A skull, or cranium, is a set of bones that make up the head of a vertebrate and keeps all the body parts in the head together. It supports the structures of the face and forms a protective cavity for the brain. MRI is one of the most accurate and frequently used methods used for examining the skull in routine clinical practise.
What is MRI of skull?
MRI of the skull is a test that uses a magnetic field and radio waves to produce detailed pictures of the skull. Sometimes, a contrast material is used to enhance the quality of images obtained through MRI.
How is MRI of skull performed?
A standard MRI test of of skull material consists of the following steps:
- Individual to be tested is positioned on A moveable examination table.
- Radio wave emitter and receiver may be placed around or adjacent to the area of the body being studied.
- An intravenous catheter is inserted if a contrast material is to be used.
- The individual is placed under the magnet of the MRI unit and the test is carried out.
Side effects/risks of MRI of skull
MRI is an extremely safe test. However, a few of the rare risks associated with this test are as follows:
- There is a slight risk of allergy if a contrast material is used.
- Implanted medical device may malfunction during the test if it has any metal content.
- The quality of the images may not be very clear if the individual to be tested finds it difficult to lie perfectly still when the test is carried out.
Preparation before performing MRI of skull
- Instructions are laid out by a technician before the test is pursued.
- Report of all the medications and allergies should be provided to the radiologist beforehand.
- The technician shall be informed about the medical implantations in the body, especially the teeth (since the mouth is a part of the skull) of individual to be tested beforehand.
- Anti-anxiety medication should be given to individuals with claustrophobia.
Post-care after MRI of skull
- Individuals who require sedation to stay still during the test shall be allowed some time to recover.
- Individuals with allergic reaction to contrast material should seek medical attention ASAP.
