18-FDG-PET scanning is an important imaging modality in the staging and monitoring of many malignancies, including lymphoma. Some tumors, however, do not have the high glucose uptake needed for 18-FDG uptake, and are therefore not well imaged by PET. In order to assess whether the histologic subtype of a lymphoma is related to its visibility by PET imaging, this retrospective analysis of PET scans was performed at the University of Pennsylvania. The author's assessed PET positivity of newly diagnosed and untreated relapsed lymphoma by WHO classification of the tumors.
Materials and Methods
Of >600 PET scans performed on patients with lymphoma, 155 cases had
pathologic data available for correlation.
Jul 1, 2014 - Use of multiparametric 18fluorodeoxyglucose positron emission tomography magnetic resonance imaging (MP 18FDG PET-MRI) using dynamic contrast-enhanced MRI, diffusion-weighted imaging, three-dimensional proton MR spectroscopic imaging, and 18FDG-PET can improve differentiation of benign and malignant breast tumors, according to a study published online June 24 in Clinical Cancer Research.
