ATP-Loading 201Tl Myocardial SPECT for the Detection of Ischemic Heart Disease.

detection of undiagnosed ischemic heart disease in hemodialysis patients using myocardial perfusion imaging

conclusions the prevalence of undiagnosed ihd in the hd patients was considerable. we, therefore, suggest that ihd be assessed in hd patients, especially those at high risk due to positive family history of cad, hypertension, left ventricular hypertrophy, diabetes mellitus, kt/v < 1.2, low ferritin levels, and high levels of intact parathyroid hormone. results sixty-nine hd patients were studie...

Compensation of Cross-Contamination in Simultaneous 201Tl/99mTc Myocardial Perfusion SPECT Imaging

Introduction: It is a common protocol to use 201Tl for the rest and 99mTc for the stress cardiac SPECT imaging. Theoretically, both types of imaging may be performed simultaneously using different energy windows for each radionuclide. However, a potential limitation is the cross-contamination of scattered photons from 99mTc and collimator X-rays into the 201Tl energy window. We used a middle en...

201Tl myocardial SPECT detects significant coronary artery disease between 50% and 75% angiogram stenosis.

UNLABELLED Coronary angiography is the "gold standard" for the diagnosis of coronary artery disease (CAD). The aim of this work was to compare 201Thallium SPECT with different coronary angiographic cutoff values. METHODS Data pertaining to 145 patients were tabulated. All patients underwent stress ECG, 201Thallium SPECT and coronary angiography. To assess the cutoff impact, two criteria for c...

تاثیر آلوپورینول بر رویoutcome بیماران ischemic heart disease بستری در ccu

چکیده مقدمه: بیماری های ایسکمیک قلب با ویژگی کاهش خون رسانی به ماهیچه قلب، به علت بیماری های عروق کرونر از جمله آترواسکلروز ایجاد می شود. از افزایش فعالیت گزانتین اکسیداز نیز منجر به عدم کارایی عروق در خون رسانی به عضله ی قلب و ایجاد انواع ایسکمی و آسیبهای بافتی و عروقی می شود. به نظر می رسد، داروهای مهارکننده گزانتین اکسیداز از طریق افزایش شرب بافتی در بهبود علائم بیماری های ایسکمیک قلب موثر ...
