The sensitivity, specificity, positive predictive and negative predictive values of radiologist and the trainee radiologist were calculated.

The sensitivity, specificity and accuracy of trainee radiologist for intetpretation of mammogram with the aid of Med Expert were 800/o, 96% and 90% respectively. For ultrasowd it was 900/o, 83% and 85.90At respectively There was lower sensitivity but higher specificity obtained by the trainee radiologist using Med Expert compared to the radiologist interpretation However, the overall accuracy of trainee radiologist using Med Expert was higher compared to radiologist The kappa agreement between the radiologist and trainee radiologist for mammogmm was 0.6 and that for the ultrasound was 0.8.
