Sinus CT scans or antibiotics

Acute rhinosinusitis, or a sinus infection, is a common condition in which the areas surrounding nasal passages become inflamed. It's generally diagnosed clinically and does not require a sinus CT scan or other imaging, according to the American Academy of Allergy, Asthma and Immunology. Antibiotics are also not recommended for patients with mild sinusitis, especially not before seven days of experiencing symptoms.

Brain imaging after fainting or for an uncomplicated headache 

Brain imaging is a useful way to pinpoint some mysterious problems - but it's not always the best option for uncomplicated headaches or after fainting. Those with headaches but without any risk factors for structural disease are unlikely to find successful treatment through brain imaging.

After fainting, some patients are told to undergo brain imaging as well - but according to the American College of Physicians, if the patient has no evidence of seizure or other neurological symptoms, brain scans are unlikely to help.
