| 영문 | positron emission tomography | 한글 | 양전자방출 단층촬영 |
|---|---|---|---|
| 설명 | 핵의학적 진단방법중 하나. 가장 발달된 형태의 핵의학적 진단방법이다. 양전자를 방출함으로써 생기는 핵의학적 방사능을 이용하여 인체의 단면을 촬영할 수 있다. 이것은 마치 컴퓨터단층촬영과 유사하나, 조영제와 X-선을 사용하지 않는다는 점에서 다르다. 이용하는 핵의학적 물질을 인체내에서 대사가능한 물질(예를 들어 포도당, 혹은 지방)에 붙여서 사용함으로써, 실제적으로 살아있는 생체내에서 어떤 형태로 대사가 이루어지는 지 알아낼 수도 있다. 예를 들면, 눈을 뜨고 어떤 물체를 주시할 때, 뇌의 어떤 부위가 가장 활발한 대사작용을 하는지 알 수 있다. |

|---|---|---|---|
| 설명 | 피부를 날카로운 바늘로 긁어 피부의 반응을 보는 검사로 피부 과민반응이나 알레르기를 알아보기 위한 검사이다. 바늘끝에 항원을 묻힌 뒤, 피부밑을 긁어 반응을 알아본다. 이때 항원이 아닌 대조물질(예를 들어 보통의 물)을 묻힌 바늘을 같이 반응하여 피부묘기증(dermographism) 단지 바늘의 긁힘만으로 알레르기 같은 반응을 일으키는 현상과 감별해야 한다. 난청, 청력소실(hearing loss) 청각이 저하 또는 상실된 상태. 원인과 정도는 여러 가지인데, 난청은 그 정도가 가장 심한 상태이다. 청각의 전도경로에 장애가 있을 때 난청이 일어나고, 그 병터가 외이도나 중이에 있는 것을 전음난청, 내이에 있는 것을 감음 난청이라 하여 구분한다. 또 병터의 자리를 명시하여 중이성 난청이나 미로성 난청 등으로 세분하기도 한다. |

| otoacoustic | Referring to the very faint sounds produced by the ear; thought to represent mechanical vibrations in the cochlea. (05 Mar 2000) |
|---|---|
| otoacoustic emissions, spontaneous | Sinusoidal tones originating in the cochlea. These faint sounds, with levels between 10-30 decibels, are usually not recognised by the persons having them. However, the emissions can be recorded using sensitive microphones placed in the ear canals. The clinical significance of having or not having spontaneous otoacoustic emissions is unclear; however, some association between tinnitus and the spontaneous emissions has been reported. (12 Dec 1998) |
| alpha emission | <physics> Form of nuclear decay where the nucleus emits an alpha particle (see entry below). (09 Oct 1997) |
| beta emission | <radiobiology> Form of nuclear decay where a neutron splits into a proton plus electron plus neutrino set. The proton stays in the nucleus but the electron (beta ray) is ejected. (09 Oct 1997) |
| gamma emission | <physics> Nuclear decay process whereby the nucleus goes from an excited state to a more stable state by emitting a gamma ray. See: gamma ray. (09 Oct 1997) |
| particulate emission | Fine liquid or solid particles discharged with exhaust gases. Usually measured as grains per cubic foot or pounds per million Btu input. (05 Dec 1998) |
| characteristic emission | Monochromatic radiation that is produced when an electron is ejected from an atom and another takes its place by jumping from another shell; the energy of the photon is the difference between that of the two shell positions. Synonym: characteristic emission. (05 Mar 2000) |
| microscope, field emission | <microscopy> An image-forming device in which a strong electrostatic field causes cold emission of electrons from a sharply rounded point or from a specimen that has been placed on that point. The electrons are accelerated to a phosphorescent screen, or photographic film, giving a visible picture of the variation of emission over the specimen surface. (05 Aug 1998) |
| positron emission tomography | <radiology> A highly specialised research imaging technique using short lived radioactive substances - usually those made with a cyclotron. This technique is very sensitive in picking up active tumour tissue but does not measure the size of it. Tomographic images are formed by computer analysis of photons detected from annihilation of positrons emitted by radionuclides incorporated into biochemical substances; the images, often quantitated with a colour scale, show the uptake and distribution of the substances in the tissue, permitting analysis and localization of metabolic and physiological function. Because the half-lives of the radionuclides are so short (20 minutes to 2 hours), and the equipment expensive, PET is rarely used in a clinical setting. But since its development in the mid-1970s, it has proved the most important tool yet devised for experimental investigation of the living brain, whether healthy, traumatised, or diseased. With CT and MRI, it represents a new generation of computer imaging techniques that have revolutionised medicine and physiology. Acronym: PET (20 Jun 2000) |
| single photon emission computed tomography | <radiology> Tomographic imaging of metabolic and physiological functions in tissues, the image being formed by computer synthesis of photons of a single energy emitted by radionuclides administered in suitable form to the patient. The method uses radionuclides which emit a single photon of a given energy. The camera is then rotated 180 or 360 degrees around the patient to capture images at multiple positions along the arc. The computer then reconstructs the transaxial, sagittal, and coronal images from the 3-dimensional distribution of radionuclides in the target area scanned. The advantages of SPECT are that it can be used to observe biochemical and physiological processes as well as the size and volume of the organ. The disadvantage is that, unlike positron emission tomography where the positron-electron annihilation results in the emission of 2 photons at 180 degrees from each other, SPECT requires physical collimation to line up the photons, which results in the loss of available photons and hence degrades the image. Acronym: SPECT (20 Jun 2000) |
| source emission reduction plan | (SERP) A contingency plan developed to reduce emissions during an air quality emergency. (05 Dec 1998) |
| spectrometry, X-ray emission | Identification and measurement of concentration of elements based on the fact that X-rays emitted by an excited element have a wavelength characteristic of that element and an intensity related to its concentration. It includes fluorescence, or secondary-emission, X-ray spectrometry, in which the specimen is irradiated by X-rays. Primary-emission x-ray spectrometry, in which the specimen is bombarded by electrons, is a specific type of X-ray emission spectrometry known as electron probe microanalysis. (12 Dec 1998) |
| spontaneous emission | <radiobiology> Radiation randomly emitted by excited atoms or ions. Contrast with stimulated emission. (09 Oct 1997) |
| stimulated emission | <radiobiology> Radiation coherently emitted by excited ions when driven by a passing light wave and the appropriate transition wavelength. Laser means Light Amplification by Stimulated Emission of Radiation, it occurs when there is a population inversion between the upper and lower energy states of the transition, such that stimulated emission can dominate excitation. Stimulated emission is coherent and codirectional with the stimulating wave, and the rate of stimulated emission is proportional to the intensity of the stimulating wave. (09 Oct 1997) |
| ion cyclotron emission | <radiobiology> As ions gyrate around in a magnetic field (see also larmor radius or cyclotron radius), they radiate radio-frequency electromagnetic waves. This is known as ion cyclotron emission, and can be measured to help diagnose a plasma. (09 Oct 1997) |
