MRI of the jaw generates detailed images of both the soft tissue and bony surfaces. It is commonly used to evaluate the meniscus in the TMI joints (Temporomandibular joint), changes in the structure of the cartilage indicative of injury or age-related degeneration and to examine the trigeminal nerve and soft tissues surrounding.
Temporomandibular joint MRI is also beneficial in surgical planning of the lower face.
Contrast (dye)
Some symptoms and illnesses can be hard to detect even on a MRI scan and require injection of dye (contrast) before or during the scan.
It is particularly helpful in the following conditions:
- Tumours
- Inflammation
- Blood vessels
- Distinguishing between scar tissue and normal organ tissue
The injection is considered very safe for most and you will complete a safety questionnaire detailing your medical history before. The contrast agent (dye) is Gadolinium based and most of it is removed by your kidneys within the next day.
