Implication

Diagnostic study demonstrates superior tumor detection in patients evaluated for prostate cancer, suggesting added clinical value of diffusion-weighted MRI.

Key Points

To evaluate whether combining diffusion-weighted (DW) imaging with T2-weighted (T2W) magnetic resonance imaging improves prostate cancer detection compared to T2W imaging alone.
Evaluated 60 patients (37 with prostate cancer and 23 without cancer) who underwent T2W and DW imaging with parallel imaging on a 1.5-T superconducting magnet.
Images were reviewed independently by 3 readers to assess cancer detectability.
Diagnostic performance of T2W imaging alone versus combined T2W and DW imaging was analyzed using receiver operating characteristic (ROC) curves.
Mean area under the receiver operating characteristic curve was 0.87 for T2W imaging alone and 0.93 for T2W imaging with DW imaging.
The addition of DW imaging to conventional T2W imaging significantly improved tumor detection compared with T2W imaging alone (P = 0.0468).
