| radionuclide angiocardiography | The display, by means of a stationary scintillation camera device, of the passage of a bolus of a rapidly injected radiopharmaceutical. Synonym: radionuclide ventriculography. (05 Mar 2000) |
| exercise radionuclide angiocardiography | Radionuclide angiocardiography while performing exercise, such as on a treadmill or bicycle. (05 Mar 2000) |
| angiocardiography | Radiography of the heart and great vessels after injection of a contrast medium. (12 Dec 1998) |
| gated blood pool imaging | Radionuclide ventriculography where scintigraphic data is acquired during repeated cardiac cycles at specific times in the cycle, using an electrocardiographic synchroniser or gating device. Analysis of right ventricular function is difficult with this technique; that is best evaluated by first-pass ventriculography (ventriculography, first-pass). (12 Dec 1998) |
| gated ion channel | <physiology> Transmembrane proteins of excitable cells, that allow a flux of ions to pass only under defined circumstances. Channels may be either voltage gated, such as the sodium channel of neurons or ligand gated such as the acetylcholine receptor of cholinergic synapses. Channels tend to be relatively ion specific and allow fluxes of typically 1000 ions to pass in around 1ms, they are thus much faster at moving ions across a membrane than transport ATPases. (05 May 1997) |
| voltage-gated channel | A class of ion channel's that open and close in response to change in the electrical potential across the plasma membrane of the cell; voltage-gated Na+ c.'s are important for conducting action potential along nerve cell processes. (05 Mar 2000) |
| voltage gated ion channel | <physiology> A transmembrane ion channel whose permeability to ions is extremely sensitive to the transmembrane potential difference. These channels are essential for neuronal signal transmission and for intracellular signal transduction. See: sodium channel. (18 Nov 1997) |
| ligand-gated channel | A class of ion channel's whose ionic permeability is regulated by cell membrane receptors that respond to specific extracellular chemical signals. (05 Mar 2000) |
| ligand gated ion channel | A transmembrane ion channel whose permeability is increased by the binding of a specific ligand, typically a neurotransmitter at a chemical synapse. The permeability change is often drastic, such channels let through effectively no ions when shut, but allow passage at up to 10exp7 ions sexp 1 when a ligand is bound. Recently, the receptors for both acetylcholine and GABA have been found to share considerable sequence homology, implying that there may be a family of structurally related ligand gated ion channels. (18 Nov 1997) |
| radionuclide | An isotope of artificial or natural origin that exhibits radioactivity.Radionuclides serve as agents in nuclear medicine and genetic engineering, play a role in computer imaging for diagnosis and experiment, and account for a percentage of background radiation to which humans are exposed. In cancer therapy, radionuclides that localise to certain organs (e.g., radioactive iodine or gallium), deliver cytotoxic radiation doses to tumours. Similarly, radionuclides can be yoked to monoclonal antibodies engineered to attack specific populations of cancerous cells. In positron emission tomography, glucose molecules tagged with radionuclides are injected into the bloodstream. The gamma radiation emitted by the decay of the radionuclides reveals areas of active glucose uptake and thus offers a gauge of cell metabolism and function. (05 Mar 2000) |
| radionuclide angiography | The measurement of visualization by radiation of any organ after a radionuclide has been injected into its blood supply. It is used to diagnose heart, liver, lung, and other diseases and to measure the function of those organs, except renography, for which radioisotope renography is available. (12 Dec 1998) |
| radionuclide cisternography | Scintigraphic imaging of the cisterns at the base of the brain following subarachnoid injection of a gamma-emitting radiopharmaceutical. (05 Mar 2000) |
| radionuclide generator | A column containing a large amount of a particular radionuclide (mother radionuclide) that decays down to a second radionuclide of shorter physical half-life; the daughter radionuclide is separated from the parent by the process of elution and affords a continuing supply of relatively short-lived radionuclides for laboratory use; the elution is loosely termed "milking" with the generator referred to as a "radioactive cow." (05 Mar 2000) |
| radionuclide generators | Separation systems containing a relatively long-lived parent radionuclide which produces a short-lived daughter in its decay scheme. The daughter can be periodically extracted (milked) by means of an appropriate eluting agent. (12 Dec 1998) |
