| 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. |

| magnetic viscosity | <physics> A magnetic field in a conducting fluid will damp fluid motions perpendicular to the field lines, similar to ordinary viscosity, even in the absence of sizeable mechanical forces or electric fields. (09 Oct 1997) |
|---|
| absolute viscosity | Force per unit area applied tangentially to a fluid, causing unit rate of displacement of parallel planes separated by a unit distance; units in CGS system: poise. (05 Mar 2000) |
|---|---|
| anomalous viscosity | The viscous behaviour of nonhomogenous fluids or suspensions, e.g., blood, in which the apparent viscosity increases as flow or shear rate decreases toward zero. (05 Mar 2000) |
| apparent viscosity | <physiology> This refers to the ratio of shear stress to shear rate in a fluid, this ratio is dependent on the rate of shear. (09 Oct 1997) |
| blood viscosity | The internal resistance of the blood to shear forces. The in vitro measure of whole blood viscosity is of limited clinical utility because it bears little relationship to the actual viscosity within the circulation, but an increase in the viscosity of circulating blood can contribute to morbidity in patients suffering from disorders such as sickle cell anaemia and polycythemia. (12 Dec 1998) |
| relative viscosity | The ratio of the viscosity of a solution or dispersion to the viscosity of the solvent or continuous phase. (05 Mar 2000) |
| viscosity | <chemistry> A physical property of fluids that determines the internal resistance to shear forces. (18 Nov 1997) |
| coefficient of viscosity | The value of the force per unit area required to maintain a unit relative velocity between two parallel planes a unit distance apart. (05 Mar 2000) |
| Poiseuille's viscosity coefficient | An expression of the viscosity as determined by the capillary tube method; the coefficient η = (πPr4t/8vl), where P is the pressure difference between the inlet and outlet of the tube, r the radius of the tube, l its length, and v the volume of liquid delivered in the time t. If volume is in cm3, time is in seconds, and l and r are in cm, then n will be in poise. (05 Mar 2000) |
| newtonian viscosity | The viscosity characteristics of a newtonian fluid. (05 Mar 2000) |
| dynamic viscosity | The internal or molecular frictional resistance of a fluid by Newton's law of viscosity as the ratio of the applied force per unit area to the relative velocity of adjacent fluid layers (produced by the force). (05 Mar 2000) |
| kinematic viscosity | A measure used in studies of fluid flow; the dynamic viscosity, u, in poises divided by the density of the material; units: stokes. (05 Mar 2000) |
| magnetic | 1. A magnet. "As the magnetic hardest iron draws." (Milton) 2. Any metal, as iron, nickel, cobalt, etc, which may receive, by any means, the properties of the loadstone, and which then, when suspended, fixes itself in the direction of a magnetic meridian. Source: Websters Dictionary (01 Mar 1998) |
| magnetic attraction | The force that draws iron or steel toward a magnet. (05 Mar 2000) |
| magnetic axis | <physics> This typically refers to the location of the innermost flux surface in a toroidal device, the one which encloses no volume and has therefore degenerated from a flux surface into a single field line. Roughly, the circle through the middle of the dough of the donut. Additionally, in systems with magnetic islands (see entry below), each island has a local magnetic axis, distinct from the overall magnetic axis of the torus. (09 Oct 1997) |
| magnetic confinement | <physics> Use of magnetic fields to confine a plasma. (Confinement involves restricting the volume of the plasma and/or restricting particle or energy transport from the centre of the plasma to the edge.) (09 Oct 1997) |
