Prospectively ECG Gated CT pulmonary angiography versus helical ungated CT pulmonary angiography: Impact on cardiac related motion artifacts and patient radiation dose
European Journal of Radiology, 08/21/2012
Clinical Article
Shuman WP et al. – Compared to routine helical ungated CT pulmonary angiography (CTPA), prospectively ECG gated CTPA may result in less cardiac related motion artifact in lung segments adjacent to the heart and significantly less patient radiation dose.
