| dilution | 1. The act of being diluted. 2. A diluted solution or mixture. 3. In microbiologic techniques, a method for counting the number of viable cells in a suspension; a sample is diluted to the point where an aliquot, when plated, yields a countable number of separate colonies.

| dilution anaemia | <medicine> An abnormally watery state of the blood; anaemia. Origin: NL, fr. Gr. "ydwr water + blood. Source: Websters Dictionary (01 Mar 1998) |
| dilution cloning | Cloning by diluting the cell suspension to the point at which the probability of there being more than one cell in the inoculum volume is small. Inevitably on quite a few occasions there will not be any cells. (18 Nov 1997) |
| dye-dilution curve | Graph of the serial concentrations (dilutions) of a dye, e.g., Evans blue, following its intravascular or intracardiac injection; useful in the diagnosis of congenital cardiac shunts, measurement of cardiac output, and detection of cardiovalvular incompetence. Synonym: indicator-dilution curve. (05 Mar 2000) |

| indicator dilution techniques | Methods for assessing flow through a system by injection of a known quantity of an indicator, such as a dye, radionuclide, or chilled liquid, into the system and monitoring its concentration over time at a specific point in the system. (12 Dec 1998) |
| aortic ultrasound | An ultrasound examination of the aorta to determine its size, shape and course. The diagnosis of abdominal aortic aneurysm can be made using this test. (27 Sep 1997) |
| breast ultrasound | <investigation, radiology> A test which uses ultrasonic waves to scan the breast. Used to evaluate fibrocystic breast disease, breast implants or breast masses. (27 Sep 1997) |
| carotid ultrasound | <investigation> A noninvasive test which uses high-frequency sounds waves to determine extent of blood flow through the carotid arteries in the neck. Used in the evaluation of stoke and TIA symptoms. (08 Jan 1998) |
| cysts by ultrasound | <radiology> Defined by three properties (all must be present): anechoic lumen, sharp posterior margin, posterior acoustic enhancement (12 Dec 1998) |
