Evaluation of the potential impact of reconstruction method on dyssynchrony parameters derived by phase analysis of gated-SPECT MPI: Comparison of two quantitative software
Introduction: Gated SPECT myocardial perfusion scanning has new capabilities in addition to its main applications such as left ventricular dyssynchrony using phase analysis. Phase analysis has been investigated through various software including Emory Cardiac Toolbox (ECTb) and Quantitative Gated SPECT (QGS). The aim of this study is to evaluate the effect of reconstruction par...
متن کاملEvaluating the Effect of Injected Dose of 99mTc- MIBI on the Quantitative Parameters of Myocardial Perfusion Imaging
Background: 99mTc-MIBI cardiac perfusion scanning is recognized as a clinically useful method in evaluating coronary artery disease. By the implementation of new imaging techniques and systems, it seems possible to obtain high-quality images with a lower dose of radiopharmaceuticals. The purpose of this study was to evaluate the effect of injection dose of 99mTc-MIBI on quantitative parameters ...
متن کاملDetermination of normal ranges of regional and global phase parameters using gated myocardial perfusion imaging with Cedars-Sinai’s QGS software
Introduction: Myocardial perfusion imaging using gated SPECT and phase analysis is an effective tool in evaluation of mechanical dyssynchrony. The purpose of this study was to determine the normal ranges of global and regional phase parameters. Methods: A total of 100 patients with normal resting and stress electrocardiograms, low pretest likelihood for c...
متن کاملDifferential diagnosis of pancreatic cystic masses with the quantitative analysis of spectral CT imaging: Initial results
Background: To retrospectively evaluate whether quantitative information derived from spectral imaging can improve the differential diagnosis of pancreatic cystic masses including pancreatic solid pseudopapillary epithelial neoplasms (SPENs), mucin- producing cysts and pseudocysts. Materials and Methods: From June 2015 to October 2017, 56 patients (22 pseudocysts, 18 mucin-producing cysts and 1...
متن کاملScanning impedance microscopy (SIM): A novel approach for AC transport imaging
Scanning Impedance Microscopy (SIM) is one of the novel scanning probe microscopy (SPM) techniques, which has been developed to taking image from sample surface, providing quantitative information with high lateral resolution on the interface capacitance, and investigating the local capacitance–voltage (C–V) behavior of the interface and AC transport properties. The SIM is an ordinary AFM equip...
متن کاملQuantitative phase measurements using optical quadrature microscopy.
Imaging of phase or optical path length is becoming more important with the development of better imaging systems, computational algorithms, faster computers, and a greater interest in the imaging of transparent objects. Early phase imaging involved qualitative imaging of phase gradients. New computational algorithms can be used to extract some quantitative phase imaging from these techniques. ...
