Semi-quantitative assessment of resting perfusion in chronic myocardial infarction
Methods We identified 19 patients who underwent regadenoson stress CMR (1.5T, Philips), had MI confirmed by late gadolinium enhancement (LGE), and underwent invasive coronary angiography within 6 months of CMR. Stress perfusion images were obtained during first pass of Gadolinium contrast agent one minute after regadenoson (0.4mg IV bolus) injection, and followed by reversal with aminophylline ...
متن کاملSemi-quantitative segmental perfusion scoring in myocardial perfusion SPECT: visual vs. automated analysis
Introduction: It is recommended that the physician apply at least a semi-quantitative segmental scoring system in myocardial perfusion SPECT. We aimed to assess the agreement between automated semi-quantitative analysis using QPS (quantitative Perfusion SPECT) software and visual approach for calculation of summed stress score (SSS), summed rest score (SRS) and summed difference score (SDS). ...
متن کاملQuantitative Assessment of Myocardial Perfusion MRI
Myocardial perfusion MRI is acquired with a T1-weighted dynamic MRI sequence. Fully quantitative analysis of myocardial perfusion MRI allows the absolute quantification of myocardial blood flow (MBF) through the use of complex mathematical modeling. There are essentially two main methods for quantification of absolute MBF: the linear time-invariant model and the compartment model. Maximized con...

متن کاملSemi-quantitative assessment of pulmonary arterial hypertension associated with congenital heart disease through myocardial perfusion imaging.
OBJECTIVE The study aimed to use myocardial perfusion imaging (MPI) as a semi-quantitative method to assess the clinical severity of pulmonary arterial hypertension (PAH) in patients with congenital heart disease (CHD). SUBJECTS AND METHODS A total of 24 patients with PAH related to CHD (PAH-CHD) who received interventional or medical treatment were included. All patients underwent physical e...
