| RNV | Radionuclide venography |
| venography | <investigation> A special X-ray of the veins that is performed by first injecting a radiopaque contrast (shows up on X-ray) into the vein in question and then taking a conventional X-ray. Used to demonstrate a blockage of a vein. Commonly used in the lower extremities to diagnose deep venous thrombosis. (27 Sep 1997) |

| vertebral venography | Radiographic demonstration of the epidural venous plexus by injection of contrast medium into the spinous process. (05 Mar 2000) |
| splenic portal venography | Introduction of radiopaque material into the spleen to obtain an X-ray visualization of the portal vessel of the portal circulation. Synonym: splenic portal venography. Origin: spleno-+ portography (05 Mar 2000) |
| infusions, intraosseous | The adminstration of medication or fluid through a needle directly into the bone marrow. The technique is especially useful in the management of paediatric emergencies when intravenous access to the systemic circulation is difficult. (12 Dec 1998) |
| intraosseous | Within bone. Synonym: intraosteal. Origin: intra-+ L. Os, bone (05 Mar 2000) |
| intraosseous anaesthesia | Rarely used method of general anaesthesia by injection of intravenous anaesthetic agent(s) into the medullary canal of long bones. Synonym: intraosseous anaesthesia. (05 Mar 2000) |
| intraosseous fixation | The use of internal metal plates, screws or rods to stabilise bone fragments. A procedure used to correct serious orthopaedic bone fractures that cannot be stabilised by casting or splinting. See: external fixation. (27 Sep 1997) |
| transosseous venography | Radiographic demonstration of veins that drain a bone's marrow, by injection of contrast medium into the marrow at an appropriate point, as in vertebral venography or azygography by rib injection. (05 Mar 2000) |
| intraosseous venography |
radiography of the veins after injection of the contrast medium into bone marrow at an appropriate site, such as the iliac crest, ischium, pubic bones, greater trochanter, spinous processes of the vertebrae, or sternum.
