What is MRI?
Magnetic resonance imaging (MRI) is a modern, non-invasive examination method that is used to obtain an image of internal structures of the body. The method is used in brain diagnostics as a tool to diagnose disorders such as congenital disorders, brain tumours, inflammatory changes in brain tissue, adverse demyelinating, and vascular changes in the brain.
The MRI technology is based on registering the effects of magnetic waves. This method enables measurement of the absorption and emission of the waves by a tissue which is placed in a strong magnetic field (~1.5T). After the impact of the magnetic wave stops, the previously magnetized protons return to their initial state and become the source of the signal themselves. Depending on the type of tissue, the signal differs in intensity. Those differences can be recorded, registered and processed into information in the form of a medical image.
The image of the brain structures obtained by this method enables for precise diagnostics.
Nowadays, it has become a priority to create a friendly and calm environment inside the examination room. The person examined is allowed to communicate freely with the control room and has access to entertainment. This method decreases the number of appointments that are moved, cancelled or repeated. It also contributes to the decreased use of anaesthesia during child examinations.
