In their article, Rusthoven and colleagueshighlight the utility ofcombined positron-emission tomography/computed tomography(PET-CT) imaging for diagnosing primaryand recurrent head and neckcarcinoma, and for defining tumor targetvolumes for radiotherapy treatmentplanning in the head and neck. PEToffers noninvasive measures of tumorbiology yet suffers from limited spatialresolution; the physiologic informationobtained with PET is complementaryto the high-resolution structural informationobtained with CT or magneticresonance imaging (MRI).
