The electrode on the needle picks up the electrical activity given off by your muscles. This activity appears on a nearby monitor, and may be heard through a speaker. After placement of the electrodes, you may be asked to contract the muscle. For example, bending your arm. The electrical activity seen on the monitor provides information about your muscle's ability to respond when the nerves to your muscles are stimulated. A nerve conduction velocity test is usually performed along with an EMG.

Brain cells communicate with each other by producing tiny electrical impulses. In an EEG, this faint electrical activity is measured by putting electrodes on the scalp. The test is performed by an EEG technician in your health care provider's office, at a hospital, or at a laboratory. You will be asked to lie on your back on a bed or in a reclining chair. The technician will place between 16 and 25 flat metal disks (electrodes) in different places on your scalp. The disks are held in place with a sticky paste. The electrodes are connected by wires to an amplifier and a recording machine. The recording machine converts the electrical impulses into patterns that can be seen on a computer screen and stored on a computer disk. Before computers, the activity was printed on paper. In either case, the electrical activity looks like a series of wavy lines. You will need to lie still with your eyes closed because any movement can change the results. You may be asked to do certain things during the recording, such as breathe fast and deeply for several minutes or look at a bright flashing light.

A mammogram is a special type of X-ray of the breasts. Mammograms can show tumors long before they are big enough for you or your health care provider to feel. They are recommended for women who have symptoms of breast cancer or who have a high risk of the disease. You and your health care provider should discuss when to start having mammograms and how often to get one. Mammograms are quick and easy. You stand in front of an X-ray machine. The person who takes the X-rays places your breast between two plastic plates. The plates press your breast and make it flat. This may be uncomfortable, but it helps get a clear picture. You will have an X-ray of each breast. A mammogram takes only a few seconds and it can help save your life. A mammogram is an x-ray picture of the breasts. It is used to find tumors and to help tell the difference between noncancerous and cancerous (malignant) disease.

An OPG machine is specially constructed so that it rotates around the jaw bones, thus giving us an extremely good idea about the structure of the jaw bones. Yes, X-rays are used, but the method is totally different. OPG X-rays are usually asked for by the dentists, whether they are general dentists, orthodontists, oral surgeons or prosthodontists implantologists. Because OPGs give a holistic view of the teeth and the adjacent bones, they are useful in a wide variety of conditions including infections, tumors, congenital abnormalities, pre-implant evaluation and trauma.
