Whole-body MRI allows us to visualize the entire body, i.e., all organs, the skeletal system, the spine, the vascular system, and the joints. The examination is primarily used for the early detection of certain types of cancer. Depending on age and genetic or individual predisposition, other issues, such as possible narrowing of blood vessels, can also be investigated. The examination does not replace a gastrointestinal endoscopy or a dedicated lung examination. The examination does not require X-rays.
