From: Role of diffusion-weighted MRI in diagnosis and post therapeutic follow-up of colorectal cancer

  Sensitivity Specificity PPV NPV Accuracy
Conventional 8/10 (80%) 6/10 (60%) 8/12 (66.7%) 6/8 (75%) 14/20 (70%)
DWI 9/10 (90%) 8/10 (80%) 9/11 (81.8%) 8/9 (88.9%) 17/20 (85%)
ADC 10/10 (100%) 8/10 (80%) 10/12 (83.3%) 8/8 (100%) 18/20 (90%)
  1. PPV positive predictive value, NPV negative predictive value
