| non-ionic contrast media | <radiology> A class of radiographic contrast media which do not ionise in solution, thereby decreasing effective osmolarity and toxicity. (05 Mar 2000) |

| otitis media | Infection and inflammation of the middle ear space and ear drum. Symptoms include earache, fever and in some cases, diminished hearing. (27 Sep 1997) |
| otitis media, suppurative | Inflammation of the middle ear with purulent discharge. (12 Dec 1998) |
| otitis media with effusion | Inflammation of the middle ear with a clear pale yellow-coloured transudate. (12 Dec 1998) |
| tunica media | <anatomy> The middle coat of blood vessel walls, composed principally of thin, cylindrical, smooth muscle cells and elastic tissue. It accounts for the bulk of the wall of most arteries. The smooth muscle cells are arranged in circular layers around the vessel, and the thickness of the coat varies with the size of the vessel. (12 Dec 1998) |
| facies articularis talaris media calcanei | Underlies the head of the talus and contributes to the talocalcaneonavicular joint. Synonym: facies articularis talaris media calcanei. (05 Mar 2000) |
| fossa cranii media | A butterfly-shaped portion of the internal base of the skull posterior to the sphenoidal ridges and limbus and anterior to the crests of the petrous part of the temporal bones and dorsum sellae; it lodges the temporal lobes of the brain in the lateral portions, and the hypophysis centrally. Synonym: fossa cranii media. (05 Mar 2000) |
| linea axillaris media | A vertical line intersecting a point midway between the anterior and posterior axillary folds or lines. Synonym: linea axillaris media, linea medio-axillaris, middle axillary line. (05 Mar 2000) |
| adrenal mass | <radiology> Metastasis, most common (especially lung, melanoma), primary adenocarcinoma, large at diagnosis (greater than 5 cm), usually functional (increased corticosteroids most likely to be Cushing's), rapid growth, benign adrenal adenoma, with or without functional, nonfunctional occurs in 2-8% of population, diff from metastasis: MRI (metastasis bright on T2), biopsy, follow, pheochromocytoma, neuroblastoma, myelolipoma, cyst / pseudocyst see also: adrenal calcification, haemorrhage (12 Dec 1998) |
| apperceptive mass | The already existing knowledge base in a similar or related area with which the new perceptual material is articulated. (05 Mar 2000) |
| atomic mass | <chemistry, physics> The mass of an atom relative to other atoms. The present-day basis of the scale of atomic weights is carbon, the most common isotope of this element has arbitrarily been assigned an atomic weight of 12. The unit of the scale is 1/12 the weight of the carbon atom or roughly the mass of one proton or one neutron. The atomic weight of any element is approximately equal to the total number of protons and neutrons in is nucleus (16 Dec 1997) |
| atomic mass unit | <chemistry> One-twelfth the mass of a neutral atom of the most abundant isotope of carbon. (16 Dec 1997) |
| bilateral adrenal mass | <radiology> Acute granulomatous disease (e.g., TB), metastases (bilateral in 15%), pheochromocytoma (bilateral in 10%), adrenal hyperplasia (adenoma), spontaneous adrenal haemorrhage (12 Dec 1998) |
| body mass index | One of the anthropometric measures of body mass; it has the highest correlation with skinfold thickness or body density. (12 Dec 1998) |
| breast mass | <oncology, surgery> A breast lump may be benign or cancerous. Examples of breast lumps include: breast abscess, fat necrosis, fibroadenoma, fibrocystic breast disease and breast cancer. A breast biopsy is the best way to determine the aetiology of a breast lump. Remember, 80 to 85% of all biopsies are benign. (27 Sep 1997) |
