Sarah's doctor recommends that she get an mri to diagnose the cause of her headaches. the doctor provides a list of mri facilities. which is an indicator that a facility is a poor choice for sarah ?

The facility accepts most health insurance policies but not Sarah’s.

Explanation:

Magnetic resonance imaging is an expensive medical procedure and for this reason Sarah would need the support of health insurance to cover the expenses of the procedure. A facility that does MRI procedures is only a good option for Sarah if that facility accepts Sarah's health insurance policy, otherwise she should look for another facility.

The MRI machine has a large magnet that interacts with our body through magnetic fields and radiofrequency pulses. This creates high definition images in three planes: horizontal, vertical and layered. Even because it does not emit radiation and is very complete, the exam has a relatively high cost.
