The inner ear is located at the end of the ear canals, deep within the temporal bone and behind the eardrum, a scan is the only non-invasive way to evaluate the area.
MRI of the internal and external part of the ear provides a detailed study of the organ morphology and can be helpful in the diagnosis of vestibular disorders, such as inflammation (otitis) or blockage.
The inner ear is responsible for balance and disorders affecting this area can be very debilitating. Other indications for an MRI are a tinnitus, hearing deficiency or pain that can sometimes mimic jaw pain.
Initial MRI scans of the internal ear are often contrast (dye) enhanced.
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.
