A jaw MRI exam typically takes 20–60 minutes. The actual scan sequences run about 15–30 minutes, but allow extra time for registration, positioning, and contrast injection if needed, bringing total appointment time up to an hour or slightly longer. Claustrophobic patients may require additional time for preparation or sedation. Check with your clinic.

Yes, MRI is very effective at detecting many neck (cervical) problems: herniated discs, spinal cord and nerve compression, degenerative disc disease, tumors, infection, inflammation and soft‑tissue injury. It is less sensitive for acute bone fractures or fine bony detail (CT or X‑ray are better). MRI results must be correlated with symptoms, and some metal implants can prevent scanning.

A jaw (TMJ) MRI shows soft-tissue and joint details: disc position and displacement, inflammation, joint effusion, cartilage degeneration and arthritic changes, bone marrow edema and early osteomyelitis. It detects tumors, cysts, abscesses, salivary gland disease, nerve involvement, and muscle or ligament injury from trauma. It’s less sensitive for fine fractures (CT better) but excellent for soft‑tissue and inflammatory pathology.

Price varies by country, facility and whether contrast is used. In the U.S. a jaw/TMJ MRI commonly runs about $400–$3,000 (often $1,000–$2,000 uninsured). In the UK it’s free on the NHS; private scans typically cost ~£200–£700. In India prices can be roughly ₹2,000–₹8,000. Additional fees for radiologist interpretation, urgent appointments or sedation can raise the total.

Most people can safely have an MRI after jaw (orthognathic) surgery. Modern fixation devices and dental implants—usually titanium—are non‑ferromagnetic and MRI‑compatible, though they may cause image artifacts. Older stainless‑steel hardware can be problematic. Always tell the radiology team about prior jaw surgery, bring implant documentation or operative notes, and follow their guidance; they may adjust technique or choose alternatives.

MRI scan times vary by body part and complexity. A single-region MRI typically takes 20 to 45 minutes; detailed studies (for example cardiac or whole-body imaging) can take 45 to 90 minutes. Rapid protocols may be 10 to 15 minutes. Setup, positioning and contrast injections commonly extend total appointment time to about 30 to 90 minutes; patient movement or claustrophobia can lengthen the exam.
