Advances in diagnostic imaging techniques (e.g., computed tomographic [CT] scan and magnetic resonance imaging [MRI]) have enhanced the understanding and management of sinusitis. Image-guided navigation systems used in endoscopic sinus surgery have shown a reduction in the need for revision surgeries. Bone window views provide excellent resolution and a good definition of the complete osteomeatal complex and other anatomic details that play a role in sinusitis.2 The coronal view also correlates best with findings from sinus surgery. Doctors do not generally recommend CT scanning for pregnant women unless medically necessary because of potential risk to the unborn baby.
