How accurate are ct contrast in measuring size of arachnoid cyst / identifying compression of it on the brain?
A doctor has provided 1 answer
Acceptable: The CAT scan can demonstrate the presence and general effect of such a cyst, but the MRI would be preferable due to superior resolution, and precision.
