Advanced Imaging for Early Prostate Cancer Staging 

Don’t perform PET, CT, and radionuclide bone scans in the staging of early prostate cancer at low risk for metastasis.

Imaging for Low Back Pain

Imaging for Uncomplicated Headaches 

Don’t do imaging for uncomplicated headache.


CT for Minor Pediatric Head Injury 

CT scans are not necessary in the immediate evaluation of minor head injuries; clinical observation / Pediatric Emergency Care Applied Research Network criteria should be used to determine whether imaging is indicated.


CT for Adult Minor Head Trauma 

Avoid computer tomography (CT) scans of the head in emergency department patients with minor head injury who are at low risk based on validated decision rules.


Advanced Imaging for Pediatric Febrile Seizures 

Neuroimaging (CT, MRI) is not necessary in a child with simple febrile seizure
