CT Myocardial Perfusion Imaging
American Journal of Roentgenology, 2015OBJECTIVE. CT myocardial perfusion imaging is rapidly becoming an important adjunct to coronary CT angiography for the anatomic and functional assessment of coronary artery disease with a single modality. Existing techniques for CT myocardial perfusion imaging include static techniques, which provide a snapshot of the myocardial blood pool, and dynamic

Myocardial Perfusion Scintigraphy
Archives of Internal Medicine, 1980Recent progress in diagnostic cardiology has centered around noninvasive methods 1,2 ; among these, echocardiography and myocardial scintigraphy have developed most rapidly. 3-6 Probably most prominent among the diverse scintigraphic methods is relative myocardial perfusion imaging.

Sinusoidal Myocardial Perfusion
Archives of Surgery, 1973Seventeen dogs with evolving myocardial infarctions were treated with an internal mammary artery implant in the ischemic area of the heart. The survival rate in these dogs was significantly higher than that in a control group. Improved survival was probably due to flow of arterial blood from the implant into the ischemic region.

Quantitative myocardial perfusion SPECT
Journal of Nuclear Cardiology, 1998In recent years, there has been much interest in the clinical application of attenuation compensation to myocardial perfusion single photon emission computed tomography (SPECT) with the promise that accurate quantitative images can be obtained to improve clinical diagnoses.

Contribution of myocardial contractility to myocardial perfusion
American Journal of Physiology-Heart and Circulatory Physiology, 1979Myocardial contractility in open-chest anesthetized (sodium pentobarbital) dogs was varied while ventricular pressure, coronary perfusion pressure, and coronary tone were held constant. Under those conditions, changes in regional blood flow should reflect changes only in intramyocardial compression related to the altered inotropic state.

Myocardial Perfusion Scintigraphy
2016Abstract Acute chest pain is one of the most common presenting complaints in the emergency department. While chest pain is not specific for underlying coronary artery disease, exclusion of acute coronary syndrome, defined as myocardial infarction or unstable angina, is a critical component of any clinical diagnostic algorithm. In reality,

[Myocardial perfusion scintigraphy].
La Tunisie medicale, 2003The aim of this review was to recall the relevance of the myocardial perfusion scintigraphy procedure in the diagnosis of coronary artery disease. Myocardial perfusion scintigraphy is undergone after treadmill exercise or pharmacological stress by infusion of Dipyridamole.

Myocardial perfusion scintigraphy
British Journal of Cardiac Nursing, 2010This article reviews the role of myocardial per fusion scintigraphy (MPS), a non-invasive cardiac imaging technique, in the diagnosis, assessment and management of coronary heart disease. An injection of a small amount of radioactive tracer and a gamma camera are used to produce images of blood flow to the myocardium after stress (exercise or ...

Thallium (201Tl) is a metallic element with a biological behaviour similar to potassium. It is generated in cyclotrons, and its T1/2 is 73 h. It decays by electron capture and its more important emission is X rays, with an energy of 69 to 83 keV at the lower end of the spectrum range that can be detected by a scintillation camera.
