| 설명 | 원래 혈관은 단순 X선 촬영에선 보이지 않는다. 그러나 혈관속에 X선 촬영시에 보이는 물질을 넣고 X선 촬영을 하면 혈관의 모양을 X선 촬영으로 알아볼 수 있게 된다. 이런 방법을 혈관조영술이라고 하고, 혈관의 병터를 알아 보는데 사용한다. 디지털감산혈관조영술(digital substraction angiography)은 혈관조영술의 한 방법으로 우선 혈관조영을 할 부분의 단순촬영을 실시하고 다음에 혈관 조영을 한다. 그렇게 하여 두 가지 촬영의 정보를 컴퓨터에 입력시켜 두번째 촬영의 정보에서 첫번째 촬영의 정보를 빼 도록한다. 그러면 혈관만 깨끗이 조영되고 나머지 부분의 영상이 없어진 것이 나오게 된다. 이렇게 하여 혈관부분의 영상을 더욱더 선명히 얻는 것을 디지털감산이라고 한다. 형광안저조영술(fluorescein angiography)은 주로 안과에서 눈의 혈관의 이상을 관찰할 때에 많이 사용하는 방법이다. 플로레신이란 형광을 띠는 물질로써 이것을 우선 혈관으로 주사한 뒤에 눈동자를 통해서 이 물질이 눈의 혈관을 통해 이동하는 것을 관찰함으로써 눈의 혈관의 상태를 알 수 있는 방법이다. |

| phase-amplitude contrast | <microscopy> The separation and recombination of direct vs. Diffracted rays in a light microscope adjusted to Kohler illumination. at the lower focal plane of the condenser there is an annular diaphragm with an opaque central stop. Through this diaphragm rays are focused as a hollow cone onto the specimen. In the back focal plane of the objective there is a conjugate annular diaphragm (phase plate). If here the undiffracted rays are retarded (by a transparent film of proper thickness on the annulus of the phase plate), bright contrast results. If, instead, the phase-delay film is on the central spot, dark contrast results. With either a bright or a dark-contrast phase plate, the annulus is usually coated with a partially absorbing (very thin) film of silver (Zernike method) or carbon soot (Wilska method) to reduce the higher amplitude (intensity) of the undiffracted rays.

| phase contrast | <microscopy> An optical method devised by F. Zernike for converting the focused image of a phase object (one with differences in refractive index or optical path but not in absorbance), which ordinarily is not visible in focus, into an image with good contrast. (05 Aug 1998) |
| phase-contrast microscope | <instrument> A specially constructed microscope that has a special condenser and objective containing a phase-shifting ring whereby small differences in index of refraction are made visible as intensity or contrast differences in the image; particularly useful for examining structural details in transparent specimens such as living or unstained cells and tissues. (05 Mar 2000) |
| phase contrast microscopy | <investigation> A simple nonquantitative form of interference micoscopy of great utility in visualising live cells. Small differences in optical path length due to differences in refractive index and thickness of structures are visualised as differences in light intensity. (18 Nov 1997) |
| microscopy, phase-contrast | A form of interference microscopy in which variations of the refracting index in the object are converted into variations of intensity in the image. This is achieved by the action of a phase plate. (12 Dec 1998) |
| adrenal angiography | <radiology> Adrenal arteriography, 3 arteries: superior - inferior phrenic a., middle - aorta, inferior - renal a., difficult to inject all 3; arteriography usually not attempted adrenal venography, venous sampling, may define anatomy, may rupture capsule and ablate function (12 Dec 1998) |
| angiography | <investigation> A radiographic technique where a radio-opaque (shows up on X-ray) contrast material is injected into a blood vessel for the purpose of identifying its anatomy on X-ray. This technique is used to image arteries in the brain, heart, kidneys, gastrointestinal tract, aorta, neck (carotids), chest, limbs and pulmonary circuit. (27 Sep 1997) |
| angiography catheter | A thin-walled tube suitable for percutaneous puncture and powered injection of contrast media for radiography; catheter diameter is measured on the French scale. (05 Mar 2000) |
| angiography, digital subtraction | A method of delineating blood vessels by subtracting a tissue background image from an image of tissue plus intravascular contrast material that attenuates the X-ray photons. The background image is determined from a digitised image taken a few moments before injection of the contrast material. The resulting angiogram is a high-contrast image of the vessel. This subtraction technique allows extraction of a high-intensity signal from the superimposed background information. The image is thus the result of the differential absorption of X-rays by different tissues. (12 Dec 1998) |
| biplane angiography | Synchronous angiocardiography in two planes at right angles to each other or in two orthogonal planes. (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) |
| magnetic resonance angiography | Non-invasive method of vascular imaging and determination of internal anatomy without injection of contrast media or radiation exposure. The technique is used especially in cerebral angiography as well as for studies of other vascular structures. (12 Dec 1998) |
| magnification angiography | Enhanced imaging of small blood vessels using an increased distance from subject to film, as in magnification radiography. (05 Mar 2000) |
| cerebral angiography | Radiography of the vascular system of the brain after injection of a contrast medium. (12 Dec 1998) |
| MR angiography | Imaging of blood vessels using special MR sequences which enhance the signal of flowing blood and suppress that from other tissues. Synonym: magnetic resonance angiography. (05 Mar 2000) |
