| 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) |
| 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) |
| cruciform part of fibrous digital sheath | The fibres of the fibrous sheath of the fingers and toes which form X-shaped patterns over the region of the interphalangeal joints. Synonym: pars cruciformis vaginae fibrosae, crucial ligament, cruciform part of fibrous sheath, cruciform pulley, ligamenta cruciata digitorum. (05 Mar 2000) |
| proper plantar digital artery | <anatomy, artery> One of the digital branches of the plantar metatarsal arteries. Synonym: arteria digitalis plantaris propria. (05 Mar 2000) |
| proper plantar digital nerves | The ten nerves derived from the common plantar digital nerves; each nerve supplies a plantar quadrant of a toe and part of the dorsal surface of the distal phalanx. Synonym: nervi digitales plantares proprii. (05 Mar 2000) |
| digital | Relating to or resembling a digit or digits or an impression made by them; based on numerical methodology. (05 Mar 2000) |
| digital collateral 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) |
| digital crease | One of the grooves on the palmar surface of a finger, at the level of an interphalangeal joint. Synonym: digital flexion crease, digital furrow. (05 Mar 2000) |
| digital dilatation | Use of the finger or finger-tip to enlarge an orifice or opening, such as enlarging the orifice of a sclerosed mitral valve surgically. (05 Mar 2000) |
| digital flexion crease | One of the grooves on the palmar surface of a finger, at the level of an interphalangeal joint. Synonym: digital flexion crease, digital furrow. (05 Mar 2000) |
| digital fossa | A depression at the root of the neck of the femur beneath the curved tip of the great trochanter; it gives attachment to the tendon of the obturator externus. Synonym: fossa trochanterica, digital fossa. (05 Mar 2000) |
