Neuroradiology is a subspecialty of CHI St. Luke’s Health - The Woodlands Hospital Diagnostic Imaging department that is devoted to the imaging of the central nervous system (the brain and spine) and the head and neck.  The most commonly performed CT Scan procedures are  brain, sinuses, orbits, and temporal bones; soft tissue neck, and the entire spine. The radiologists, who interpret the exams are board-certified and specialty trained in Neuroradiology.

CT scanning is typically performed to:

  • Detect bleeding, brain injury and skull fractures in patients with head injuries.
  • Detect bleeding caused by a ruptured or leaking aneurysm in a patient with a sudden severe headache.
  • Detect a blood clot or bleeding within the brain shortly after a patient exhibits symptoms of a stroke.
  • Detect a stroke, especially with a new technique called Perfusion CT.
  • Detect brain tumors.
  • Detect enlarged brain cavities (ventricles) in patients with hydrocephalus.
  • Detect diseases or malformations of the skull.
  • Evaluate the extent of bone and soft tissue damage in patients with facial   trauma, and planning surgical reconstruction.
  • Diagnose diseases of the temporal bone on the side of the skull, which may be causing hearing problems.
  • Determine whether inflammation or other changes are present in the paranasal sinuses.
  • Assess aneurysms or arteriovenous malformations through a technique called CT angiography.

Your physician will give you detailed instructions on how to prepare for your CT Scan.  Please inform your physician of any medications you are taking as well as any allergies you may have, especially an allergy to iodine.  Also inform your physician regarding a recent illness or other medical conditions.

Women should inform their physician if they are pregnant, or if there is any possibility they may be pregnant. 

Radiation dose: Special care is taken during X-Ray examinations to use of the lowest radiation dose possible while producing the best images for evaluation.
