Abstract:
Objective To assess the prediction value of nonbronchial systemic arterial supply in hemoptysis patients with non-enhanced CT. Methods Fifty-six consecutive patients with hemoptysis underwent non-enhanced CT. Thickness of pleural adjacent to parenchymal lesion larger than 3 mm was regarded as index of nonbronchial systemic arterial supply. Conventional angiography was used as the standard of reference. CT findings were compared with those of conventional angiography. The sensitivity, specificity, and accuracy of CT for predicting nonbronchial systemic arterial supply were assessed. Results The sensitivity, specificity and accuracy of CT for predicting nonbronchial systemic arterial supply were 72.73%, 95.00% and 91.11%, respectively. Sensitivity was higher when nonbronchial systemic arterial supply located in superolateral and posterolateral lung, and lower in anteromedial and inferior lung. Specificity and accuracy were high for predicting nonbronchial systemic arterial supply in every locations. Conclusion Non-enhanced CT can predict nonbronchial systemic arterial supply in patients with hemoptysis, which is helpful for selecting angiography and embolization.
