Long-scale contrast
A radiograph that demonstrates small differences in density between adjacent areas. Long-scale contrast is a result of high kilovoltage peak (kVp). In dental radiography, for example, 80 to 90 kVp or higher is necessary to produce a radiograph with long scale contrast. The implementation of an elevated Kv.P. range yields a diverse range of nine…

Image receptor contrast
The characteristics of an imaging medium that influence the ability of the radiologist to see differences in density between adjacent objects in the image.
-
Contralateral reflex
Passive flexion of one part following flexion of another.
-
Pseudomyostatic contracture
Apparent permanent contraction of a muscle due to a central nervous system lesion, resulting in loss of range of motion and resistance of the muscle to stretch.
-
Physiological contracture
A temporary condition in which tension and shortening of a muscle are maintained for a considerable time although there is no tetanus. It may be induced by heat, illness, drug action, or acids.
-
Functional contracture
Contraction of a muscle that decreases during anesthesia or sleep.
-
Fibrotic contracture
Contraction of a muscle in which the muscle tissue has been replaced by fibrous tissue because of injury.
-
Contract research organization
Any privately financed, for-profit entity that performs industry-sponsored biomedical research. Health research is conducted in government sponsored laboratories, e.g., the National Institutes of Health or the Center for Disease Control and Prevention; academic medical centers (such as those affiliated with a major university hospitals), and CROs.
-
Tonic contraction
Spasmodic contraction of a muscle for an extended period.
-
Tetanic contraction
Continuous muscular contraction.
