The role of computed tomography in assessing XXXX prior to thoracoscopy.

@entity1 @entity1143 @entity5 @entity1151 @entity456
PURPOSE OF REVIEW: Computed tomography (CT) scanning is part of the routine diagnostic work up of @entity1 with suspected @entity5 but has a wide variation in the reported sensitivity and specificity. This review was to appraise the recent literature on the utility of CT scanning. RECENT FINDINGS: When investigating @entity1 for suspected @entity5 , the sensitivity of a malignant CT report may be higher than previously reported (68%), but the specificity seems significantly lower (78%). The predictive value of CT scanning (on all @entity1 with @entity1143 ) may be increased using a CT scoring system. Recent meta-analyses of the utility of PET give differing opinions on the value of this imaging modality. Further work needs to be done to define its place in the diagnostic pathway. SUMMARY: CT scoring systems may allow further risk stratification. However, a low negative predictive value of a 'negative' CT scan could lead to false reassurance and missed @entity5 . PET/CT does not currently appear to add additional diagnostic value. @entity1151 should be considered in all @entity1 being investigated for clinically suspected malignant @entity456 . Respiratory physicians should be mindful of rare or unusual presentations.
