Reader Study 👩‍⚕️👨‍⚕️¶

The PI-CAI: Reader Study is introduced to estimate the performance of radiologists at csPCa detection and diagnosis in MRI. It is facilitated by the assessments of 50+ international prostate radiologists using a subset of 400 cases from the hidden testing cohort. For each case, radiologists complete their assessments in two rounds. At first, using bpMRI sequences only, enabling head-to-head comparisons against AI trained on bpMRI. And then, using full mpMRI sequences, enabling comparisons between AI and current clinical practice (PI-RADS v2.1).¶

Figure. Distribution of radiologists who completed the PI-CAI: Reader Study, representing 62 radiologists (45 centers, 20 countries) as of 29 May, 2023. Reader experience varies between 1 and 23 years (median 7 years), where 74% (46) of readers can be categorized as “expert” based on 2020 ESUR/ESUI consensus statements (de Rooij et al., 2020).
