Diffusion-weighted MRI and 18F-FDG PET/CT in assessing the response to neoadjuvant chemoradiotherapy in locally advanced esophageal squamous cell carcinoma

摘要

Images from a patient with a cT3N1M0 lower thoracic esophageal squamous cell carcinoma with pathological complete response to neoadjuvant chemoradiotherapy. A, B: PET/CT images before nCRT; C, D: PET/CT images five weeks after nCRT; E, G, I: T2 weighted MRI images, F, H, J: DW-MRI images (b value = 800 s/mm2); E, F: before nCRT; G, H: 13 fractions during nCRT; I, J: five weeks after nCRT. PET/CT positron emission tomography/computed tomography; DW-MRI diffusion-weighted magnetic resonance imaging
