OBJECTIVE To evaluate the prevalence of myocardial perfusion abnormalities and the possible association between myocardial perfusion defects and traditional coronary artery disease (CAD) risk factors as well as systemic lupus erythematosus (SLE) related risk factors. PATIENTS AND METHODS Female patients with SLE, disease duration >5 years, age 18-55 years, who had used steroids for at least o...

BACKGROUND Cardiovascular disease is the leading cause of death after kidney transplant. Screening for coronary artery disease is integral to pretransplant evaluation, although the relative performance of different tests is uncertain. STUDY DESIGN Systematic review of diagnostic test accuracy studies using hierarchical summary receiver operating characteristic analysis. SETTING & POPULATION...

BACKGROUND Adenosine-assisted transthoracic Doppler-derived coronary flow reserve (TDE-CFR) reflects coronary vascular function. The prognostic and incremental value of left anterior descending coronary artery TDE-CFR above myocardial perfusion scintigraphy in patients with suspected myocardial ischemia has not yet been studied. METHODS AND RESULTS Three hundred seventy-one patients (mean age...

Myocardial perfusion scintigraphy (MPS) is the only widely available method of direct assessment of myocardial perfusion. It involves intravenous injection of small amounts of a radioactive tracer at peak stress, followed by imaging of the heart with a gamma camera. There are three commercially available tracers: thallium-201 and two technetium-labelled tracers, sestamibi and tetrofosmin. All t...

BACKGROUND This study was performed to compare Tl-201 myocardial perfusion single photon emission computed tomography (SPECT) with planar scintigraphy in the diagnosis of coronary artery disease (CAD). METHODS Retrospectively, 240 of 3262 patients, with exercise-redistribution Tl-201 myocardial perfusion scintigraphy performed between January 1990 and October 1997, were analyzed to compare Tl...

currently, myocardial ti-201 scintigraphy is most often performed in conjunction with exercise stress testing in patients with suspected or known cad. stress thallium tests were performed for 156 patients with and without old myocardial infarctions complaining of chest pain. all of them underwent contrast coronary angiography. perfusion defects were mostly manifested as reversible defects (r). ...

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 ...

Material and Methods Current study was conducted in large accredited academic institute serving as a tertiary care centre in the city of Mumbai, India. Study was done in Department Of Nuclear Medicine by performing myocardial perfusion scintigraphy in all cases. Patients with CKD with or without dialysis are at a higher risk of ischaemic heart disease due to multiple risk factors associated wit...
