SmartAnswer by DigiNepal SI

Mastoid X-ray is a diagnostic imaging procedure that uses X-rays to examine the mastoid air cells, which are small spaces behind the ear. It is typically used to diagnose chronic ear infections. Preparation involves removing metal and jewelry from the area and informing staff if you are pregnant. The radiation exposure is low, with an effective dose ranging from 0.02 to 0.1 mSv, which is similar to the natural background radiation you might experience over a few days. The procedure usually takes a few minutes and requires interpretation by a qualified health worker.
