PET Myocardial Perfusion Imaging: 82Rb SpringerLink

2019-10-13  Abstract. Rubidium 82 (82 Rb) is a positron emitter tracer, produced by the nuclear decay of Strontium-82 by electron capture via a commercially available generator.It is used for PET myocardial perfusion imaging (MPI) and quantification of myocardial blood flow (MBF) that has been shown accurate despite the limits of quantification intrinsic to non-diffusible tracers.

Simulation of Low-Dose Protocols for Myocardial

2021-8-1  Abstract. Quantification of myocardial perfusion and myocardial blood flow using 82 Rb PET is increasingly used for assessment of coronary artery disease. Current guidelines suggest injections of 1,100–1,500 MBq for both stress and rest. Reducing the injected dose avoids PET system saturation in first-pass flow images and reduces radiation

Rubidium 82 an overview ScienceDirect Topics

Rubidium-82. As a myocardial flow tracer, 82 Rb is increasingly used for the assessment of myocardial perfusion or its relative radiotracer uptake of the left ventricle during stress and rest in the evaluation of flow-limiting epicardial stenosis. 12, 16–22 Recent investigations also suggest the utility of 82

Quantification of myocardial perfusion reserve by CZT

2020-5-7  Background. We measured myocardial blood flow (MBF) and perfusion reserve (MPR) by dynamic CZT-SPECT and 82 Rb-PET in patients with suspected or known coronary artery disease (CAD) and compared the accuracy of the two methods in predicting obstructive CAD.. Methods. Twenty-five patients with available coronary angiography data underwent 99m Tc-sestamibi CZT-SPECT and 82 Rb-PET cardiac imaging.

Story of Rubidium-82 and Advantages for Myocardial

2015-9-11  Keywords: rubidium-82, myocardial perfusion, PET imaging. Go to: Introduction. The story of medical use of rubidium goes back in 1954 when Love et al. showed that the biological behavior of rubidium was comparable to the one of potassium and that its myocardial muscle uptake was proportional to blood flow in coronary arteries .

Impact of Myocardial Perfusion Imaging with PET and

Abstract. We hypothesized that PET myocardial perfusion imaging with 82 Rb (PET MPI), would reduce downstream utilization of diagnostic arteriography, compared with SPECT, in patients matched for pretest likelihood of coronary disease (pCAD). PET MPI is more accurate for assessment of impaired coronary flow reserve compared with SPECT MPI, potentially reducing the demand for subsequent

Patients were followed for the

Procedure Guideline for Myocardial Perfusion Imaging 3.3

Myocardial perfusion imaging with 13 N-ammonia follows the same protocol as described for 82 Rb. However, because of its longer physical half-life of 9.8 min, image acquisition times and temporal spacing between rest and stress radiotracer injections must be longer.
