Comparative study of diagnostic value between IVIM and DWI for prostate cancer at 3.0 T magnetic resonance

Abstract Objective To quantitatively compare the diagnostic and differential value of intra-voxel incoherent motion imaging (IVIM) diffusion weighted (DWI) for prostate cancer (PCa) benign prostatic hyperplasia (BPH). Methods 68 cases confirmed by pathology, including 33 PCa 35 BPH were analyzed retrospectively. All patients underwent T1WI, T2WI, DWI IVIM sequences to obtain apparent coefficient (ADC), pure (Pure-ADC/D), standard (standard-ADC/Ds), fast (fast-ADC/ D *), fraction ( f ) values. multiple parameters statistically diagnosis PCa. P < 0.05 was considered as significant. Results The differences in , Ds, ADC values between groups significant (all 0.001), respectively. Among them, model had highest efficiency PCa, area under curve (AUC) 0.967, AUC combined with reaches 0.973. Conclusion efficacy higher than quantitative parameter DWI. efficiency. more effective, advantageous
