Can a ct scan pick up an acoustic neuroma?

Often: Both ct and MRI can reveal an acoustic neuroma. Mri is generally more sensitive and may show the tumor earlier.

Not usually: Ct scans use x-rays and are better for imaging bones than soft tissue. A large acoustic neuroma may be seen on ct scan, but MRI with a contrast medium is able to detect small acoustic neuromas that may only be several millimeters in size. Mri uses a magnet for imaging which also has the benefit of no x-ray exposure.
