Diagnostic ServicesDiagnostic imaging refers to technologies that doctors use to look inside your body for clues about a medical condition. A variety of machines and techniques can create pictures of the structures and activities inside your body. The technology your doctor uses will depend on your symptoms and the part of your body being examined. X-rays, CT scans, nuclear medicine scans, MRI scans and ultrasound are all types of diagnostic imaging. Many imaging tests are painless and easy. Some require you to stay still for a long time inside a machine, though. This can be uncomfortable. Certain tests involve radiation, but these are generally considered safe because the dosage is very low.
