| ultrasonic cardiography | Echocardiography is a diagnostic test which uses ultrasound waves to make images of the heart chambers, valves and surrounding structures. It can measure cardiac output and is a sensitive test for inflammation around the heart (pericarditis). It can also be used to detect abnormal anatomy or infections of the heart valves. (12 Dec 1998) |
| ultrasonic cephalometry | Measurement of the foetal head by ultrasound. (05 Mar 2000) |
| ultrasonic egg recovery | Obtaining an egg for in vitro fertilization by means of an ultrasonically guided needle aspiration of ovarian follicles; may be performed transvesically or via the cul-de-sac. (05 Mar 2000) |
| ultrasonic lithotresis | The demolition of calculi by high frequency sound waves. (05 Mar 2000) |
| ultrasonic microscope | <instrument> A microscope that has lenses designed to use acoustic energy so that the ultrasonic wavelengths may be utilised; by means of transducers, the information is translated to a form that may be visualised or recorded. (05 Mar 2000) |
| ultrasonic nebuliser | A humidifier using high-frequency electricity to power a transducer that vibrates 1,350,000 times per second and changes water up into particles 0.5 to 3 um in size in its nebulizing chamber; used in inhalation therapy. (05 Mar 2000) |
| ultrasonic rays | See: ultrasonic. (05 Mar 2000) |
| ultrasonic scaler | An ultrasonic instrument that uses high frequency vibration to remove adherent deposits from the teeth. (05 Mar 2000) |
| ultrasonic waves | The periodic configuration of energy produced by sound having a frequency greater than 30,000 Hz. (05 Mar 2000) |
| acupuncture therapy | Treatment of disease by inserting needles along specific pathways or meridians. The placement varies with the disease being treated. Heat or moxibustion and acupressure may be used in conjunction. (12 Dec 1998) |
| adjuvant therapy | <oncology, pharmacology> Treatment that is added to increase the effectiveness of a primary treatment. In cancer, adjuvant treatment usually refers to chemotherapy, hormonal therapy or radiation therapy after surgery to increase the likelihood of killing all cancer cells. (14 May 1997) |
| alternative therapy | A term given to nonconventional therapy usually given by persons who do not have a medical qualification. (16 Dec 1997) |
| analytic therapy | Short term for psychoanalytic therapy. (05 Mar 2000) |
| Antibody Directed Enzyme Prodrug Therapy | <pharmacology> A method for targeting a drug to a specific tissue, in which the targeting agent and the drug are administered separately. The drug is designed to be inactive (a prodrug) until it is converted by an enzyme, which is the targeting agent. The enzyme is coupled to an antibody that directs it to the tissue of interest. When the enzyme arrives at the tissue, the prodrug is activated only at that site, sparing other tissues from potentially toxic side effects. Acronym: ADEPT (14 Nov 1997) |
