Diagnosing And Treating A Cholesteatoma

Magnetic Resonance Imaging

If a CT scan determines further imaging is required, magnetic resonance imaging can provide even more detail. Unlike a CT scan, an MRI does not use X-rays instead using radio waves and a magnetic field. This technique is noninvasive and can be especially useful for pre- and post-operation. A person is placed within the MRI scanner, and a 3-D image is produced without the use of harmful radiation. This can show precisely where the excess skin of the cholesteatoma is growing, how deep it has progressed, and help to determine the best way to remove it. Using magnetic resonance imaging post-operation allows doctors to determine if the area is healing properly, has developed an infection, or if scar tissue has formed.
