Axial T2w imaging (a), DWI with a b value of 150 s/mm2 (b), ADC map (c) and DCE acquisition (d) of a study that was given a PI-QUAL score of 1. All MR sequences are below the minimum standard of diagnostic quality as per PI-RADS v.2.1 technical recommendations. In particular, T2w imaging and DWI (ac) show motion artefacts, no high b value has been acquired (b), the field of view is too large on DWI (21 × 35 cm, in b, c) and on DCE sequences (21 × 33 cm in d), and there is no fat suppression of DCE sequences (d)
