Summary
Brief summary (as posted)
Recent developments in MRI techniques allow ultra-high gradient strength diffusion imaging and deep learning (DL) reconstruction in clinical routine. However, its usability in biparametric MRI (bpMRI) of the prostate has not been well studied. The aim is to establish a super-fast 3-minutes bpMRI protocol at 3 Tesla using high gradient strength and DL reconstruction and compare it against a full, multiparametric MRI (mpMRI) protocol.

- description
- Three radiologists with 3, 11 and 12 years of experience in prostate MRI read separately and blinded to personal and clinical parameters (name, age, patient history, value of the prostate specific antigen, clinical examination and transrectal ultrasound) the full bpMRI protocol and graded the lesions according to the PI-RADS classification. Per patient, only the highest graded lesion and its respective prostate zone was noted. If there were two distinct lesions with the highest PI-RADS score in both the peripheral and transitional zone, both were noted. After a washout period of one month all readers did the same for the mpMRI protocol. Both the agreement of biparametric and multiparametric MRI PI-RADS scores for the whole prostate, and for the specific zonal distribution (peripheral and transitional zone) were assessed by calculation of Cohens's κ, interpreted as follows: \<0.5 = poor; 0.5-0.75 = moderate; 0.75-0.9 = good; \>0.9 = excellent.
