| iodinated contrast | A substance that contains iodine that can be injected, swallowed or given as an enema for the purpose of diagnostics. Iodinated contrast is radiopaque. This means that conventional X-rays will highlight the course of the contrast in the body. (27 Sep 1997) |

| areolar tissue | Loose, irregularly arranged connective tissue that consists of collagenous and elastic fibres, a protein polysaccharide ground substance, and connective tissue cells (fibroblasts, macrophages, mast cells, and sometimes fat cells, plasma cells, leukocytes, and pigment cells). (05 Mar 2000) |
| bone tissue | A connective tissue, the matrix of which consists of collagen fibres and ground substance and in which are deposited calcium salts (phosphate, carbonate, and some fluoride) in the form of an apatite. Synonym: bone tissue. (05 Mar 2000) |

| brown adipose tissue | A thermogenic type of adipose tissue containing a dark pigment, and arising during embryonic life in certain specific areas in many mammals, including man. It is prominent in the newborn of all species in which it occurs and remains a distinct and conspicuous tissue in the adults of certain species, especially those that hibernate. It is also called brown adipose tissue. (12 Dec 1998) |
