Seasonal Allergic Rhinitis Clinical Trial
Official title:
An Investigation to Evaluate the Technique of MRI as an Assessment of the Effect of Anti-allergy Drug Treatment on Internal Nasal and Sinus Mucosal Anatomy Following Intranasal Allergen Challenge in Subjects With Seasonal Allergic Rhinitis.
The purpose of this study is to establish whether MRI scanning is a sensitive measure of the effects of existing drug treatments on nasal dimensions following challenge with intranasal allergen in subjects with hayfever. If successful this technique could be applied to increase confidence for internal decision making and ultimately may be used to assess how effective a new drug treatment is.
