The temporal bone covers the area of the ear and the face. The diseases of these regions can be determined through magnetic resonance imaging.
The assessment of the temporal bone is a difficult task. Therefore, radiologists use magnetic resonance imaging to evaluate the temporal bone. MRI is better than computed tomography because it does not use ionizing radiations. Instead, strong magnetic waves help in viewing the pictures of the internal parts. With the help of MRI, the radiologist can study middle ear diseases. Some of these diseases include ear pain, hearing problems and inflammation. MRI is a simple and painless procedure.
The radiologist in the following steps performs MRI scan:
- The patient wears a comfortable, loose gown.
- The radiologist makes the patient lie down on a table.
- The table moves within the machine where a strong magnetic field exists.
- The radiologist may also place a coil or frame near the concerned part of the body.
- The machine takes down multiple pictures from different angles.
- After the scan, the table moves out of the machine.
The whole procedure may take 15-90 minutes to complete.
Risks involved with this method are:
- Due to high magnetic intensity, the scan may affect any metal parts in the body.
- The strong magnetic field may hamper foetus development.
- A patient may feel dizziness after the MRI.
Before the scan takes place, the patient needs to keep in mind the following:
- Inform the doctor about pregnancy.
- Remove jewellery and accessories.
- Remove any metal implants like fake teeth.
- Inform the doctor if there are some metal parts in the body.
- Inform the doctor about certain allergies.
- Do not undergo the test if the body has pacemakers or artificial valves.
After the test, the post care treatment includes:
- The patient can resume normal activities and diet.
- Follow the instructions given by the doctor carefully.
