What does this research mean for the field?

Ultrahigh-gradient diffusion-weighted imaging (DWI) at b4500 results in non-diagnostic image quality for prostate MRI, while DWI at b2500 maintains good PI-RADS agreement with DWI at b1500. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

The aim is to assess the impact of ultrahigh b-values on image quality and PI-RADS agreement in prostate MRI.

Acquisition, image quality, and PI-RADS agreement of ultrahigh-gradient DWI in prostate 3-T MRI

Key Points

The aim is to assess the impact of ultrahigh b-values on image quality and PI-RADS agreement in prostate MRI.
Utilized ultrahigh b-values ranging from 2500 to 4500 with gradients of up to 140 T/m.
Evaluated image quality and diagnostic confidence across different b-values for DWI.
Measured PI-RADS agreement between various DWI images.
Overall image quality decreased from good with DWI(b1500) to non-diagnostic with DWI(b4500).
PI-RADS agreement was good between DWI(b1500) and DWI(b2500), but only moderate between DWI(b1500) and DWI(b4500).

Abstract

Acquired ultrahigh b-values (b2500-4500) using ultrahigh gradients of up to 140 T/m were utilized for prostate DWI. Both, overall image quality and diagnostic confidence decreased from good for DWI(b1500) to non-diagnostic for DWI(b4500). PI-RADS agreement between DWI(b1500) and DWI(b2500) was good, while it was only moderate between DWI(b1500) and DWI(b4500).
