MRI PNS is a stimulation process of the nasal nerves and through rapid echo planar imaging and magnetic fields that are fast-switching.
What is MRI PNS?
MRI PNS or MRI Paranasal sinuses is a scanning process that helps in the treatment of the nasopharynx, paranasal sinuses, and the parapharyngeal space. The technique is also used for the stimulation of other organs by switching the value of electrical resistance or the potential of excitation.
How is MRI PNS performed?
The general procedure of MRI PNS is as follows:
- The patient is made to lie down on a CT examination table.
- When the scanning begins, magnetic fields are changed in the MRI gradient systems to obtain imaging and stimulate the nasal nerves.
- The table moves through the scanners multiple times.
- The patient is strapped down if they have a problem with staying still.
The whole process of MRI PNS takes around 30 to 40 minutes to finish.
Side effects/risks of MRI PNS
There are a few risks and side effects that may be caused by MRI PNS.
- Claustrophobic people might need to be strapped to the table.
- Variations in the magnetic field inside the MRI gradient system might cause headaches.
- Birth defects may take place in case of women going through MRI PNS scan while pregnant.
Preparation before performing MRI PNS
These are the things you need to take care of before an MRI PNS.
- Should avoid eating food from 6 hours before the MRI PNS.
- Should remove all the metals and jewelry from your body before the scanning begins.
- Should avoid any heavy physical activities on the day of the MRI PNS scan.
Post-care after MRI PNS
After your MRI PNS scans and stimulation, your doctor will give you an idea where you paranasal health stands. You can consult to the specialists at mfine online to get your doubts cleared about the process from our highly trained specialists.
