PURPOSE: To determine the diagnostic accuracy of computed tomography (CT) for @entity55 in @entity1 with @entity649 ( @entity649 ). MATERIALS AND METHODS: CT scans were obtained within 1 week of bronchoscopic sampling in 31 @entity1 receiving mechanical ventilation for @entity649 for more than 48 hours. Of 11 @entity1 with @entity55 , five developed symptoms less than 11 days after the onset of @entity649 (early @entity649 ). CT scans were rated for @entity55 independently by four radiologists who were unaware of the clinical diagnosis. Diagnostic accuracy was defined by means of the area under the receiver operating characteristic curve, or A2. RESULTS: Diagnostic accuracy for @entity55 was fair (A2 = 0.69 +/- 0.04 [standard error]) owing to 70% true-negative ratings (vs 59% true-positive ratings). The generalizability coefficient was good (0.79). No single CT finding was significantly different for the presence of @entity55 . Nondependent opacities predominated in 10 (91%) of 11 @entity1 with @entity55 and 12 (60%) of 20 without @entity55 . Nondependent opacities predominated in nine (56%) of 16 @entity1 with early @entity649 and 13 (87%) of 15 with late @entity649 . CONCLUSION: CT has fair diagnostic accuracy for @entity2489 in @entity1 with @entity649 owing primarily to identification of @entity1 without @entity55 . No single CT sign was significantly different for @entity55 , but dependent @entity891 was more common in @entity1 with early @entity649 without @entity55 .
