We found substantial agreement (κ = 0.77; percent agreement = 80%) between two expert radiologists when assessing prostate MRI quality for each single PI-QUAL score (1 to 5). The composition of the PI-QUAL will need to undergo further refinements.
Fig. 1: Three cases of PI-QUAL score.
From left to right for each row: axial T2-weighted, diffusion (b-values and ADC map) and dynamic-contrast enhanced imaging.
PI-QUAL 2: only one sequence is of acceptable diagnostic quality (T2-WI). It is not possible to rule in and to rule out all significant lesions.
PI-QUAL 3: two sequences taken together are of acceptable diagnostic quality. It is possible to rule in but not to rule out all significant lesions.
PI-QUAL 4: at least two sequences are independently of diagnostic quality, and it is possible to rule in and rule out all significant lesions.
