statistical analysis
| high-kV technique | Chest radiography using a kilovoltage of at least 125 kVp, usually 140-150 kVp, to reduce patient dose and increase latitude. (05 Mar 2000) |
|---|---|
| sealed jar technique | A technique for producing suspended animation in small experimental animals, consisting of sealing the animal in a jar which is then refrigerated. (05 Mar 2000) |
| Seldinger technique | A method of percutaneous insertion of a catheter into a blood vessel or space, such as an abscess cavity: a needle is used to puncture the structure and a guide wire is threaded through the needle; when the needle is withdrawn, a catheter is threaded over the wire; the wire is then withdrawn, leaving the catheter in place.

| hysterosalpingogram: kidde technique | <radiology> Instruments, single-toothed tenaculum: maintain seal and provide traction, acorn tip, Kidde cannula contrast, Sinografin (meglumine diatrizoate/iodipamide), Renografin (meglumine iothol diatrizoate) both water soluble, advantages: quicker filling, better visualization, absorbed rapidly from peritoneum, no vasc embol of particulates, no local inflamm treatmentn, disadvantage: increased pain with rapid distention technical problems, contrast instilled too quickly hides subtle abnormality: small polyp, small leiomyoma, synechiae, leak around os due to patulous or stenotic cervix, bicornuate or septate uterus (use shorter tip), lack of tubal filling: non-specific finding, may be technique, cornual spasm, mucous plug, reinject with Glucagon 1mg positive findings, peritoneal spillage if rugal fold of ampulla seen, contrast may loculate in peri-fimbrial adhesion (12 Dec 1998) |
| sterile insect technique | A technique used to control or eradicate insect pests or vectors, utilizing induction by irradiation of dominant lethality in the chromosomes of the released insects. (05 Mar 2000) |
| subtraction technique | Combination or superimposition of two images for demonstrating differences between them (e.g., radiograph with contrast vs. One without, radionuclide images using different radionuclides, radiograph vs. Radionuclide image) and in the preparation of audiovisual materials (e.g., offsetting identical images, colouring of vessels in angiograms). (12 Dec 1998) |
| delphi technique | An iterative questionnaire designed to measure consensus among individual responses. In the classic delphi approach, there is no interaction between responder and interviewer. (12 Dec 1998) |
| dental casting technique | <dentistry> The process of producing a form or impression made of metal or plaster using a mold. (12 Dec 1998) |
| dental impression technique | Procedure of producing an imprint or negative likeness of the teeth and/or edentulous areas. Impressions are made in plastic material which becomes hardened or set while in contact with the tissue. They are later filled with plaster of paris or artificial stone to produce a facsimile of the oral structures present. Impressions may be made of a full complement of teeth, of areas where some teeth have been removed, or in a mouth from which all teeth have been extracted. (12 Dec 1998) |
| direct technique | In dentistry, an inlay technique in which the wax pattern is made directly in the prepared cavity in the tooth. Synonym: direct technique. (05 Mar 2000) |
| dye dilution technique | Method for assessing flow through a system by injection of a known quantity of dye into the system and monitoring its concentration over time at a specific point in the system. (12 Dec 1998) |
| ilizarov technique | A bone fixation technique using an external fixator (fixators, external) for lengthening limbs, correcting pseudarthroses and other deformities, and assisting the healing of otherwise hopeless traumatic or pathological fractures and infections, such as chronic osteomyelitis. The method was devised by the russian orthopedic surgeon gavriil abramovich ilizarov (1921-1992). (12 Dec 1998) |
| immunoperoxidase technique | An immunologic test that utilises antibodies chemically conjugated to the enzyme peroxidase. (05 Mar 2000) |
| indirect technique | indirect method for making inlays |
| Ouchterlony technique | A technique in which both reaction partners (antigen and antibody) are allowed to diffuse to each other in a gel in a precipitation reaction. (05 Mar 2000) |
