posted by Sebastian Leschka, M.D. | Jan 26, 2011
Sebastian Leschka, M.D.

To compare image quality and radiation dose of high-pitch CTA of the aortic valve-aortic root complex with and without prospective ECG-gating compared to a retrospectively ECG-gated standard-pitch acquisition. Read more

Prospective and retrospective ECG-gating for CT coronary angiography perform similarly accurate at low heart rates

posted by Hatem Alkadhi, M.D., M.P.H., E.B.C.R. | Nov 22, 2010
Hatem Alkadhi, M.D., M.P.H., E.B.C.R.

Prospectively ECG-gated CTCA yields similar image quality, performs as accurately as retrospectively ECG-gated CTCA in patients having heart rates Read more
