After entering a search term, your results are displayed within the "Diagnosis Help" tab by default. This returns a three-column response. Diagnoses are displayed in the first column, Expert Differential Diagnoses in the middle, and Imaging Anatomy on the right.
If you wish to view other content besides "Diagnosis Help" click a tab above the search box (Anatomy, RADtools, Procedures.) Your search term will persist after the tab is selected, and that content type will automatically be searched.
