The Value of 16-Slice MSCT Angiography in the Diagnosis and Treatment of Lung Cancer

Objective:To explore the value of CT pulmonary angiography with 16-slice MSCT for the diagnosis and treatment in lung cancer.Methods:28 patients with lung cancers including central type (n=18) and peripheral type (n=10) proved by operation or pathology were analyzed retrospectively.Spiral CT scanning was performed using 1mm thickness and a pitch of 0.9375,and CTA was performed.Post processing technique:MPR,MIP,SSD and VR were used.Results:All 18 cases with central lung cancer were supplied by the bronchial artery,1 case of them by the bronchial artery and intercostal artery.Of 10 cases of peripheral lung cancer,5 cases were supplied by the bronchial artery,2 cases from them by the bronchial artery and intercostal artery.In other 5 cases the supplying artery could not the determined.23 of 28 cases with lung cancer had arterial morphological changes including 15 cases of central lung cancer,and 8 cases of peripheral lung cancer.10 cases had mouse tail sign,12 cases had vascular compression and stricture,3 cases had superior vena cava stricture or occlusion.Conclusion:16-slice CTA has great value in demonstration of supplying artery of tumour and evaluating invasion of pulmonary vessels in lung cancer.
