Aims and objectives
Coronary CT angiography (CCTA) has a high diagnostic sensitivity and negative exclusion value for coronary heart disease.
As a non-invasive test,
it is expected to replace invasive coronary angiography (CAG) and intravascular ultrasound.The full model iterative reconstruction (IMR) technique is a new generation of iterative reconstruction algorithm.
In theory,
its effect of reducing noise and improving image quality is superior to filtered back projection reconstruction (FBP) technology and advanced hybrid iterative reconstruction (iDose4) technology.
In the case of low radiation dose,
image noise can be significantly reduced,
and image contrast-to-noise ratio (CNR) and image quality can be improved.
Using a pulsating cardiac phantom and artificial plaques and vessels,to investigate the variability of coronary plaque burden evaluation by low-dose coronary CTA with iterative model reconstruction(IMR).
