Left ventricular myocardial cellular perfusion against the background of cardiac contractility modulation in patients with heart failure and atrial fibrillation

Российский кардиологический журнал, 2021
Aim. To assess the effect of cardiac contractility modulation (CCM) in patients with heart failure (HF) and atrial fibrillation (AF) on left ventricular (LV) myocardial cellular perfusion using perfusion single photon emission computed tomography (SPECT).

Dynamic CT myocardial perfusion imaging [PDF]

European Journal of Radiology, 2016
Non-invasive cardiac imaging has rapidly evolved during the last decade due to advancements in CT based technologies. Coronary CT angiography has been shown to reliably assess coronary anatomy and detect high risk coronary artery disease. However, this technique is limited to anatomical assessment, thus non-invasive techniques for functional assessment

Dynamic CT myocardial perfusion imaging

Journal of Cardiovascular Computed Tomography, 2020
Cardiac CT offers several approaches to establish the hemodynamic severity of coronary artery obstructions. Dynamic myocardial perfusion CT (MPICT) is based on serial CT imaging to measure the inflow of contrast medium into the myocardium and calculate absolute measures of myocardial perfusion. This review describes the MPICT acquisition protocol, post-

Image Registration in Myocardial Perfusion MRI [PDF]

2005 IEEE Engineering in Medicine and Biology 27th Annual Conference, 2005
In clinical first-pass myocardial perfusion studies, physiological and patient motions are inevitable. Such motions impair the sensitivity and reliability in assessing myocardial perfusion abnormalities. The current study aims to correct the misregistration of myocardium during first-pass perfusion imaging by using a normalized mutual information ...
