| 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. |

| 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 | 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 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) |
| 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) |
| radionuclide imaging | Process whereby a radionuclide is injected or measured (through tissue) from an external source, and a display is obtained from any one of several rectilinear scanner or gamma camera systems. The image obtained from a moving detector is called a scan, while the image obtained from a stationary camera device is called a scintiphotograph. (12 Dec 1998) |
| radionuclide scan | An exam that produces pictures (scans) of internal parts of the body. The patient is given an injection or swallows a small amount of radioactive material. A machine called a scanner then measures the radioactivity in certain organs. (12 Dec 1998) |
| radionuclide ventriculography | Imaging of a ventricle of the heart after the injection of a radioactive contrast medium. The technique is less invasive than cardiac catheterization and is used to assess ventricular function. (12 Dec 1998) |
| gated radionuclide angiocardiography | Radionuclide angiocardiography using cardiac gating to combine images from several cardiac cycles to improve the quality of the images of separate phases (e.g., systole and diastole). (05 Mar 2000) |
| exercise radionuclide angiocardiography | Radionuclide angiocardiography while performing exercise, such as on a treadmill or bicycle. (05 Mar 2000) |
| 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) |
