A health care provider puts sticky patches called electrodes on your chest and sometimes the arms and legs. This may be achieved with improvement in coincidence time resolution (lower than 100 ps) through new PET detector designs, and some day even crossing the 10 ps, which will increase the performance of time-of-flight PET dramatically, resulting in a better signal-to-noise ratio of the activity measurement (e.g., F-18 Flurpiridaz), improving the reconstruction process and rendering quantifying the endocardial-to-epicardial distribution of myocardial blood flow achievable and attainable. Normal heart Rate is 60-180 and the rhythm is sinus rhythm. MPI plays a key role in diagnosing cardiovascular disease, establishing prognosis, assessing the effectiveness of therapy, and evaluating viability. 8.

Unlike the classical Luria-Delbrck fluctuation test, and motivated by recent work on drug . A coronary stenosis is detected when a myocardial segment takes up the nuclear tracer at rest, but not during cardiac stress. When myocardial segments are between anatomical boundaries of major coronary artery vascular territories, such as the inferolateral region, it is often underestimated by global or vascular territory hyperemic myocardial blood flow values.

The development of single photon emission computed tomography (SPECT) led to improved assessments of myocardial perfusion, and the use of electrocardiographic gating made accurate measurements of ventricular wall motion, ejection fractions, and ventricular volumes possible. What is nuclear medicine myocardial perfusion stress test? At the present time, there are multitude of confounding factors and/or variables that may significantly impact the quantitative myocardial blood flow value. Ask your health care provider if you can take your medicines before the test. Also, they suggest that the term anteroseptal describes the interior wall of the extreme MI. Given that uptake and retention of single photon emission computed tomography (SPECT) myocardial perfusion tracers, such as thallium, sestamibi, and tetrofosmin, reflect intact sarcolemmal Na-K ATPase or mitochondrial function, it would be anticipated that there would be a nearly linear relationship with the percentage of normal (viable) myocardium in dysfunctional regions.9,10 Indeed, several studies have shown a graded relationship between percent regional radiotracer uptake or percent transmural hyperenhancement on cardiac magnetic resonance and recovery of function after revascularization (Figure2).11 Irrespective of the imaging modality applied, the data suggest that recovery of function after revascularization is a continuum and is coupled to the ratio of the admixture of scarred and viable myocardium within the dysfunctional regions. It is also possible that you feel discomfort, which may include; There may be several questions that you want to ask your doctor before the test and also want to tell you about your condition and the drugs you are already using.
