Planning

Settings

  • A low-dose CT without contrast is generally sufficient in suspected acute sinusitis.
  • Normal radiation dose is indicated in suspected chronic sinusitis.
  • Imaging without and with IV contrast is indicated in a suspected facio-maxillary abscess.

Evaluation

Right-sided chronic sinusitis, with sclerotic thickened wall.
  • Mucus content in paranasal sinuses.
  • Any sclerotic thickening of the walls of the sinuses, indicating chronic sinusitis.
