Introduction: Many patients have only diastolic dysfunction without any abnormality in systolic function. We compared cardiac diastolic parameters obtained by gated myocardial perfusion SPECT (Gated SPECT) with those evaluated by echocardiography. Methods: Forty-nine patients (aged 37-85 years, 19 males and 30 women) underwent Gated SPECT and echocardiogr...

conclusions gated spect mpi has a good correlation with echocardiography for the measurement of left ventricular ef, edv, and esv in patients with severe heart failure. however, the absolute values of these functional parameters from echocardiography and gated spect mpi measured with different software packages should not be used interchangeably. results a good correlation was found between ech...

introduction:patients with the coronary slow flow phenomenon (scf) frequently experience angina episodes. the purpose of this study was to determine efficacy of nicorandil in myocardial perfusion in patients with scf. methods: twenty patients (50.85 ± 12.96 y) with scf were studied.  we evaluate coronary slow flow according to protracted thrombolysis in myocardial infarction (timi) frame count....

fixed myocardial defects in both stress and rest images, could be artifactual as a result of soft tissue attenuation. to increase specificity and identify the false positive results, we used gated technique to evaluate the wall motion and wall thickening as an index to differentiate real ischemic lesions from artifactual defects. 93 patients were studied. in 46 patients (48.8%) fixed perfusion ...

introduction: the purpose of this study is to assess the integrated role of scintigraphy by tc99m mibi in diagnosis of parathyroid adenoma and its impacts on the myocardium, and to evaluate whether myocardium perfusion gated spect study could be a complementary routine workup for patient with positive parathyroid adenoma on tc99m mibi parathyroid scan. methods: rest myocardium perfusion gated s...

Introduction:Gated myocardial perfusion SPECT has diagnostic and prognostic values in coronary artery disease (CAD). We tried to determine prognostic values of the left ventricular perfusion & functional indices as well as transient left ventricular dilation (TID) derived from gated myocardial perfusion SPECT. Methods: 1820patients who underwent gated myo...

OBJECTIVE The objective of this study was to investigate predictor variables at the moment of normal stress-rest myocardial perfusion gated SPECT for indication of a second gated SPECT. MATERIAL AND METHODS A prospective, single center cohort study was conducted. We evaluated 2326 consecutive patients (age 63.6 ± 13 years, 57.3% females) without perfusion defects and with normal left ventricu...

UNLABELLED Electrocardiographically (ECG) gated myocardial SPECT with (99m)Tc-tetrofosmin has been used widely to assess left ventricular (LV) function. However, the accuracy of variables using ECG gated myocardial SPECT with beta-methyl-p-(123)I-iodophenylpentadecanoic acid (BMIPP) has not been well defined. METHODS Thirty-six patients (29 men, 7 women; mean age, 61.6 +/- 15.6 y) with ischem...
