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.
Abnormalities in cardiac function may be manifested as a decrease in LVEF and/or the presence of abnormalities in global and regional wall motion. For normal subjects, peak filling rates should be between 2.4 and 3.6 end diastolic volume (EDV) per second, and the time to peak filling rate should be 135-212 ms. [citation needed]
Through Dec. 9, the western half of the U.S. is forecast to have above normal or near normal temperatures, the agency says. The extended U.S. temperature forecast for Dec. 5-9.
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.

In semiconductor manufacturing, the 2 nm process is the next MOSFET (metal–oxide–semiconductor field-effect transistor) die shrink after the 3 nm process node.. The term "2 nanometer", or alternatively "20 angstrom" (a term used by Intel), has no relation to any actual physical feature (such as gate length, metal pitch or gate pitch) of the transistors.
