This diagnostic technique is commonly used to help the doctor visualize the patient’s bone structure and any possible injuries or abnormalities such as:
Infections, arthritis, or other bone disease
Assess whether a child’s bones are growing normally
Locate foreign objects (such as pieces of glass or metal) in a wound
Determine whether bones are properly set after treating a fracture
Neuropathy Testing (Sudo Scan)
Sudo Scan is a medical device that has been cleared by the FDA for Neuropathy. It is a galvanic skin response (GSR) test. A GSR test measures changes in the electrical properties of the skin in response to different kinds of stimuli. In GSR, changes in the voltage measured from the surface of the skin are recorded. The main origin of the signal has been suggested to be the activation of sweat glands (sudomotor function).
“Sweat response may be the most sensitive test in detecting distal small fiber neuropathy.” (See publications by Low et al. and Gibbons et al). Eccrine glands that are responsible for sweat response receive a rich supply of blood vessels and are innervated by sympathetic C nerve fibers (autonomic nervous system). These fibers are thin and long, and so can be impaired at the early stage of different metabolic diseases, such as diabetes. Testing sudomotor function can be a fast and accurate method for detecting early stages of neuropathies.
CT examination (also known as a CAT scan) is used to help diagnose and treat foot or ankle problems. A CT is an X-ray device that takes cross sectional images of the body, giving a three-dimensional image. CT scans are often superior to conventional X-rays, as they can more accurately pinpoint a suspected problem.
Common foot problems a CT exam can help diagnose include:
Magnetic Resonance Imaging (MRI)
MRI is sophisticated diagnostic equipment used to diagnose a variety of conditions, including:
MRIs use no radiation. It uses large magnets and radio waves to produce three-dimensional images. MRIs are very good at portraying soft tissues and bones in your feet and ankles.
People with the following conditions may not be good candidates for a MRI:
Conditions that requires a heart pacemaker
Artificial heart valves
Electronic inner ear implants
Metal fragments in eyes
Surgical clips in the head (particularly aneurysm clips)
Individuals with dental fillings or bridges, a replacement hip or knee, or tubal ligation clips are generally safe to have a MRI.
