The 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 کاملReverse 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...
متن کاملOptimisation of Simultaneous Tl-201/Tc-99m Dual Isotope Reconstruction with Monte-Carlo-Based Scatter Correction
Simultaneous Tl-201/Tc-99m dual isotope myocardial perfusion SPECT is seriously hampered by down-scatter from Tc-99m into the Tl-201 energy window. This paper presents and optimises the ordered-subsets-expectation-maximisation-(OS-EM-) based reconstruction algorithm, which corrects the down-scatter using an efficient Monte Carlo (MC) simulator. The algorithm starts by first reconstructing the T...
متن کاملStress thallium-201/rest technetium-99m sequential dual isotope high-speed myocardial perfusion imaging.
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 کاملDual-isotope SPECT using (99m)Tc-hydroxymethylene diphosphonate and (201)Tl-chloride to assess mandibular invasion by intraoral squamous cell carcinoma.
UNLABELLED We examined mandibular invasion of intraoral squamous cell carcinoma by simultaneous bone and tumor dual-isotope SPECT using (99m)Tc-hydroxymethylene diphosphonate ((99m)Tc-HMDP) and (201)Tl-chloride ((201)Tl) and by CT. METHODS Early and delayed simultaneous bone and tumor dual-isotope SPECT and CT were performed on 39 patients suspected of having tumor invasion of the mandible by...
