Skull MR scan
MR imaging is one of the most modern diagnostic tests. Using a magnetic field, it provides a more accurate and detailed picture of the structures being examined than any other technology (X-ray, CT). MR scans of the skull provide the most detailed images of the brain chambers and the grey and white matter that make up the brain, the brain nerves and the cerebral circulation.
When is a skull MRI scan recommended?
A skull MRI scan is done for neurological complaints or on the recommendation of a neurologist. The scan may be needed in cases of headache, dizziness, nausea, tinnitus, sensory or motor problems, impaired cognitive function, memory, or possibly speech impairment. Native tests have no adverse health effects and can be used as a screening test or to rule out hereditary conditions.
These symptoms can be caused by a number of conditions and problems, including:
- A variety of benign and malignant tumour lesions
- Neurodegenerative diseases (multiple sclerosis, Alzheimer’s disease, Parkinson’s disease)
- Cerebral trauma
- Cerebral vascular damage (stroke, cerebral atherosclerosis)
- Epilepsy
MR scans are also excellent for diagnosis and follow-up of already diagnosed diseases.
What should you know about skull MRI?
Cranial MR scans are performed in the supine position and take 20-30 minutes, during which time complete immobility is required. This position and the scanning device around the head may cause some discomfort. You should also not talk during the examination, as this will cause the head to move and distort the imaging.
Tests can be performed natively or using contrast media.
Within the cranial region, scans can be performed for different diseases or for targeted areas.
We perform examinations in the following regions:
- whole skull MR
- cranial MRI and MRA (3D TOF MR angiography – scan targeting native cerebral arteries)
- face skull MR
- inner ear MR
- sella, pituitary gland MR
- orbita – eye socket MR
MR of the skull, MRA (MR angiography, examination of non-contrast cerebral blood vessels) is recommended for headache, dizziness, migraine complaints.
The pituitary gland is performed for hormonal problems (microadenoma, macroadenoma) with the administration of contrast medium. The orbit of the eye can be examined for problems of the eye muscles and optic nerves; the facial cranium can be examined for sinuses of the nose for inflammations. In case of tinnitus and rotational vertigo, the cranial area is examined for the ear region, targeting the inner ear.
A special scan can be done for Multiple Sclerosis(MS) using contrast material.
Discomfort may also be caused by the loud sounds emitted by the machine, but earplugs and ear protection can reduce the problem.
The test does not require any special preparation, but fluid intake should be monitored. If a contrast agent is to be used, fasting for 4-6 hours, a preventive renal function laboratory and a 2-day absence of diabetic medication before the test are also necessary.
