What is Cranio-Cerebral MRI and how does it works?
Cranio-Cerebral MRI is a painless, non-invasive and non-irriadiated investigation that helps the doctor diagnose certain pathologies. It uses a powerful magnetic field and radio waves, which it processes computerized, providing images of the brain and the skull structures, more clearly and more detailed than other imaging methods. In some cases, it may be necessary to inject a contrast substance, called Gadolinium, which is likely to produce less allergic reactions compared to those contrast agents containing Iodine.
When is Cranio-Cerebral MRI used?
It can be used to detect certain pathologies, the most common of them being:
– Cerebrovascular accidents, both ischemic and haemorrhagic
– Brain tumors
– Cranio-cerebral development abnormalities
– Some causes of epilepsy
– Multiple sclerosis
How to prepare yourself and how will the examination take place?
You can eat and take your medications according to your daily schedule before the examination, unless otherwise indicated.
Since you are under the influence of a strong magnetic field, it is recommended to remove your jewelry, clocks, cards, hearing aids, dentures, hair clips or any other metallic accessories before the examination.
You will sit on the exam table and you will be asked to sit tight as much as possible while capturing the images.
Tell your doctor if you have implants or medical devices in your body. In many cases, MRI is safe for patients with new-generation of metallic implants, but patients with cochlear implants and almost all pacemaker carriers can’t carry out the investigation.
If it is necessary to inject a contrast agent, tell the radiologist if you suffer from any kind of allergies (food, medicine) or if you suffer from asthma. It is also important to mention if you have a kidney disease.
Although the MRI investigation has been in use since the 1980s, with no reports of adverse effects on pregnant women or unborn babies, examination is not performed on women in the first 3-4 months of pregnancy unless in limited cases.
