It is of value to determine the amount of viable myocardial tissue in patients suffering from chronic coronary artery disease and ventricular dysfunction. Having the capability of evaluating both myocardial perfusion and function, simultaneously, myocardial scanning by ECG-Gated is an appropriate method for this purpose. The aim of this study was to compare the results of myocardial perfu...

OBJECTIVE Since twenty-four-hour imaging by Tl-201 myocardial perfusion scintigraphy has been introduced as an effective additional procedure, the aim of this study was to compare this method's result with only rest redistribution procedure in the diagnosis of myocardial viability. METHODS Thirty patients (Seven female, 23 male; mean: 59.8 ± 10.7, 55.8-63.8 years old) with diagnosis of corona...

OBJECTIVE To evaluate the discriminatory value and compare the predictive performance of six non-invasive tests used for perioperative cardiac risk stratification in patients undergoing major vascular surgery. DESIGN Meta-analysis of published reports. METHODS Eight studies on ambulatory electrocardiography, seven on exercise electrocardiography, eight on radionuclide ventriculography, 23 o...

Modern imaging techniques occupy an important place in the diagnosis, selection of treatment and prognosis patients with coronary artery disease. Hybrid is a combination two sets diagnostic data that complement enhance each other by comparing anatomical functional characteristics. As rule, hybrid synergistic, is, more powerful, since addition new information leads to increase sensitivity specif...

dextrocardia is a cardiac positional anomaly in which the heart is located in the right hemithorax with its base-to-apex axis directed to the right and caudad. situs inversus is an autosomal recessive disorder that causes organs in the chest and abdomen to be positioned in a mirror image from their normal position. dextrocardia may occur in isolation or as part of situs inversus. similarly, sit...

Different software tools for quantification of myocardial perfusion SPECT (MPS) studies are routinely used. Several perfusion parameters can be computed automatically.  Interpretation of the MPS should start with visual inspection of the rotating planar images, visual analysis of reconstructed SPECT slices and then quantitative analysis to confirm the visual impression. Quantification should be...

introduction:we evaluated the performance of muscle perfusion scan (mps) to assess muscle perfusion reserve (mpr) for prediction of incident diabetic foot ulcerations (dfu). methods: we recruited 41 diabetic patients without any history of dfu. five mci 99mtc-mibi was injected intravenously during repetitive dorsal and plantar right foot flexions. then posterior calves were imaged and the count...
