Objective: Thallium-201-chloride myocardial SPECT imaging accounts for about one-third of
our daily nuclear medicine imaging workload. However, cancellation of imaging …

Purpose This study evaluates not only the clinical usefulness but also the problems in
attenuation correction for thallium-201 (Tl-201) myocardial SPECT by means of …

Data Acquisition To determine the correction factors and evaluate the tech nique, both
phantom and patient studies were performed. Data were acquired using a GE 400 AC/T …

P@(x, y, 0). For the purposeof thiswork, f@(x, y, 0) andf@(x, y, 0) will be used to quantify the
relative contamination rates between the transmission windows of@ Amand@ Tcwith the …

Background To define the physical and clinical reproducibility of 201 Tl myocardial perfusion
SPECT (MPS), this study assesses the variation between two repeated rest 201 Tl MPS with …

During the past several years, there has been considerable concern expressed in both the
medical literature and the lay press about the dose of radiation from medical imaging …

Abstract Objective IQ-SPECT (Siemens AG, Munich, Germany) is a highly sensitive single-
photon-emission computed tomography (SPECT) myocardial perfusion imaging (MPI) …

The aim of this study was to evaluate the clinical usefulness of attenuation and scatter
correction (AC, SC) on a 201Tl myocardial single-photon emission computed tomography …

This study compared attenuation compensated, myocardial SPECT ¡ magesreconstructed
from 180Âand 360Âdata to determine ifeither data acquisition method might yield improved …

This study evaluates the usefulness of attenuation correction on regional myocardial tracer
distributions defined by Thallium-201 myocardial SPECT images obtained from cardiac …
