The main goal of this imaging modality is to diagnose the site of CSF rhinorrhoea or CSF otorrhoea (CSF leaks). The test can help the healthcare provider determine where the leakage is located. A cerebrospinal fluid leak can happen as a result of trauma like a head injury, brain or spinal surgery, an epidural, and a lumbar puncture. Disclaimer: This test is subject to availability.
