Conclusion

Radiation dose of dual source-CCTA in heart transplant recipients can be significantly reduced by using the ECG-gated sequence technique in the systolic phase and automated tube voltage selection, compared to the ECG-gated sequence technique using a wide padding window and the conventional spiral technique, while diagnostic image quality is maintained.
