-QUAL 3 or more) and 60% of good or optimal quality (4 or more); the contrast-enhanced sequence was the weakest. The authors called for further validation.","asOf":"2026-11-04","links":[{"label":"Giganti et al., Prostate Imaging Quality (PI-QUAL): a new quality control scoring system for multiparametric MRI of the prostate from the PRECISION trial (Eur Urol Oncol 2020)","url":"https://doi.org/10.1016/j.euo.2020.06.007"}],"tags":[],"related":["pi-rads","precise-recommendations"],"cancers":["prostate"],"sections":[],"technologies":["mp-mri"],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"category":"Diagnostics & imaging"},"route":"/terms/pi-qual/","neighbours":{"term":[{"id":"pi-rads","kind":"term","name":"PI-RADS (Prostate Imaging Reporting and Data System)","route":"/terms/pi-rads/"},{"id":"precise-recommendations","kind":"term","name":"PRECISE score (prostate MRI on active surveillance)","route":"/terms/precise-recommendations/"}],"cancer":[{"id":"prostate","kind":"cancer","name":"Prostate cancer","route":"/cancers/prostate/"}],"technology":[{"id":"mp-mri","kind":"technology","name":"Multiparametric prostate MRI (PI-RADS)","route":"/technologies/mp-mri/"}]}}
