| description | •Computed DWI is a post-processing technique without additional acquisition time.•Computed DWI can be implemented in whole-body MRI protocols for prostate cancer.•Computed WB-DWI has good diagnostic performance for primary prostate cancer.
To investigate the utility of post-acquisition computed diffusion-weighted imaging (cDWI) for primary prostate cancer (PCa) evaluation in biparametric whole‐body MRI (bpWB-MRI).
Patients who underwent pelvic MRI for PCa screening and subsequent bpWB-MRI for staging were included.
Two radiologists assessed the diagnostic performance of the following datasets for clinically significant PCa diagnosis (grade group ≥2 according to the Prostate Imaging-Reporting and Data System, version 2.1): bpMRI2000 (axial DWI scans with a b-value of 2,000 s/mm2 + axial T2WI scans from pre-biopsy pelvic MRI), computed bpWB-MRI2000 (computed WB-DWI scans with a b-value of 2,000 s/mm2 + axial WB-T2WI scans), and native bpWB-MRI1000 (native axial WB-DWI scans with a b-value of 1,000 s/mm2 + axial WB-T2WI scans). Systemic biopsy was used as reference standard.
Fifty-one patients with PCa were included. The areas under the curve (AUCs) of bpMRI2000 (0.89 for reader 1 and 0.86 for reader 2) and computed bpWB-MRI2000 (0.86 for reader 1 and 0.83 for reader 2) were significantly higher (p |
