Improved Visualization of Heart Valves With 4D-CT Using a Novel Motion Correction Algorithm

OBJECTIVE: Motion artifacts remain a limitation of cardiac CT when assessing both native and prosthetic heart valves, particularly during phases of rapid motion. This may lead to reduced image quality, potentially impairing the evaluation of valvular movement and pathology. The p...

Improving image quality by reducing breathing artifacts in CT of patients early after coronary artery bypass graft surgery

Abstract The purpose of this study was to evaluate whether a misalignment correction algorithm reduces artifacts from breathing in patients undergoing computed tomography angiography (CTA) early after coronary artery bypass graft (CABG) surgery. In this retrospective study, conse...
