Medical imaging
Because CT and MRI are sensitive to different tissue properties, the appearances of the images obtained with the two techniques differ markedly. In CT, X-rays must be blocked by some form of dense tissue to create an image, so the image quality when looking at soft tissues will be poor. In MRI, while any nucleus with a net nuclear spin can be used, the proton of the hydrogen atom remains the most widely used, especially in the clinical setting, because it is so ubiquitous and returns a large signal. This nucleus, present in water molecules, allows the excellent soft-tissue contrast achievable with MRI.
National Center for Spinal Disorders
The Radiology Department of the National Center for Spinal Disorders was one of the first to have a direct digital (ddR) x-ray equipment installed in Hungary. This made the entire spectrum of radiological examinations with lower radiation and no x-ray film possible. A 3D/4D ultrasound equipment has been in use since September, 2005. The CT/MRI laboratory also contains a fast 4 slice multisclice CT equipment for examining every region of the body and an open MRI for patients suffering from claustrophobia. Aside from the examination of the skull and the spine, the equipment is excellent for diagnosing musculoskeletal abnormalities, joints and sports injuries.
