Diagnostic ultrasound, also called sonography or echosonography, is an imaging method that uses mechanical sound waves to generate images of structures inside your body. Images can provide valuable information to diagnose and guide the treatment of many diseases and conditions.
Magnetic resonance imaging (MRI or MR) is a medical imaging technique that uses a magnetic field and computer-generated radio waves to create detailed images of the organs and tissues in your body. An MRI scan differs from CT scans and X-rays in that it does not use potentially harmful ionizing radiation.
A CT scanner or computerized tomography is a modern diagnostic device that uses X-rays to form an image of the whole body, which provides detailed information about pathological changes in the body. The multislice scanner has a large number of X-ray detectors that pass through the body, making the examination much faster and more accurate.
X-ray imaging is a diagnostic procedure based on X-rays.
