Mri with metalic braces. Braces.

Doctor I have cyst in brain. I consulted 2-4 neurologist till 2017 . 2 neurologist suggest me to remove that cyst to avoid pain ,3 neurologist suggestion was that cyst is dried never impact , u can go for braces but done MRI of brain every 2 year to monitor growth of arachnoid cyst . I am facing strong uncontrolled headache once in 15 days. And that time I use pain relief gel in large quantity ( 20 gm omini gel tube can be empty after 2-3 session) . Currently I am facing strong tingling daily , extreme weakness and body pain. I am placed in one IT company, I may need to relocate  myself to other city for training purpose. Till I hadn't not diagnosis MRI due to dental brace. My dental treatment is not competed yet, but I want to rule out my brain cyst growth. Can I undergo ct-scan/ mri with metallic braces.
