Brain MRI is a highly accurate imaging exam that allows detailed assessment of the brain, meninges, intracranial vessels and adjacent bony structures. It is a non-invasive, radiation-free exam indicated in cases of neurological symptoms, tumours, vascular changes or inflammatory diseases of the central nervous system.
What is a Brain MRI?
Brain MRI is an exam that uses magnetic fields and radiofrequency waves to generate detailed images of the brain and surrounding structures. Because it does not use ionising radiation, it is a safe and effective option for diagnosing neurological conditions, infections, tumours, vascular malformations and demyelinating diseases.
How much does a Brain MRI cost?
The price of a brain / head MRI is 275€ when performed on a self-pay basis. However, you can also have it done through several agreements, including:
- ADSE: If the brain / head MRI is performed through ADSE, the patient only pays the copayment of 30€;

How is a Brain MRI performed?
The patient is first prepared with the placement of a venous catheter if the scan is going to be performed with contrast. Then, they are positioned lying on their back, with the head stabilised inside a dedicated brain coil to ensure the region remains still.
The exam usually lasts between 30 and 40 minutes.
Earplugs are provided to reduce the perception of noise from the equipment.
The MRI scanner is open at both ends.
What does it detect?
Brain / head MRI can detect:
- Benign or malignant brain tumours;
- Strokes, haemorrhages or ischaemia;
- Demyelinating lesions (e.g. multiple sclerosis);
- Vascular malformations (aneurysms, arteriovenous malformations);
- Infections, abscesses or inflammation of the central nervous system;
- Cerebral oedema, hydrocephalus or changes in the subarachnoid space;
- Degenerative or traumatic conditions;
- Among others.
When is a Brain MRI indicated?
Brain / head MRI is indicated, for example, in cases of:
- Persistent or unexplained headaches;
- Neurological changes such as epilepsy, sensory or motor loss;
- Suspected primary or metastatic brain tumours;
- Post-stroke assessment;
- Suspected multiple sclerosis or other demyelinating diseases;
- Cerebral vascular abnormalities;
- Monitoring of known lesions or neurological treatments;
- Among others.
Preparation and instructions for a Brain MRI
Before having an MRI at NRD, please take the following into account:
| Topic | Instruction |
| Exam prescription (paper copy) | You must bring the paper copy of the exam prescription with you. |
| Fasting | Most MRI scans do not require fasting. When contrast is needed, fasting for about 3 hours is usually required (this will be confirmed when you book the exam). |
| Arriving early | Please arrive 15 minutes before your scheduled appointment time. |
| Medication | You may take any important and unavoidable medication with a small amount of water. |
| Metal objects | Remove all metal objects (e.g. earrings, bracelets, necklaces, piercings, hairpins, removable dentures, etc.). |
| Pregnancy | Inform the NRD healthcare professional if you are pregnant. |
| Previous exams / tests / information | Bring previous imaging exams, relevant clinical information and recent blood test results. |
| Glucose monitoring implant | Do not apply the implant, as it will have to be removed before the exam. |
| Make-up | Do not wear make-up, as some products may interfere with the exam. |
| Valve and/or orthopaedic prostheses | If you have valve and/or orthopaedic prostheses, bring documentation describing and identifying the material. |
| Hearing aids | Inform us if you use a hearing aid, as it will need to be removed before the exam. |
| Dental prostheses | Inform us if you use a dental prosthesis, as it will need to be removed before the exam. Also let us know if you have dental implants. |
| Orthodontic appliances | Inform us if you have an orthodontic appliance. It may be necessary to perform a compatibility test for MRI. |
| Pacemakers and implanted devices | NRD does not perform MRI scans on people with pacemakers or implanted devices (e.g. cochlear implants). In these cases, the exam should preferably be done in a hospital setting. |
Throughout the entire MRI exam, you will be continuously monitored by the NRD imaging technologist responsible for your scan. You will also have an alert system at your disposal that you can activate if needed.
You must remain still during the exam to ensure high-quality images.
The entire NRD team will be available to answer any questions you may have.
After the exam, you can resume your usual daily activities.
When and how will you receive your results?
You will receive your MRI results within up to 7 days after the exam, by email or on paper at the clinic. On the day of the exam, you will take home a CD with the images.
