Abstract：Objective To explore the image quality of pulmonary DSA, and summarize the quality control measures, further improving image quality. Methods Analysis of 88 patients with pulmonary DSA images was carried out by subjective evaluation and statistics, thus to determine the impact factors of pulmonary DSA image quality. Results Pulmonary DSA image quality is affected by many factors, images quality was relatively low, closely related with action and the way of the patient's breath-hold, photography filtration, the timing and frequency of the image acquisition, the catheter tip location and the concentration of the contrast agent and the rate of total. Conclusion To obtain a good pulmonary digital subtraction angiography images, quality control measures should be completely considered.
