Development of Digital Myocardial Phantom to Evaluate Software for Gated SPECT

Development of Digital Myocardial Phantom to Evaluate Software for Gated SPECT

Background: Real cardiac phantoms are often used to assess the performance of software for gated single-photon emission computed tomography(SPECT). However, these phantoms have disadvantages in that they are not very similar to actual hearts and setting a perfusion defect is not easy. To overcome these problems, we developed a digital myocardial phantom, named%Myo-Simu'. The aims of this study ...

Determination of optimum filter in myocardial SPECT: A phantom study

Background: In myocardial perfusion SPECT imaging, images are degraded by photon attenuation, the distance-dependent collimator, detector response and photons scatter. Filters greatly affect quality of nuclear medicine images Materials and Methods: A phantom simulating heart left ventricle was built. About 1mCi of 99mTc was injected into the phantom. Images were taken from this phantom. Some fi...

Development of quantification software using model-based segmentation of left ventricular myocardium in gated myocardial SPECT

Gated myocardial single photon emission computed tomography (SPECT) is being used for the diagnosis of coronary artery diseases. In this study, we developed new software for the quantification of volumes and ejection fraction (EF) on the gated myocardial SPECT data using a cylindrical model. Volumes and EF by developed software were validated by comparing with those quantified by quantitative g...

Evaluation of myocardial perfusion and function after kidney transplantation by Gated SPECT myocardial perfusion scintigraphy

Introduction: The aim of this study was to evaluate the effect of successful kidney transplantation (KT) on myocardial perfusion and left ventricular function by both qualitative (visual) interpretation and semiquantitative parameters, using myocardial perfusion scintigraphy with gated-single photon emission computed tomography (gated-SPECT) in patients suffering from end-stage renal disease. ...
