|---|---|---|---|
| 설명 | 전자자기방사선을 방출하여 핵을 붕괴시키는 현상으로 원소기호 83번 이상인 모든 원소의 자연적 특성이며, 또한 다른 모든 원소들도 방사능을 가지도록 유도하는 것이 가능하다. 이런 성질을 이용하여, 여러 가지 치료 및 진단에 쓰인다. |

| 영문 | radioimmunoassay(=RIA) | 한글 | 방사면역측정법 |
|---|---|---|---|
| 설명 | 항원 혹은 항체의 존재여부와 양을 알아보는 아주 민감한 방법으로, 항원을 정량할 때는 항체와 방사성물질로 표시된 항원을 표본에 넣은 후 항원만 존재하는 분획과 항원과 항체가 결합되어 있는 분획을 분리해 내어, 각각의 방사능을 측정하여 표본의 항원량을 알아낸다. 즉, 표본항원의 양은 항원만 존재하는 분획의 방사능과는 비례관계에 있고, 항원-항체 분획과는 반비례관계에 있으므로 이들의 관계로 표본의 항원의 양을 계산해 낼 수 있다. 이런 방법은 여러 가지 면에서 장점도 있으나 방사능에 폭로된다는 단점이 있어 요즘은 효소면역측정법을 많이 사용한다. |

|---|---|---|---|
| 설명 | 원소기호는 같으나 중성자수가 다른 것을 동위원소라 하며, 방사능을 가지는 동위원소를 방사성 동위원소라고 한다. 이들은 안정된 동위원소로 핵반응기, 사이클로트론을 사용하여 만들어 낼 수 있는데, 이들은 핵의학 스캔, 방사 면역측정, 암의 치료에 이용된다. 이것은 3가지의 방사선입자를 분비하는데 알파입자, 베타입자, 감마입자가 그것이다. 이중 감마입자는 투과성이 뛰어나 진단과 치료에 많이 이용된다. |

| 영문 | radiology | 한글 | 방사선과학 |
|---|---|---|---|
| 설명 | 방사선의학. 의료에 사용할 수 있는 각종 방사선을 이용하여 질병의 진단 및 치료와 그 질병의 병태생리 또는 생화학적 연구를 하는 학문. 이는 X선을 이용하는 분야와 방사성 동위원소를 이용하는 핵의학 분야로 분류된다. X선을 이용한 질병의 진단은 X선이 신체 내의 조직 또는 이물 등에 의해 흡수 또는 산란되는 차에 의한 X선의 강도변화를 필름 또는 형광물질에 투영시켜 그 투과양상에 따라 판정하는 것으로, 특수검사시는 조영제-형광판-TV-컴퓨터 또는 정전기 등을 이용하여 진단율을 높인다. |

| radial aplasia-thrombocytopenia syndrome | <syndrome> Aplasia (absence) of the radius (the long bone on the thumb-side of the forearm) and thrombocytopenia (low blood platelets) are key features characterizing this syndrome. There is phocomelia (flipper-limb) with the thumbs always present. The fibula (the smaller bone in the lower leg) is often absent. The risk of bleeding from too few platelets is high in early infancy but lessens with age. The condition is inherited in an autosomal recessive trait with one gene (on a non-sex chromosome) coming from each parent to the child affected with the disease. Alternative names include thrombocytopenia-absent radius syndrome, tar syndrome, and tetraphocomelia-thrombocytopenia syndrome. (12 Dec 1998) |
|---|---|
| radial artery | <anatomy, artery> The direct continuation of the brachial trunk, originating at the bifurcation of the brachial artery opposite the neck of the radius. Its branches may be divided into three groups corresponding to the three regions in which the vessel is situated, the forearm, wrist, and hand. (12 Dec 1998) |
| radial border of forearm | An imaginary line running along the outermost extent of the forearm separating anterior and posterior surfaces laterally. Synonym: margo lateralis antebrachii, margo radialis antebrachii, radial border of forearm. (05 Mar 2000) |
| radial bursa | <anatomy> The synovial sheath that envelops the tendon of the flexor pollicis longus in its course through the carpal canal; it is continuous with the digital sheath of the thumb, the two generally being considered as one sheath. Synonym: vagina tendinis musculi flexoris pollicis longi, radial bursa. (05 Mar 2000) |
| radial clubhand | Clubhand with angular deviation towards radial side of limb. See: manus valga. (05 Mar 2000) |
| radial collateral artery | <anatomy, artery> The anterior terminal branch of the profunda brachii, anastomosing with the radial recurrent, forming part of the articular network of the elbow. Synonym: arteria collateralis radialis. (05 Mar 2000) |
| radial collateral ligament | The ligament that connects the lateral epicondyle of the humerus with the annular ligament of the radius. Synonym: ligamentum collaterale radiale, lateral ligament of elbow, radial collateral ligament. (05 Mar 2000) |
| radial collateral ligament of elbow | The ligament that connects the lateral epicondyle of the humerus with the annular ligament of the radius. Synonym: ligamentum collaterale radiale, lateral ligament of elbow, radial collateral ligament. (05 Mar 2000) |
| radial collateral ligament of wrist | The ligament that extends distally from the styloid process of the radius to the carpal bones. Synonym: ligamentum collaterale carpi radiale, external collateral ligament of wrist, lateral ligament of wrist. (05 Mar 2000) |
| radial eminence of wrist | A rather large flat eminence on the radial side of the palmar aspect of the wrist, due to the tuberosity of scaphoid and the ridge on the trapezium. Synonym: eminentia carpi radialis. (05 Mar 2000) |
| radial flexor muscle of wrist | <anatomy, muscle> Origin, common flexor origin of the medial condyle of humerus; insertion, anterior surface of the base of the second and most often sending a slip to that of the third metacarpal bone; action, flexes and abducts wrist radialward; nerve supply, median; its tendon travels in its own canal roofed by a layer of the transverse carpal ligament. Synonym: musculus flexor carpi radialis, radial flexor muscle of wrist. (05 Mar 2000) |
| radial fossa of humerus | A shallow depression on the anterior aspect of the distal humerus, superior to the capitulum of the humerus and lateral to the coronoid fossa, in which the margin of the head of the radius rests when the elbow is in extreme flexion. Synonym: fossa radialis humeri. (05 Mar 2000) |
| radial growth phase | The early pattern of growth of cutaneous malignant melanoma, in which tumour cells spread laterally in the epidermis. (05 Mar 2000) |
| radial head | The name applied to a head of origin of a muscle arising from the radius. Nomina Anatomica no longer lists any muscles as having radial heads, although formerly a radial head was listed for the flexor digitorum superficialis muscle Synonym: caput radiale. (05 Mar 2000) |
| radial head subluxation | Subluxation of the radial head within the elbow joint is also referred to as nursemaid's elbow. This orthopaedic condition is seen commonly in toddlers who may be lifted up by outstretched arms. Instability of the radial head leads to subluxation. The child with nursemaid's usually has their arm in hanging in extension at their side and any attempted movement of the elbow joint is met with pain. (27 Sep 1997) |
