Ultrafast computed tomography techniques in cardiac disease

Ultrafast computed tomography (UFCT) with scan times in milliseconds has matured as an important diagnostic instrument since it was first introduced. Dynamic scanning can be performed virtually anywhere and the short scan times give cross-sectional images free of artifacts. These factors allow one to obtain CT studies in many different heart disorders, even in the postoperative period while the patient is on cardiopulmonary assist devices. The evaluation of coronary artery bypass graft patency remains an important use of the modality.
