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.
Gated SPECT is a nuclear medicine imaging technique, typically for the heart in myocardial perfusion imagery. [1] An electrocardiogram (ECG) guides the image acquisition, and the resulting set of single-photon emission computed tomography (SPECT) images shows the heart as it contracts over the interval from one R wave to the next.
Myocardial perfusion imaging (MPI) is a form of functional cardiac imaging, used for the diagnosis of ischemic heart disease. The underlying principle is that under conditions of stress, diseased myocardium receives less blood flow than normal myocardium. MPI is one of several types of cardiac stress test.
Single-photon emission computed tomography (SPECT), which creates 3-dimensional images of the target organ or organ system. Scintigraphy, creating 2-dimensional images. Uses of NM perfusion scanning include Ventilation/perfusion scans of lungs, myocardial perfusion imaging of the heart, and functional brain imaging.
SPECT provides information about blood flow to the heart and how well the heart is functioning. It is commonly used to evaluate patients who have, or are suspected to have, coronary artery disease and is additionally used for myocardial perfusion imaging. [23]
Technetium (99m Tc) sestamibi is a lipophilic cation which, when injected intravenously into a patient, distributes in the myocardium proportionally to the myocardial blood flow. Single photon emission computed tomography ( SPECT ) imaging of the heart is performed using a gamma camera to detect the gamma rays emitted by the technetium-99m as ...

82 Rb is widely used in myocardial perfusion imaging. This isotope undergoes rapid uptake by myocardiocytes, which makes it a valuable tool for identifying myocardial ischemia in Positron Emission Tomography (PET) imaging. 82 Rb is used in the pharmaceutical industry and is marketed as Rubidium-82 chloride under the trade names RUBY-FILL and ...
