MRI of the skull bones
A long proven method of ray examination of the skull is plain radiography. The skull has a complex anatomical structure, whereby the image of the bones and their parts intertwine. Therefore doctors prefer to do MRI to better visualize the individual bones. In particular, this affects the underlying bone and facial region of the skull.
Leading position in the diagnosis of diseases of the facial Department of the skull, brain and meninges in modern clinical medicine occupies an MRI. It is possible to consider the image slices to reconstruct the 3d view of the skull. Thanks to computer processing to obtain an enlarged image of physician interest region. MRI has the advantages not only to x-rays, but before computed tomography. On MRI tomograms clearly distinguished the smallest structures of our brains, their not affected by reflecting the influence of the skull bones, which spoils the quality in computer tomography. The CT scan can obtain images only in direct projection, and in MRI in axial, frontal, sagittal planes, and in oblique sections. Another advantage of MRI, which has neither CT nor radiography – no radiation exposure and safety for the patient.
- Fractures of the zygomatic bone.
- Foreign body in the area of damage.
- Malignant/benign tumors.
- Metastases to bones of the facial Department of the skull.
- Pathology of the jaw apparatus.
- Inflammatory diseases of maxillo-facial apparatus.
- Examination of the bones of the skull and brain before surgery.
Conditional contraindications for study and condition, excluding the use of MRI diagnostics fully
To do magnetic resonance imaging of the skull bones is impossible, if the body of the patient have any metal parts that cannot be dismantled. Such as an insulin pump, surgical metal braces, artificial pacemaker. This poses a threat to human life: the effects of EMFs (electromagnetic influence) disrupted heart pacemakers, and fixed elements-ferromagnetic materials may shift in the body of the patient due to the heating by the field. But the medical products made from paramagnetic, do not move, do not heat up under the action of EMFs.
MRI with a titanium plate can do!
If any part of the body of a patient fitted with the prosthesis, staples, pins or a plate of titanium – this is not a contraindication for the study. Same deal with the brackets: you will need to ask your dentist what material they are made, can you do an MRI. If paramagnetic, this does not prevent the procedure. MRI with braces, made of ferromagnetic materials is not dangerous for patient’s life and it is theoretically possible, but it greatly increases the likelihood of diagnostic errors. This is especially true of MRI of the facial Department of the head and skull as a whole: braces fall into the area of research and worsen the visualization, creating artifacts.
During pregnancy and feeding it is impossible to do MRI with contrast because the contrast can have a harmful effect on the fetus and newborn. Renal pathology is also a reason to abandon the procedure from the list as impaired excretion of contrast agent from the body. As a rule, before the first MRI procedure using contrast, you need to do Allergy test, because in some people the drug may cause allergic reaction.
Is it possible to study children? Yes, it is safe. But a conditional limitation is the age of seven years, as all the research you need to lie still.
What happens after you sign in magnetic resonance imaging?
There is no preparation for an MRI of the bones is not required. Before you lie on the scanner couch, you need to remove jewelry, remove from hair pins, barrettes, to get pockets credit cards, keys, meaning that all metal objects. When you lie on a couch, the head is fixed cushions to prevent accidental movement, and a couch enters the inside of the machine. The device when working makes a noise that does not indicate malfunction. The study itself takes about an hour, but with the use of contrast may take a little more time.
Savings or health?
Today unlikely to find a more affordable and secure for most people, and more informative for doctors method than MRI. Injuries of the skull bones, especially the facial region (which is responsible for the aesthetic side) not timely diagnosed and nepodvizhnye therapy are fraught with danger for human health in the future. Resorting to an MRI, you can avoid complications and costly surveys that they entail.
