We investigate the accuracy of direct attenuation correction (AC) in the image domain for
myocardial perfusion SPECT (single-photon emission computed tomography) imaging (MPI-…

This study implicates the synthesis of lead oxide nanoparticles (PbO-NPs) in a green manner
by using the extracts of Trigonella feonumgraecum for stabilizing and capaging purposes. …

In this study after benchmarking of Monte Carlo (MC) simulation of a 6 MV linac, the simulation
model was used for estimation of tumor dose enhancement by gold nanoparticles (GNPs)…

Single-photon emission computed tomography (SPECT)-based tracers are easily available
and more widely used than positron emission tomography (PET)-based tracers, and SPECT …

Patient motion during myocardial perfusion SPECT is a common source of errors. The
extent and severity of motion artifacts have been described for filtered backprojection (FBP) …

Background With the increasing efforts to a better understanding of psychiatric diseases,
detection of brain morphological alterations is necessary. This study compared two methods—…

Introduction: QUALITY CONTROL is an important phenomenon in nuclear medicine imaging.
A Jaszczak SPECT Phantom provides consistent performance information for any SPECT …

Background. We evaluated the feasibility of outlining the body with scattered photons using
a low dose intradermal injection of the radiotracer. Patients and methods. Sixty breast cancer …

Objective (s): In recent years, the application of radiopharmaceuticals in nuclear medicine
