Synonym: digital reflex, Hoffmann's reflex, snapping reflex. (05 Mar 2000) |
| digital subtraction angiography | Computer-assisted roentgenographic angiography permitting visualization of vascular structures without superimposed bone and soft tissue density; images made before and after contrast injection allow subtraction (separation and removal) of opacities not enhanced by the contrast medium. Other image-processing can be performed. Contrast material may be injected intravenously or in lower-than-usual amount intra-arterially. (05 Mar 2000) |

Synonym: vaginae fibrosae digitorum pedis. (05 Mar 2000) |
| fibrous digital sheaths of hand | Fibrous sheaths of the digits of the hand, the tubular fibrous layers that enclose the synovial sheaths and the superficial and deep flexor tendons and the tendon of the flexor pollicis longus in their passage along their respective digits; they are composed of annular and cruciform parts.
