Outcome Measures

Primary Outcomes (1)

  • To Measure the Distribution of Nasal Sprays and Drops.

    CT scan scored for distribution contrast delivered by nasal spray or drops within subsets in the nasal cavity. The sinonasal cavity was divided into twenty-one subsites on each side of the nasal cavity. The interpreters scored for the presence (1) or absence (0) of contrast from the nasal spray or nasal drops within each subsite. Left and right sides were interpreted separately for a possible total score of 0-42 for each CT scan.

    2 months

Study Arms (2)

Nasal spray

EXPERIMENTAL

This arm of the study will contain subjects who will spray 2-4 sprays of a nasal contrast solution in their nares. Following administration of the spray, the subjects will then have a Xoran mini-CAT scan of their sinuses.

Radiation: Sinus CT ScanDrug: Omnipaque 240 Contrast Solution

Nasal drop

EXPERIMENTAL

This arm will contain subjects who will place two drops of a nasal contrast solution in each nose. Following administration of the nasal contrast, the subjects will then have a Xoran miniCAT scan of their sinuses.

Radiation: Sinus CT ScanDrug: Omnipaque 240 mg I/mL

Interventions

Nasal dropNasal spray

Subjects will spray 2-4 drops of half-strength Omnipaque 240 mgI/mL into each nare. Each spray is approximately 0.1 ml.

Also known as: contrast enhancement
Nasal spray

Subjects will place two drops of half-strength Omnipaque 240 mg I/mL intranasally to each nose. Each drop is approximately 1 ml.
