Quality And Value Of Subspecialty Reinterpretation Of Outside Thoracic Ct Scans Of Patients Referred To A Tertiary Cancer Center

265 Background: At tertiary cancer centers, physicians frequently request reinterpretation of imaging studies performed at outside institutions. The purposes of this study were to determine the quality of outside computed tomography (CT) scans of the chest and compare the accuracy of accompanying radiology reports from outside institutions and our multidisciplinary cancer center. Methods: Two thoracic radiologists graded the quality of 59 outside chest CT scans and generated independent reports for 52 of the scans. A third thoracic radiologist scored the outside reports and reinterpretations for quality. Fisher’s exact tests were used to compare the frequency with which crucial items appeared in outside reports and reinterpretations. Next, two outside thoracic radiologists identified discrepancies between outside reports and reinterpretations (first radiologist) and determined whether the outside report or reinterpretation was more accurate in each case (second radiologist). Finally, the impact of discrep...
