WebMar 1, 2010 · The short half-life requires rapid image acquisition shortly after tracer administration, which can reduce a total study time. Because of its short half-life, 82 Rb presents limited radiation exposure for patients (5.5 mSv for 60 mCi) [22]. Thus, a stress and rest 82 Rb study has 11.0 mSv of total body radiation exposure.
82 Rb also has an advantage in that it has a very short half-life which results in much lower radiation exposure for the patient. This is especially important as the use of myocardial imaging increases in the medical field. See more Rubidium-82 ( Rb) is a radioactive isotope of rubidium. Rb is widely used in myocardial perfusion imaging. This isotope undergoes rapid uptake by myocardiocytes, which makes it a valuable tool for identifying myocardial See more Rubidium-82 is produced through beta plus decay from its parent nucleus, strontium-82. The generator contains accelerator produced Sr … See more Rubidium is rapidly extracted from the blood and is taken up by the myocardium in relation to myocardial perfusion, which requires energy for … See more • Efseaff, M; Klein, R; Ziadi, MC; Beanlands, RS; deKemp, RA (2012). "Short-term repeatability of resting myocardial blood flow measurements using rubidium-82 … See more In 1953, it was discovered that rubidium carried a biological activity that was comparable to potassium. In 1959, preclinical trials showed in dogs that myocardial uptake of this radionuclide was directly proportional to myocardial blood flow. In 1979, Yano … See more Mechanism of action Rb has activity very similar to that of a potassium ion (K ). Once in the myocardium, it is an active participant in the sodium-potassium exchange pump of cells. It is rapidly extracted by the myocardium … See more WebSep 1, 2013 · The short half-life of 82 Rb means reduced radiation exposure for patients. In our institution, the estimated effective dose for 2 × 1110 MBq 82 Rb is 2.8 mSv (using published dosimetry data 15 and International Commission on Radiological Protection 103 tissue weighting factors).
