| 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. |

| 설명 | 다른 말로 MRI=Magnetic Resonance Imaging 자기공명영상이라고도 한다. 인체의 장기나, 병적인 모양, 종양의 위치, 림프절의 비대 등에 대한 진단을 내리기 위해 시행하는 방사선학적인 검사방법이다. 현재 많이 쓰이고 있는 컴퓨터단층촬영(CT=computerized tomography)과는 다른 방법으로 시행하며, 그 해상도가 컴퓨터단층촬영보다는 뛰어나 비록 고가이긴 하지만, 많이 쓰이고 있다. 또한 인체에 무해하고, 여러 가지 면(plane)에서 사람을 단층시켜 볼 수 있다. 단점은 심장박동기를 설치한 사람이나, 주위에 자장을 띠는 물체를 몸에 지니고 있는 중환자 등에서는 이용할 수 없고, 복부장기에 대한 진단에는 컴퓨터단층촬영보다 떨어지는 것으로 되어 있다. |

| 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. |

| 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) |

| Magnetic Resonance Imaging | A special imaging technique used to image internal stuctures of the body, particularly the soft tissues. An MRI image is often superior to a normal X-ray image. It uses the influence of a large magnet to polarize hydrogen atoms in the tissues and then monitors the summation of the spinning energies within living cells. Images are very clear and are particularly good for soft tissue, brain and spinal cord, joints and abdomen. These scans may be used for detecting some cancers or for following their progress. Acronym: MRI (11 Nov 1997) |

| magnetic resonance imaging, cine | A type of imaging technique used primarily in the field of cardiology. By coordinating the fast gradient-echo mri sequence with retrospective ecg-gating, numerous short time frames evenly spaced in the cardiac cycle are produced. These images are laced together in a cinematic display so that wall motion of the ventricles, valve motion, and blood flow patterns in the heart and great vessels can be visualised. (12 Dec 1998) |

| nuclear magnetic resonance | Spectroscopic method of measuring the magnetic moment of atomic nuclei in a covalent bond. Clinical application is in biochemical, metabolic, and physiologic studies of living tissue. It includes proton and electron spin-echo and spin-relaxation times. (12 Dec 1998) |
| nuclear magnetic resonance, biomolecular | Nmr spectroscopy on small- to medium-size biological macromolecules. This is often used for structural investigation of proteins and nucleic acids, and often involves more than one isotope. (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) |
| magnification angiography | Enhanced imaging of small blood vessels using an increased distance from subject to film, as in magnification radiography. (05 Mar 2000) |
