| Outline of Final Research Achievements |
Evaluation of dynamic cardiac motion is available by four-dimensional (4D) cardiac CT, but it causes higher radiation dose in the breast and lung because it needs all cardiac-phase CT data. We applied the new technique of iterative CT image reconstruction on 4D cardiac CT, resulting in low-radiation dose 4D cardiac CT. This new technique made it possible to observe the dynamic movement of the heart before and after the cardiac surgery. This method is useful especially for the off-pump coronary artery bypass grafting surgery, and the surgeons perform preoperative simulation. Also, it is useful for post-operative evaluation of graft patency. The 4D cardiac CT with lower radiation dose is helpful for safe and appropriate patient management with coronary artery disease.
