MRI takes advantage of the fact that if a strong magnet is applied to the human body, its water molecules (hydrogen atoms, to be precise) arrange themselves in parallel. When radio waves hit these parallel hydrogen nuclei, their orientation changes. After the radio wave pulse subsides, they return to their initial parallel position. The extent of this deflection can be recorded and a computer can convert the data into layered images.
By means of these MRI images, doctors can diagnose diseases and injuries of organs, soft tissues and other tissues very well. Hard structures such as bones or joints can also be displayed. Depending on their water content, the structures and tissues appear lighter or darker on the MRI images.
Radiologists often work with a contrast medium containing gadolinium, which they inject into the vein. This enables them to distinguish different tissues even better, for example in the case of tumors, inflammation, signs of wear and tear, or injuries.
In neuroradiology MRI is used to diagnose a wide variety of diseases and injuries. Some examples:
- Diseases of the brain, e.g. stroke, brain tumors, vascular malformations, inflammations, injuries after accidents.
- Diseases of the spinal cord
- Vascular changes in arteries and veins, e.g. constrictions or occlusions
- Joint diseases, intervertebral disc wear, vertebral body fractures
Magnetic resonance imaging can also be combined with other examination methods. One example is positron emission tomography (PET-MRI, e.g. for cancer).
