Discordant findings of different positron emission tomography/CT tracers in a case of glioblastoma
World Journal of Nuclear Medicine, 2021 18F-2-fluoro-2-deoxy-D-glucose ([18F]-FDG) positron emission tomography (PET) CT has proven useful in the evaluation of high-grade glioma and is also useful as a predictor of the degree of malignancy in newly diagnosed brain tumors.

Novel positron emission tomography radiotracers in brain tumor imaging
Indian Journal of Radiology and Imaging, 2011 Although [18F] 2-fluoro-2-deoxy-D-glucose (FDG) is the most widely used radiopharmaceutical the world over, it is not the ideal tracer for brain imaging, owing to its high physiological cortical uptake and lack of specificity.

Evaluation of image quality at the detector’s edge of dedicated breast positron emission tomography
EJNMMI Physics, 2021 Background Using phantoms and clinical studies in prone hanging breast imaging, we assessed the image quality of a commercially available dedicated breast PET (dbPET) at the detector’s edge, where mammary glands near the chest wall are located. These are

PET Imaging of Angiogenesis [PDF]
PET Clinics, 2009 Angiogenesis is a highly-controlled process that is dependent on the intricate balance of both promoting and inhibiting factors, involved in various physiological and pathological processes. A comprehensive understanding of the molecular mechanisms that regulate angiogenesis has resulted in the design of new and more effective therapeutic strategies ...

Deep learning for Dixon MRI-based attenuation correction in PET/MRI of head and neck cancer patients
EJNMMI Physics, 2022 Background Quantitative whole-body PET/MRI relies on accurate patient-specific MRI-based attenuation correction (AC) of PET, which is a non-trivial challenge, especially for the anatomically complex head and neck region.

Multimodality Brain Tumor Imaging: MR Imaging, PET, and PET/MR Imaging [PDF]
Journal of Nuclear Medicine, 2015 Standard MR imaging and CT are routinely used for anatomic diagnosis in brain tumors. Pretherapy planning and posttreatment response assessments rely heavily on gadolinium-enhanced MR imaging. Advanced MR imaging techniques and PET imaging offer physiologic, metabolic, or functional information about tumor biology that goes beyond the diagnostic yield ...
