Myocardial perfusion imaging or scanning (also referred to as MPI or MPS) is a nuclear medicine procedure that illustrates the function of the heart muscle . [ 1 ] It evaluates many heart conditions, such as coronary artery disease (CAD), [ 2 ] hypertrophic cardiomyopathy and heart wall motion abnormalities.
The area of dysfunction should also maintain normal perfusion, detected via Positron Emission Tomography, echocardiography with contrast, and/or thallium scintigraphy in order for a diagnosis of myocardial stunning to be considered. [1] However, there are many practical challenges to diagnosing myocardial stunning using these methods.
Houshmand also treats patients who want “Barbie Botox,” which is Botox injected into trapezius muscles in the back. The procedure went viral online for its ability to elongate and soften the ...
Cardiac magnetic resonance imaging perfusion (cardiac MRI perfusion, CMRI perfusion), also known as stress CMR perfusion, [1] is a clinical magnetic resonance imaging test performed on patients with known or suspected coronary artery disease to determine if there are perfusion defects in the myocardium of the left ventricle that are caused by narrowing of one or more of the coronary arteries.
Imaging at 3T field strength offers greater signal to noise ratio which can be traded for improved temporal or spatial resolution – which is of greatest utility in first-pass perfusion studies. [28] However, greater capital costs and effects of off-resonance artefact on image quality mean that many studies are routinely performed at 1.5T. [29]
Botulinum toxin, or botulinum neurotoxin (commonly called botox), is a neurotoxic protein produced by the bacterium Clostridium botulinum and related species. [24] It prevents the release of the neurotransmitter acetylcholine from axon endings at the neuromuscular junction, thus causing flaccid paralysis. [25]
Myocardial perfusion imaging (MPI) is a form of functional cardiac imaging, used for the diagnosis of ischemic heart disease. The underlying principle is, under conditions of stress, diseased myocardium receives less blood flow than normal myocardium. MPI is one of several types of cardiac stress test.
