Via the attachment of ECG leads, cardiac gating aims to find a consistent portion of the R-R interval (measured as a percentage), most commonly at the mid to end-diastolic phase (around 70% of the R-R interval) 1, where movement is at its least. For higher heart rates (>80bpm) end-systole acquisition (30-35% of R-R interval, …

Webcomponent. A low-dose CT scan (120 kV, 40 mA) was acquired for attenuation correction of PET emission data before rest acquisition. Rest Acquisition. 82Rb-chloride (1,480–1,850 MBq [40–50 mCi]) was infused intravenously from a strontium–rubidium generator as a slow bolus over 30 s, and a 2-dimensional list-mode PET scan was obtained over ... WebJun 19, 2014 · End-systolic imaging has been suggested to improve image quality during magnetic resonance coronary angiography compared to diastolic acquisitions in 14 subjects with heart rates exceeding 65 beats/minute using a 1.5 tesla (T) MR scanner , and among 10 volunteers imaged using a 3 T scanner .
WebThe algorithm retrieves the imaging data set and may ingest additional electronic medical record data such as age, sex, and body surface area (BSA). The algorithm calculates local values for LA size during diastole and systole. ... Ejection fraction (%) calculated as follows: (end-systolic volume – end-diastolic volume) / (end-systolic volume ... WebRV area change/end-systolic area, and stroke volume/end-systolic area but not TAPSE/pulmonary artery acceleration time were correlated with Ees/Ea and end-diastolic elastance. Of the surrogates, only TAPSE/PASP emerged as an independent predictor of Ees/Ea (multivariate odds ratio: 18.6; 95% CI, 0.8– 96.1; P=0.08). In receiver operating ...
