Reverse redistribution pattern in rest Tl-201 and stress Tc-99m SPECT in patients undergoing coronary interventions.
To cite: Matsumoto N, Yoda S, Nagao K, et al. BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2014204325 DESCRIPTION A reverse redistribution pattern in rest thallium-201 (Tl)/stress technetium-99 m (Tc) tetrofosmin single photon emission CT (SPECT) is confusing. We present a myocardial perfusion SPECT in a 40-year-old patient undergoing coronary intervention in t...

OBJECTIVES Our purpose was to describe a novel, rapid stress thallium-201 (Tl-201)/rest technetium-99m (Tc-99m) agent myocardial perfusion imaging (MPI) protocol (Tl/Tc) with a high-speed MPI scanner and to compare this protocol with a standard rest/stress Tc-99m agent protocol (Tc/Tc) with respect to image quality and radiation dosimetry. BACKGROUND Recent advances in gamma camera technology...
متن کاملReverse redistribution on exercise-redistribution (201)Tl SPECT in chronic ischemic dysfunction: predictive of functional outcome after revascularization?
UNLABELLED This study analyzed the incidence and clinical significance of reverse redistribution (RR) on stress-redistribution (201)Tl SPECT studies in patients with poor left ventricular function and tested the hypothesis that the RR phenomenon could be caused by artifacts. METHODS Seventy-three consecutive patients with chronic coronary artery disease and left ventricular dysfunction (eject...
متن کاملThe value and throughput of rest Thallium-201/stress Technetium -99m sestamibi dual-isotope myocardial SPECT.
Myocardial perfusion scintigraphy is an established method in cardiology for the diagnosis and evaluation of coronary artery disease (CAD). Thallium-201 and Tc-99m sestamibi myocardial perfusion imaging has been widely accepted as non-invasive diagnostic procedure for detection of CAD, risk stratification and myocardial viability assessment. But, standard Tl-201 redistribution and same day or 2...
متن کاملLessons from the Tc-99m shortage: implications of substituting Tl-201 for Tc-99m single-photon emission computed tomography.
BACKGROUND In 2009, the Chalk River nuclear reactor closed for repairs that led to a critical shortage of technetium-99m (Tc-99m). Several centers used thallium-201 (Tl-201) as an alternative radiotracer for myocardial perfusion imaging. Because Tl-201 is considered by many as a suboptimal radiotracer, we sought to understand the impact of using Tl-201 (during the Tc-99m shortage) on downstream...
