In epilepsy care, MRI plays a key diagnostic role, particularly due to its ability to precisely visualize the brain’s structure and identify epileptogenic lesions that may be the source of seizures. This information is essential for accurate diagnosis and treatment planning.
The MRI machine is a large, cylindrical device open at both ends. Inside, the magnetic field and radio waves interact with hydrogen atoms in your body to produce cross-sectional images, which appear on a monitor. MRI does not use ionizing radiation, making it a safe procedure in terms of exposure risk. The scanner can also generate 3D images, viewable from multiple angles.
What Happens During the Exam?
The MRI itself is painless, but the scanner produces loud knocking and banging noises during the imaging process. You will be given earplugs or headphones, and in some cases, you may be able to listen to music to reduce discomfort.
- You will lie down on a motorized table that slides into the scanner tube.
- The radiologic technologist will monitor you from an adjacent room, but you’ll be able to communicate via speakers inside the scanner at any time. You will also be able to speak to them if needed during the procedure.
- After the scan, the table will move out of the machine and the technologist will assist you in getting up.
How Long Does It Take?
An MRI scan may take anywhere from 15 minutes to over an hour depending on the complexity. A specialized epilepsy protocol (EPI protocol) typically takes about 35 minutes.
Where Can You Have an MRI?
Even if you’ve had an MRI at another facility in the past, a more precise scan using an epilepsy-specific protocol may be needed to make an accurate diagnosis.
MRI can be performed as an outpatient exam or during hospitalization, depending on your needs and clinical condition.
Adult Patients
You will be scheduled for an MRI either during your visit to the epilepsy outpatient clinic or during hospitalization as part of your diagnostic workup.
For outpatient MRI, your treating neurologist will issue a referral and explain the booking process in detail. MRI examinations at St. Anne’s University Hospital (FNUSA) are performed in Buildings B1, O1, or M. The specific location will be provided when your appointment is scheduled.
If you are unsure about where your scan will take place, you can contact the MRI scheduling office at: +420 54318 3027
In certain cases—particularly as part of pre-surgical evaluation for epilepsy surgery—a special high-resolution MRI scan may be required. This exam is performed outside FNUSA at the Central European Institute of Technology of Masaryk University (CEITEC MU), located at:
Kamenice 735/5, Brno-Bohunice, Masaryk University Campus (entrance from Studentská Street)
This advanced imaging helps to refine surgical planning by providing detailed visualization of brain structures critical to the success and safety of epilepsy surgery.
Paediatric Patients
Your child may be referred for an MRI either during an outpatient consultation or during hospitalization.
For children approximately up to the age of 6, the MRI scan is typically performed under general anesthesia, as they are unlikely to remain still for the duration of the procedure.
MRI for pediatric patients can be scheduled at the Children’s Hospital by calling: +420 532 234 546
Available Monday to Friday between 7:00 AM and 2:30 PM.
If your child is referred for a 3T MRI scan, the examination will take place using the 3 Tesla MRI machine at St. Anne’s University Hospital (FNUSA), which provides high-resolution imaging required for more advanced diagnostic needs.
