HRCT Temporal Bone - Axial & Coronal with Contrast
Understanding HRCT Temporal Bone - Axial & Coronal with Contrast
What is HRCT Temporal Bone - Axial & Coronal with Contrast?
The HRCT Temporal Bone - Axial & Coronal with Contrast is an advanced imaging test used to get highly detailed images of the temporal bones in the skull, which house the structures of the inner and middle ear. This scan is performed in two planes — axial (horizontal) and coronal (vertical) to provide a complete view of the area.
A contrast dye is used during the scan to enhance the visibility of blood vessels, tissues, and any abnormal changes in or around the temporal bones. This test helps detect ear infections, cholesteatoma, hearing loss, tumors, injuries, bone erosion, or congenital abnormalities affecting the ear structures.
Doctors may recommend this scan if you have symptoms like hearing loss, chronic ear discharge, dizziness, or facial nerve issues. It is also helpful in planning surgeries involving the ear or evaluating post-surgical outcomes.
The procedure is safe, quick, and noninvasive. However, if you have allergies to contrast dye, kidney problems, or are pregnant, inform your doctor beforehand. You may be asked to remain still during the scan for clear and accurate images.
What is HRCT Temporal Bone - Axial & Coronal with Contrast used for?
- To diagnose glomus jugulare tumor (tumor of the temporal bone which affects middle and inner ear)
- To detect injuries to the facial nerve and middle / inner ear parts, facial nerve paralysis and intracerebral hemorrhage (brain injury)
- To find out the extent of hearing loss especially in otosclerosis patients (cancer of bone near the middle ear) and cerebrospinal fluid otorrhea (drainage of fluid from the ear)
