| 설명 | 인체의 장기나, 병적인 모양, 종양의 위치, 림프절의 비대 등에 대한 진단을 내리기 위해 시행하는 방사선학적인 검사방법이다. 현재 많이 쓰이고 있는 컴퓨터단층촬영술(CT: computerized tomography)과는 다른 방법으로 시행하며, 그 해상도가 컴퓨터단층촬영보다는 뛰어나 비록 고가이긴 하지만, 많이 쓰이고 있다. 또한 인체에 무해하고, 여러 가지 면에서 사람을 단층으로 분리시켜 볼 수 있는 등 장점이 많다. 단점은 심장박동기를 설치한 사람이나, 주위에 장을 띠는 물체를 몸에 지니고 있는 중환자 등에서는 이용할 수 없고, 복부장기에 대한 진단에는 컴퓨터단층촬영보다 불리한 것으로 되어 있으며, 무엇보다 설치비와 그 시술비가 비싸다는데 가장 큰 단점이 있다. |

| 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 | 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 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) |
| 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 imaging | <radiology> Cortex, I-131 iodo-cholesterol, not widely used due to high rad dose and 4-15 day delayed imaging, medulla, search for pheo, MIBG (I-131 meta-iodobenzylguanidine) (12 Dec 1998) |
| adrenal medullary imaging | <investigation, radiology> A nuclear scan that images the adrenal glands after a radioactive tracer is injected into the bloodstream. This test is useful in detecting a pheochromocytoma, particularly if it not within the adrenal gland. (27 Sep 1997) |
| backscattered electron imaging | <microscopy> The production of backscattered electrons from a sample varies directly with the specimen's average atomic number, higher atomic number elements produce more backscattered electrons than lower atomic number ones. Detection of Backscattered Electrons is achieved by using a donut shaped solid state saemiconductor device mounted on the bottom of the objective lens. When Backscattered Electrons strike the detector electron-hole pairs are created which are then counted. This quantity is translated into a pixel intensity and displayed on the CRT, forming the image. By splitting the detector into halves (or quadrants) differences in the signal level on the individual detector segments provide surface topography information. (05 Aug 1998) |
| blood pool imaging | Nuclear medicine study using a radionuclide that is confined to the vascular compartment. (05 Mar 2000) |
| bone: gallium imaging | <radiology> Increased activity in: active osteomyelitis (90% sensitivity: better than Tc-99m MDP), sarcoma, cellulitis, septic arthritis, rheumatoid arthritis, Paget disease, metastases (65% sensitivity: than for bone agents) see: gallium: indications (12 Dec 1998) |
