How many tmj mri are allowed per year? because i had done one 6 months ago and i need to do another one , but i am afraid it is too soon. thank you!

No risk: There is no ionizing radiation with mri. So there is no risk. Mri uses powerful magnets. Ct (computed tomography) uses x-rays (ionizing radiation) for its images and that's what you have to worry about.

MRIs of the TMJ: Mris of the tmjs are not rountinely needed unless there is a significant functional disturbance, suspected pathology or progressive structural abnormalities. My first question for you would be; why are you getting mris of your jaw joints? The number of images allowed per year would depend on your particular insurance plan. There is no risk of radiation exposure from mris it is a safe test.

Depends on plan: Often the insurance company has a predetermined number of mri's allowed per year. The doctor or specialist ordering the MRI may need to write a letter of medical necessity to the insurance company to verify why another should be taken. Unfortunately, insurance companies look at the bottom line and often ignore the health of the individual.

No limit: Since MRI does not use any ionizing radiation (like x-rays and CT), there is no limit to the number of MRI scans you can have each year based on safety or health concerns. Repeated scans may be necessary at times, but can be costly. Of course, you should feel comfortable with multiple scans, and maybe you should discuss your concerns with your Doctor.

No radiation: No limit as far as I know. One of the big advantages of the MRI scan is no radiation.
