AIMS The aim of this review was to define the place of stress echocardiography in the context of perfusion scintigraphy for the detection of coronary artery disease (CAD) and the assessment of cardiac risk. Stress echocardiography has the benefits of widespread availability, relatively low cost, portability, absence of radiation, and the determination of the ischaemic threshold. However, the ec...

BACKGROUND Non-invasive cardiological methods have been used for the identification of myocardial damage in Chagas disease. OBJECTIVE To verify whether the rest/stress myocardial perfusion scintigraphy is able to identify early myocardial damage in the indeterminate form of Chagas disease. METHODS Eighteen patients with the indeterminate form of Chagas Disease and the same number of normal ...

A known case of nephrotic syndrome aged 32 months was admitted to ICU because of loss of consciousness. In physical exam he had tachycardia, tachypnea and hypotension. Lab data showed metabolic alkalosis and hypoxia. In CXR, vascular cut off was seen in right lung and perfusion lung scan showed absence of perfusion in the right lung.Treatment was started with heparin and streptokinase, bu...

UNLABELLED The myocardial perfusion scintigraphy acquisition and analysis present some technical differences in the rare dextrocardia cases. Here we report a case of a 38 year-old woman with dextrocardia who had been applied myocardial perfusion scintigraphy. Presented case showed that the thoracic and abdominal organs had a mirror image with situs inversus totalis type dextrocardia. The incide...

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 Pulmonary embolism is a common clinical disorder that is associated with high morbidity and mortality if untreated. It is important to confirm or rule out the diagnosis in patients with clinical suspicion of the disease. PURPOSE To evaluate various diagnostic strategies for excluding pulmonary embolism. DATA SOURCES MEDLINE (1966 to February 2003), EMBASE, and DARE; study investi...

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...
