Left ventricular function in response to dipyridamole stress: head-to-head comparison between 82Rubidium PET and 99mTc-sestamibi SPECT ECG-gated myocardial perfusion imaging

Abstract

Rb summed rest (SRS), stress (SSS) and difference (SDS) scores, and LV end-diastolic (EDV) and end-systolic (ESV) volumes and left ventricular ejection fraction (LVEF) were compared. Results Bland-Altman analysis showed that with increasing ESVand EDV the difference between the two perfusion tracers increased both at rest and post-stress. The mean difference in EDV and ESV between the two perfusion tracers at rest could both be independently explained by the 82 Rb SDS and the sestamibi SRS. The combined models explained approximately 30% of the variation in these volumes between the two perfusion tracers (R 2 = 0.261, p = 0.005; R 2 = 0.296, p < 0.001, for EDVand ESV respectively). However, the mean difference in LVEF between sestamibi and

Preconcentration and Separation of Rubidium from Salt Lake Brine by Ammonium Phosphomolybdate - Polyacrylonitrile (AMP-PAN) Composite Adsorbent

“…Rare alkaline metal rubidium and its compounds are followed with interest by more and more scholars in recent years, because of the widely used in electronic technology, catalyst, medicine, chemical engineering and other fields . And rubidium ion exists in natural sources like mine, geothermal water, spring water, underground water, oil and gas field water and salt lake brine .…”
