HRCT Temporal Bone - Axial Scans
What is HRCT Temporal Bone - Axial Scans?
HRCT temporal bone - axial scan is a high resolution computed tomography imaging test that assists in observing specifically the soft tissues and surrounding bones of the temporal region of the brain, I e., the Middle ear. The temporal bone builds the side portion of the skull, which mainly includes the middle and inner ear crossed by brain nerves.
This test is usually done to diagnose chronic and acute swelling or if there is any form of tumor in the middle ear. This test also helps figure out meningocele, a congenital condition where the baby’s spinal cord generally fails to develop properly. HRCT of temporal bone provides an exact overview of the evaluation of temporal bone involvement in different conditions.
Why is HRCT Temporal Bone - Axial Scans done?
- To diagnose chronic and acute swelling, malformation, tumor formation in the middle ear
- To detect cholesteatoma (tumor or abnormal skin growth in the middle ear behind the eardrum)
- To find out meningoencephalocele or meningocele (congenital or birth defect condition where spinal cord of the baby fails to develop)
- To evaluate inner ear swelling which connects ear to the brain resulting in vertigo
