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.
Technetium (99m Tc) sestamibi (commonly sestamibi; USP: technetium Tc 99m sestamibi; trade name Cardiolite) is a pharmaceutical agent used in nuclear medicine imaging. The drug is a coordination complex consisting of the radioisotope technetium-99m bound to six (sesta=6) methoxyisobutylisonitrile (MIBI) ligands. The anion is not defined.
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.
From about 2004 to 2011, [4] [5] U.S. military planners used various "Tier systems" to designate the various elements in an overall plan for integrated operations. [6] The Tiers do not refer to specific models of aircraft, but rather roles the aircraft would fill.
The Northrop Grumman XRQ-73 SHEPARD (Series Hybrid Electric Propulsion AiRcraft Demonstration) is an hybrid-electric Group 3 unmanned aerial vehicle (weighting about 1,250 lb (570 kg)) developed by Northrop Grumman.
Radionuclide angiography is an area of nuclear medicine which specialises in imaging to show the functionality of the right and left ventricles of the heart, thus allowing informed diagnostic intervention in heart failure.
