The purpose of this study was to evaluate the effects of IMR on image quality (IQ) and hemodynamic parameters in dynamic myocardial computed tomography perfusion (CTP) in comparison to those with filtered back projection (FBP) and hybrid iterative reconstruction (HIR).
Efficacy
1, Visual image quality in dynamic myocardial CTP among FBP, HIR and IMR.
2, Quantitative image quality (SD, SNR, CNR) in dynamic myocardial CTP among FBP, HIR and IMR.
3, Hemodynamic parameters' value and SNR of myocardial perfusion (myocardial blood flow, myocardial blood volume, mean transit time) among FBP, HIR and IMR.
