Differences in gross tumor volumes for pancreatic cancer: a comparison of ungated positron emission tomography and contrast-enhanced four-dimensional computed tomography

ConclusionGTV-PET based on 3D-PET images was smaller than GTV-4DCT for pancreatic cancer. When we refer to 3D-PET images without CE-4DCT images, we need to pay attention to the above-mentioned finding to contour the GTV.
