Low tube voltage prospectively ECG-triggered coronary CT angiography: a systematic review of image quality and radiation dose

摘要

Objective: This study aimed (1) to perform a systematic review on scanning parameters and contrast medium (CM) reduction methods used in prospectively electro-cardiography (ECG-triggered low tube voltage coronary CT angiography (CCTA), (2) to compare the achievable dose reduction and image quality and (3) to propose appropriate scanning techniques and CM administration methods.
