Abstract

The PI-RADS guidelines set out the minimal technical requirements for the acquisition of multiparametric magnetic resonance imaging (mpMRI) of the prostate. However, the rapid diffusion of this technique has inevitably led to variability in scan quality among centres across the UK and the world. Suboptimal image acquisitionreduces the sensitivity and specificity of this technique for the detection of clinically significant prostate cancer and result in clinicians losing confidence in the technique.Two expert panels (one from the UK and one from the ESUR/ESUI) have stressed the importance to establish quality criteria for the acquisition ofmpMRI of the prostate.A first attempt to address this issue has been the publication of the Prostate Imaging Quality (PI-QUAL) score, whichassesses the mpMRI quality against a set of objectivecriteria (PI-RADS version 2.1 guidelines) together with criteria obtained from the image.PI-QUAL represents the first step towards the standardisation of a scoring system toassess the quality of prostate mpMRIprior to reporting and allows clinicians to have more confidence in using the scan to determine patient care. Further refinements after robust consensus among experts at an international level need to be agreed before its widespread adoption in the clinical setting.
