Lung Image Quality with 320-row Wide-volume CT Scans: The Effect of Prospective ECG-gating and Comparisons with 64-row Helical CT Scans

Lung image quality of ECG-gated WV scans, which do not require any additional radiation exposure, is better than that of non-ECG-gated 64-row helical scans. Non-ECG-gated 320-row WV scans are comparable or slightly superior to non-ECG-gated 64-row helical scans.
