Fig. 1From: Qualitative visual trichotomous assessment improves the value of fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography in predicting the prognosis of diffuse large B-cell lymphomaFluorine-18 fluorodeoxyglucose (18 F-FDG) positron emission tomography/computed tomography (PET/CT) scans of diffuse large B-cell lymphoma (DLBCL) with a score of 4. (a), baseline PET/CT; (b), final PET/CT (F-PET/CT). A 26 year-old woman with bulky mediastinal uptake on baseline PET/CT, which was interpreted as indeterminate on F-PET/CT using the qualitative visual trichotomous assessment (QVTA) criteria; the residual foci (red arrow) were diagnosed and scored as 4. However, the Deauville criteria interpreted the scan as positive. The patient was alive and in complete remission 41 months after treatment initiationBack to article page
