1. Iterative reconstruction algorithms for CT are now widely used in clinical examinations. We demonstrate their effectiveness at cardiac CT. 2. There are various effective techniques to use iterative reconstruction algorithms for cardiac CT. They can improve the image quality and diagnostic performance, and reduce the radiation exposure and contrast material dose.

1. Principles of iterative reconstruction algorithms - First-generation iterative reconstruction - Hybrid iterative reconstruction - Full iterative reconstruction 2. Combined use with low tube-current techniques - Reduction in the radiation dose - Protocol optimization 3. Combined use with low tube-voltage techniques - Reduction in radiation exposure and contrast material dose - Protocol optimization 4. Combined use with a high-resolution kernel - Improved coronary in-stent visualization 5. Application in patients with various conditions - Obese patients - Pediatric patients - Patients with renal dysfunction - Patients with difficult venous access
