Keywords: Appendicitis, Computed tomography, Scan range, Radiation dose Background Appendicitis is a common cause of abdominal pain and affects patients of all age groups [1]. Despite the typical clinical presentation, imaging is crucial to rule out differ-ential diagnoses, make the correct diagnosis and there-fore prevent unnecessary surgery.

Impact of Positron Emission Tomography/Computed Tomography

BACKGROUND: In head and neck cancer (HNC), 3-month post-treatment positron emission tomography (PET)/computed tomogra-phy (CT) reliably identifies persistent/recurrent disease. However, further PET/CT surveillance has unclear benefit. The impact of post-treatment PET/CT surveillance on outcomes is assessed at 12 and 24 months.
