In hepatic digital subtraction angiography, artifacts caused by diaphragmatic motion can interfere with the correct diagnosis of hepatic lesions. This article describes the feasibility of using the exhalation holding method in reducing diaphragmatic motion artifacts in hepatic DSA. The authors compared respiratory holding methods in 30 patients who underwent hepatic DSA. They performed a blind comparison of images to assess diaphragmatic motion artifacts. Results showed the images obtained by the exhalation holding method were superior to those obtained by the inhalation holding method in 20 out of 30 series (66.7%).
