Myocardial perfusion scintigraphy [PDF]

Clinical Medicine, 2006
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.

Spatio-Temporal Modelling of Perfusion Cardiovascular MRI [PDF]

, 2010
Myocardial perfusion MRI provides valuable insight into how coronary artery and microvascular diseases affect myocardial tissue. Stenosis in a coronary vessel leads to reduced maximum blood flow (MBF), but collaterals may secure the blood supply of the ...

The relative contributions of myocardial perfusion, blood volume and extracellular volume to native T1 and native T2 at rest and during adenosine stress in normal physiology

Journal of Cardiovascular Magnetic Resonance, 2019
Background Both ischemic and non-ischemic heart disease can cause disturbances in the myocardial blood volume (MBV), myocardial perfusion and the myocardial extracellular volume fraction (ECV). Recent studies suggest that native myocardial T1 mapping can

Addressing the patient experience in myocardial perfusion scintigraphy [PDF]

, 2019
Background: Myocardial Perfusion Scintigraphy is a medical exam whose purpose is to evaluate myocardial perfusion. This examination due to their procedures can generate some anxiety in patients that can disturb the good performance of the exam.

Assessment of asymptomatic ischemic heart disease using stress myocardial perfusion imaging in patients with type 2 diabetes mellitus

Indian Heart Journal, 2018
Background: Coronary artery disease (CAD) is the leading cause of death in patients with type 2 diabetes mellitus (T2DM) and may be asymptomatic. Objective: The objective of this study was to assess the prevalence of asymptomatic myocardial ischemia in ...

MRI of Myocardial Perfusion

Seminars in Ultrasound, CT and MRI, 2006
An overwhelming number of myocardial perfusion studies are done by nuclear isotope imaging. Magnetic resonance imaging during the first pass of an injected, contrast bolus has some significant advantages for detection of blood flow deficits, namely higher spatial resolution, absence of ionizing radiation, and speed of the test.
