Diagnostic Accuracy of Positron Emission Tomography/Computed Tomography of the Head, Neck, and Chest for Giant Cell Arteritis: A Prospective, Double‐Blind, Cross‐Sectional Study

Objective Positron emission tomography/computed tomography ( PET / CT ) has not been well studied as a first‐line test for giant cell arteritis ( GCA ), due, in part, to historical limitations in visualizing the cranial arteries. The Giant Cell Arteritis and PET Scan ( GAPS ) study was therefore carried out to assess the accuracy of a newer generation PET / CT of the head, neck, and chest for determining a diagnosis of GCA . Methods In the GAPS...
