Objective  To compare the bronchial arteriography through multidetector-row CT (MDCT) with the digital subtraction angiography (DSA) via femoral artery, and evaluate the application value of bronchial arteriography through MDCT in the diagnosis and treatment of hemoptysis.
Methods  133 cases complained of hemoptysis were examined by MDCT and DSA via femoral artery respectively to perform bronchial arteriography, and the differences of image results by two methods were compared.
Results  129 cases with abnormal bronchial arteries were confirmed by DSA via femoral artery, 117 cases were checked by MDCT [ the positive rate was 90.7% (117/129 ) ] . 117 cases with abnormal bronchial arteries were confirmed by both MDCT and DSA via femoral artery and 4 cases did not detected any abnormal arteries by both methods. The coincidence rate of two methods was 91.0% (121 /133) . MDCT and DSA via femoral artery showed the similar origins of abnormal bronchial arteries. The coincidence rate of two methods was 100% .
Conclusions  There is a high coincidence rate betweenMDCT and DSA in detecting bronchial artery abnormalities. MDCT shows the origins of abnormal vessels clearly which could be a fist-choice of routine imagination for interventive operation.
