| ADSA | Arterial Digital Subtraction Angiography |
| DSA | Digital Subtraction Angiography = DVI |
| superficial palmar venous arch | The venous arch accompanying the superficial palmar arterial arch it consists usually of paired venae comitantes and is drained by the superficial ulnar and radial veins. Synonym: arcus venosus palmaris superficialis. (05 Mar 2000) |
|---|---|
| deep palmar (arterial) arch | The arterial arch located deep to the long flexor tendons in the hand. It is formed by the terminal part of the radial artery in conjunction with the deep palmar branch of the ulnar artery. The arch gives rise to palmar metacarpal and princeps pollicis arteries. Synonym: arcus palmaris profundus, arcus volaris profundus. (05 Mar 2000) |
| deep palmar branch of ulnar artery | <anatomy, artery> Branch of the ulnar artery which supplies the hypothenar muscles then passes deep into the palm to the flexor tendons and anastomoses with the deep palmar arch from the radial artery. Synonym: ramus palmaris profundus arteriae ulnaris. (05 Mar 2000) |
| deep palmar venous arch | The venous arch that accompanies the deep palmar arterial arch it usually consists of paired venae comitantes. Synonym: arcus venosus palmaris profundus. (05 Mar 2000) |
| lateral central palmar space | The more lateral (radial) of the central palmar spaces, bounded laterally by the thenar compartment; related distally to the synovial tendon sheath of the index finger and proximally to the common flexor sheath. Synonym: lateral midpalmar space. (05 Mar 2000) |
| long palmar muscle | <anatomy, muscle> Origin, medial epicondyle of humerus; insertion, flexor retinaculum of wrist and palmar fascia; action, makes palmar fascia tense and flexes the hand and forearm; is absent about 20% of the time; when tensed, its tendon stands out sharply at the wrist and overlies the median nerve; nerve supply, median. Synonym: musculus palmaris longus, long palmar muscle. (05 Mar 2000) |
| analog-digital conversion | The process of converting analog data such as continually measured voltage to discrete, digital form. (12 Dec 1998) |
| 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) |
| annular part of fibrous digital sheath | One of the two circular fibrous bands of the fibrous sheaths of the fingers and toes attached to the shaft of the proximal and middle phalanges. Synonym: pars annularis vaginae fibrosae, annular pulley, annulus of fibrous sheath, ligamentum annulare digitorum. (05 Mar 2000) |
| radiography, dental, digital | A rapid, low-dose, digital imaging system using a small intraoral sensor instead of radiographic film, an intensifying screen, and a charge-coupled device. It presents the possibility of reduced patient exposure and minimal distortion, although resolution and latitude are inferior to standard dental radiography. A receiver is placed in the mouth, routing signals to a computer which images the signals on a screen or in print. It includes digitizing from X-ray film or any other detector. (12 Dec 1998) |
| recurring digital fibromas of childhood | Multiple fibrous flesh-coloured nodules on the extensor aspect of the terminal phalanges of adjacent digits of infants and young children which often recur after attempted excision, do not metastasize, and may spontaneously regress in two to three years; composed of spindle cells containing cytoplasmic inclusions believed to be derived from myofibrils. Synonym: infantile digital fibromatosis. (05 Mar 2000) |
| collateral digital artery | <anatomy, artery> Terminal branches of the common palmar digital artery that pass to the side of each finger. Synonym: arteria digitalis palmaris propria, collateral digital artery, digital collateral artery. (05 Mar 2000) |
| common plantar digital artery | <anatomy, artery> One of four arteries arising from a superficial plantar arch, when present as a variation. They unite with the plantar metatarsal arteries. Synonym: arteria digitalis plantaris communis. (05 Mar 2000) |
| common plantar digital nerves | Three nerves derived from the medial plantar and one from the lateral plantar that supply the skin overlying the metatarsals and terminate as proper plantar digital nerves to the side of each toe. Synonym: nervi digitales plantares communes. (05 Mar 2000) |
| plantar digital veins | Drain the plantar and distal dorsal aspects (nail beds) of the toes and pass back to form four metatarsal veins that in turn empty into the plantar venous arch. Synonym: venae digitales plantares. (05 Mar 2000) |
