Rubidium-82 (82 Rb) is a radioactive isotope of rubidium. 82 Rb is widely used in myocardial perfusion imaging. This isotope undergoes rapid uptake by myocardiocytes, which makes it a valuable tool for identifying myocardial ischemia in Positron Emission Tomography (PET) imaging.

By comparison with 99m Tc-SPECT, 82 Rb PET had a much better diagnostic accuracy, especially in obese patients with body mass index ≥30 kg/m 2 (85 versus 67% with SPECT) and in women with large breasts. A great advantage of …

2025年2月1日 · Rubidium Rb 82 injection is used in adults to help diagnose heart disease. It is used in a procedure called a positron emission tomography (PET) scan to help your doctor see an image of your heart. This medicine shows how much blood is getting to your heart muscle when you are resting or exercising (stressed).

Rubidium-82 chloride (Rb-82) (T 1/2 = 75 sec) is a chemical analog of Tl-201 chloride used for the assessment of coronary artery disease with PET. 19, 33 Rb-82 is produced as the daughter radionuclide of strontium-82 (Sr-82) eluted from a portable on-site generator renewed approximately monthly due to the physical half-life of Sr-82 (T 1/2 = 25 ...

Abstract Introduction Strontium-82/Rubidium-82 (82 Sr/ 82 Rb) generators are used widely for positron emission tomography (PET) imaging of myocardial perfusion. In this study, the 82 Rb isotope yield and production efficiency of two FDA-approved 82 …

Rubidium 82 (82Rb) 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...

铷-82 (Rb-82) 和铊-201 (Tl-201) 具有与钾离子 (K) 相似的活性。 两种示踪剂都是细胞钠钾交换泵的积极参与者。 它们从血液中快速提取，并在组织灌注时被细胞吸收，这需要通过 Na/K-ATP 酶为细胞吸收提供能量。

Properties and data of the isotope 82 Rb. See also: list of Rubidium isotopes. Half-life T ½ = 1.2575 (2) min (minutes) respectively 7.545 × 101 seconds s. Direct parent isotope is: 82 Sr. Nuclear isomers or excited states with the activation energy in keV related to the ground state.

Hybrid cardiac positron emission tomography/computed tomography (PET/CT) with 82 rubidium (82 Rb) is a useful clinical tool for the diagnosis of unknown or suspected coronary arterial disease (CAD) and microvascular disease, improving the understanding of the pathophysiology of disease processes thus directly impacting the therapeutic approach ...

82 Rb- PET demonstrated sensitivity and specificity of 90% and 88% for the detection of obstructive coronary disease on invasive coronary angiography (Fig. 1). 82 Rb- PET was demonstrated to have superior accuracy in comparison with 99m Tc- SPECT with both ECG-gating and attenuation correction (Mc Ardle et al ., 2012 ).
