| contraceptives, oral, sequential | Drugs administered orally and sequentially for contraceptive purposes. (12 Dec 1998) |
|---|---|
| sequential | Occurring in sequence. (05 Mar 2000) |
| sequential analysis | A statistical method that allows an experiment to be ended as soon as a result of desired precision is obtained. (05 Mar 2000) |
| sequential hermaphrodite | <biology, zoology> A type of hermaphrodite which starts out life as one sex and will either turn into a member of the other sex at a later point in life or will be capable of doing so if an appropriate condition arises (for example: the removal of all of the males in a population triggers the most dominant female to become a male). (11 Jun 1998) |
| whole-body irradiation | Irradiation of the whole body with ionizing or non-ionizing radiation. It is applicable to humans or animals but not to microorganisms. (12 Dec 1998) |
| cranial irradiation | The exposure of the head to roentgen rays or other forms of radioactivity for therapeutic or preventive purposes. (12 Dec 1998) |
| hemibody irradiation | Irradiation of one half or both halves of the body in the treatment of disseminated cancer or widespread metastases. It is used to treat diffuse metastases in one session as opposed to multiple fields over an extended period. The more frequent treatment modalities are upper hemibody irradiation (uhbi) or lower hemibody irradiation (lhbi). Less common is mid-body irradiation (mbi). In the treatment of both halves of the body sequentially, hemibody irradiation permits radiotherapy of the whole body with larger doses of radiation than could be accomplished with whole-body irradiation. It is sometimes called "systemic" hemibody irradiation with reference to its use in widespread cancer or metastases. (p. Rubin et al. Cancer, vol 55, p2210, 1985) (12 Dec 1998) |
| prophylactic cranial irradiation | Radiation therapy to the head to prevent cancer from spreading to the brain. (12 Dec 1998) |
| irradiation | Treatment by ionising radiation, such as X-rays or radioactive sources such as radioactive iodine seeds. See: radiation therapy. (16 Dec 1997) |
| total body irradiation | Radiotherapy often given in several doses prior to bone marrow transplantation with the aim of killing any residual leukaemia in the patient. It is used in conjunction with high-dose anti-cancer drugs. The procedure and its side-effects will be discussed individually with the patient. (13 Nov 1997) |
| lymphatic irradiation | External or interstitial irradiation to treat lymphomas (e.g., hodgkin's and non-hodgkin's lymphomas) and lymph node metastases and also some autoimmune diseases, such as rheumatoid arthritis. (12 Dec 1998) |
| anterior inferior segmental artery of kidney | Origin, anterior branch of renal. See: segmental arteries of kidney. Synonym: arteria segmenti anterioris inferioris renis, artery of anterior {inferior segment of kidney}. (05 Mar 2000) |
| anterior superior segmental artery of kidney | Origin, anterior branch of renal. See: segmental arteries of kidney. Synonym: arteria segmenti anterioris superioris renis, artery of anterior {superior segment of kidney}. (05 Mar 2000) |
| branches of segmental bronchi | Branches of segmental bronchi to the bronchopulmonary segments of the lungs. Synonym: rami bronchiales segmentorum. (05 Mar 2000) |
| mastectomy, segmental | Removal of only enough breast tissue to ensure that the margins of the resected surgical specimen are free of tumour. (12 Dec 1998) |
