MR of the orbits
Magnetic resonance imaging is a non-invasive test used to image the human body. It is often used as an adjunct to a previously performed CT scan or other imaging studies such as ultrasound. MRI has the advantage of better resolution between different soft tissues, making it the procedure of choice for imaging the soft tissues of the brain and orbit. MR is one of the finest imaging techniques currently available in medicine.
A number of procedures performed with magnetic resonance imaging require the administration of a contrast agent (sk), but in many cases this is not necessary. Many times the decision to administer contrast is made during the examination.
Sometimes, however, in order to make the imaged structures even more clearly visible, mainly in order to eliminate the proliferative process or other pathological changes – which, after all, in the case of orbits are often very small – the aforementioned contrast is used during the examination.
Indications: to perform MR examination of the orbits
- suspected proliferative process,
- evaluation of intraocular lesions,
- oculomotor assessment,
- visual disturbances,
- headaches,
- post-trauma condition,
- Diagnosis of demyelinating diseases such as MS,
- many more…
What are the contraindications to orbital MRI?
The presence of a strong electromagnetic field makes patients with objects permanently placed in the body, such as:
- insulin pump,
- cochlear implant,
- neurostimulators,
- pacemaker,
- implants, endoprostheses, stabilizers, plates and orthopedic screws that are made of ferromagnetic materials, that is, materials that resonate in an electromagnetic field. If they are made of titanium, for example, the test can be performed.
Preparation for the study:
- Be sure to provide all medical records for the area to be examined.
