Bone fixation is a surgical procedure that stabilizes and fix bone grafts and bone filling materials for the regeneration of bone. Bone fixation screws are especially used for internal bone fixation.
Bone densitometer is an advanced form of X-ray technology that is used for the measurement of bone loss. Bone loss is measured by using established bone mineral density measuring standards.
Contrast media (or contrast agents) is a substance used to increase the contrast of structures or fluids within the body in medical imaging. Contrast agents absorb or alter external electromagnetism or ultrasound, which is different from radiopharmaceuticals, which emit radiation themselves. Contrast media, enhance the radiodensity in a target tissue or structure.
Contrast agents are commonly used to improve the visibility of blood vessels and the gastrointestinal tract.
Several types of contrast media are in use in medical imaging and they can roughly be classified based on the imaging modalities where they are used. Most common contrast agents work based on X-ray attenuation and magnetic resonance signal enhancement.
Contact Lenses (CLs) are lightweight corrective, cosmetic or therapeutic devices that are usually placed directly onto the cornea of the eye. Contact lenses have many benefits for wearers, including appearance and practicality. Many people choose to wear contact lenses as opposed to eyeglasses as they do not steam up, they provide a wider field of vision, and they are more suitable for a number of sporting activities.
