Objective: To explore the Application of the 16-slice spiral CT testing scan technique in pulmonary angiography, in order to improve the quality of CTPA. Methods:50 CTPA in testing scan group and conventional scan group respectively were examined with GE Light speed 16-slice spiral CT. The data of al patients were transmit ed to the workstation (ADW4.2) and reconstruction. The quality of al images were evaluated by three experienced doctors using double-blind method in charge in four grades (A,B,C and bad), and the mean peak time of main Artery of al grade A were also compared. Results:Testing scan:the rate of A,B,C and bad was 90%、6%、4% and 0% respectively. conventional scan: the rate of grade A,B,C and bad was 62%、12%、22% and 4% respectively. Conclusion: Testing scan technique is superior than conventional scan in image quality of 16-slice spiral CT pulmonary angiography . Testing scan technique is good for radiographic diagnosis and remedies.
