| magnetic resonance scanning | A special imaging technique used to image internal stuctures of the body, particularly the soft tissues. An MRI image is often superior to a normal X-ray image. It uses the influence of a large magnet to polarize hydrogen atoms in the tissues and then monitors the summation of the spinning energies within living cells. Images are very clear and are particularly good for soft tissue, brain and spinal cord, joints and abdomen. These scans may be used for detecting some cancers or for following their progress. Acronym: MRI (11 Nov 1997) |

| ventilation perfusion scanning | <investigation, radiology> A nuclear medicine test that involves the inhalation of a radioactive gas and the injection of a radioactive compound into the bloodstream. A special camera measures the radioactive compound and generates a image of the lungs. Comparisons are made between the images generated. Pulmonary embolism can be diagnosed using this procedure. (12 Jan 1998) |
| vq scanning | A nuclear medicine test that involves the inhalation of a radioactive gas and the injection of a radioactive compound into the bloodstream. A special camera measures the radioactive compound and generates a image of the lungs. Comparisons are made between the images generated. Pulmonary embolism can be diagnosed using this procedure.

| scanning | The act of imaging by traversing with an active or passive sensing device, often identified by the technology or device employed. (05 Mar 2000) |
| scanning equalization radiography | An electronically enhanced method of radiography in which a small X-ray beam is scanned over the patient while its attenuation is measured, providing feedback to modulate beam intensity in order to equalise average X-ray film exposure. (05 Mar 2000) |
| scanning speech | Measured or metered, often slow speech. (05 Mar 2000) |
| linker scanning | A type of deletion mutagenesis where the distance and/or reading frame between potentially important regions is maintained by replacement with a synthetic oligonucleotide of known sequence. (05 Mar 2000) |
| air pollutants, environmental | Air pollutants which affect environmental conditions. (12 Dec 1998) |
| carcinogens, environmental | Carcinogenic substances that are found in the environment. (12 Dec 1998) |
| national environmental policy act | A federal law enacted in 1969 that requires all federal agencies to consider and analyse the environmental impacts of any proposed action. NEPA requires an environmental impact statement for major federal actions significantly affecting the quality of the environment. NEPA requires federal agencies to inform and involve the public in the agency's decision making process and to consider the environmental impacts of the agency's decision. (05 Dec 1998) |
| draft environmental impact statement | (DEIS) A draft statement of environmental effects. Section 102 of the National Environmental Policy Act requires a DEIS for all major federal actions. The DEIS is released to the public and other agencies for comment and review. (05 Dec 1998) |
| environmental assessment | (EA) A public document that analyzes a proposed federal action for the possibility of significant environmental impacts. The analysis is required by NEPA. If the environmental impacts will be significant, the federal agency must then prepare an environmental impact statement. (05 Dec 1998) |
| environmental exposure | The exposure to potentially harmful chemical, physical, or biological agents in the environment or to environmental factors that may include ionizing radiation, pathogenic organisms, or toxic chemicals. (12 Dec 1998) |
| environmental health | The science of controlling or modifying those conditions, influences, or forces surrounding man which relate to promoting, establishing, and maintaining health. (12 Dec 1998) |
| environmental illness | A polysymptomatic condition believed by clinical ecologists to result from immune dysregulation induced by common foods, allergens, and chemicals, resulting in various physical and mental disorders. The medical community has remained largely skeptical of the existence of this "disease", given the plethora of symptoms attributed to environmental illness, the lack of reproducible laboratory abnormalities, and the use of unproven therapies to treat the condition.
