Imaging and PET — PET/CTimaging [PDF]

Journal de Radiologie, 2008
PET-CT has grown because the lack of anatomic landmarks in PET makes "hardware-fusion" to anatomic cross-sectional data extremely useful. Addition of CT to PET improves specificity, but also sensitivity, and adding PET to CT adds sensitivity and specificity in tumor imaging.

FDG-PET/CT(A) imaging in large vessel vasculitis and polymyalgia rheumatica: joint procedural recommendation of the EANM, SNMMI, and the PET Interest Group (PIG), and endorsed by the ASNC [PDF]

, 2022
Large vessel vasculitis (LVV) is defined as a disease mainly affecting the large arteries, with two major variants. Takayasu arteritis (TA) and giant cell arteritis (GCA).

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.

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 ...

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

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.
