Question: Went for MRI cause have swelling on my left temple and hurt in back of my head. Report came back saying: There is Mucoperiosteal Thicking in the right Maxillary Antrum. They wrote down the right but I am reading that on the MRI the Right side really means the left side. Could you explain what they are talking about. My left temple hurts really bad. My memory is very good, and so is my health. On no medication.Two weeks agot when I was sleeping I woke up and my left temple really hurt. Felt like blood vessel broke and I have hurt ever since.

Brief Answer:
The on screen display is from foot end of the MRI scanner

Detailed Answer:
Hi,
Thanks for writing in to us.

In MRI scan protocols for the head area, the patient is imaged lying on the couch on their back and the head end is towards the gantry and the foot end is away.

When we study the images, it is assumed that we are looking at the images from the foot end of the MRI scanner and this is an universal assumption.

**Under special circumstances like MRI breast mammography, the images may be obtained in different positions and later modified to display it showing the right of the image to the left of the individual of the viewer.

Keeping in mind the conventional rules, the right of the patient is to the left of the viewing screen. Therefore if you are looking at MRI scan images of your brain and sinuses then the right side of brain and face will to your left.

You might also find (R) mentioned on the screen showing the right side on the image. This is also an universal convention to avoid confusions.

Coming to your problems, I understand there you have a mild inflammation of the right maxillary sinus and this is a commonly found condition.

Concerning the pain in the left temple, it is possible that a condition involving the trigeminal or facial nerves on the left can give you such symptoms and not all causes are evident on a MRI scan.

Please do write back with your doubts.
