OBJECTIVE To assess whether radiologic technologists could be successfully trained to identify abnormalities on mammograms. METHODS Eight radiologic technologists from two different institutions took a pretest, underwent an 8-hour training course followed by a period of preceptorship, and then took a posttest. Seven radiologists also took the pretest and posttest, which consisted of evaluating 1,238 two-view screening examinations, including 318 biopsy-proved cancers. RESULTS Overall, technologists at institution 1 had lower sensitivity (78%) at the pretest, which improved at the posttest (90%). Technologists at institution 2 had lower specificity at the pretest (44%), which improved on the posttest (64%). Hypothetical pairing of radiologists and technologists with use of posttest results revealed an increase in sensitivity (median increase, 12% at institution 1 and 19% at institution 2). CONCLUSIONS Formalized training successfully modified the technologists' skills. Radiologic technologists could be used to increase the number of breast cancers detected at screening mammography.

D012680 Sensitivity and Specificity Binary classification measures to assess test results. Sensitivity or recall rate is the proportion of true positives. Specificity is the probability of correctly determining the absence of a condition. (From Last, Dictionary of Epidemiology, 2d ed) Specificity,Sensitivity,Specificity and Sensitivity
D013679 Technology, Radiologic The application of scientific knowledge or technology to the field of radiology. The applications center mostly around x-ray or radioisotopes for diagnostic and therapeutic purposes but the technological applications of any radiation or radiologic procedure is within the scope of radiologic technology.
