Significance of X-ray Findings in Patients with Respiratory Allergy.

Sinus roentgenography has been thought to be the most sensitive method of detecting sinus infection; however, the significance of abnormal X-rays is uncertain. To determine the usefulness of X-rays in the clinical diagnosis and care of patients with sinus infection, 20 consecutive patients at the St. Joseph's Health Centre allergy clinic were evaluated. Sinus X-ray findings were of clinical assistance in only six cases. Close cooperation between the radiologist and clinician is urged to ensure adequate interpretation of X-ray changes, which can be considered diagnostic if they are compatible with clinical findings.However, clinical findings do not always direct attention to the primary sinus infection. Adequate information is available on the single Water's view for patients with sinus symptoms; other projections in a full radiologic investigation offer no useful information.
