[ 1 ] - Hepatobiliary excretion of 99mTc-EC: A potential source of mistake in the interpretation of renal scintigraphy

A 10-year-old boy with a history of bloody discoloration of urine following recent appendectomy was referred to our department for urinary leakage/fistula evaluation. A renal Technetium-99m-L,L-ethylenedicysteine (99mTc-EC) scintigraphy was performed. After injection of radiotracer, a focus of activity appeared in the supralateral part of the right kidney which was confirmed as accum...

[ 2 ] - Relationship between Baseline ECG Abnormalities and Quantitative Perfusion Parameters of Myocardial Perfusion Findings

Background: Coronary Artery Disease (CAD) is one of the major causes of mortality in most countries. Electrocardiography (ECG) and myocardial perfusion imaging (MPI) are non-invasive disgnostic tests for CAD. Finding a relationship between abnormal findings in the baseline ECG and MPI findings can be helpful in better diagnosis of CAD. Materials and Methods: The present study examined ECG of pa...

[ 3 ] - Impact of reconstruction method on quantitative parameters of 99mTc-TRODAT-1 SPECT

Introduction: Quantitative evaluation is recommended to improve diagnostic ability and serial assessment of dopamine transporter (DAT) density scans. We decided to compare the ordered subsets expectation-maximization (OSEM) with filtered back-projection (FBP), and to investigate the impact of different iteration and cut-off frequencies on SBR values. Methods</stro...

[ 4 ] - 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...

[ 5 ] - The role of myocardial perfusion SPECT in short-term cardiac prognosis of end-stage renal disease

Introduction: One of the most important causes of death in patients with end-stage renal disease (ESRD) and even after kidney transplantation is cardiovascular diseases. Thus, cardiac evaluation is of utmost importance in the management of these patients especially during preoperative work up before renal transplantation. The aim of present study is to evaluate the role of myoc...
