Imaging and PET — PET/CTimaging [PDF]

open access: yesJournal 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.

Multimodality Brain Tumor Imaging: MR Imaging, PET, and PET/MR Imaging [PDF]

open access: yesJournal 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 ...

Discordant findings of different positron emission tomography/CT tracers in a case of glioblastoma

open access: yesWorld 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.

Impact of tumor-specific targeting on the biodistribution and efficacy of siRNA nanoparticles measured by multimodality in vivo imaging [PDF]

open access: yes, 2007
Targeted delivery represents a promising approach for the development of safer and more effective therapeutics for oncology applications. Although macromolecules accumulate nonspecifically in tumors through the enhanced permeability and retention (EPR ...

Novel positron emission tomography radiotracers in brain tumor imaging

open access: yesIndian 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

open access: yesEJNMMI 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

A review of PET attenuation correction methods for PET-MR

open access: yesEJNMMI Physics, 2023
Despite being thirteen years since the installation of the first PET-MR system, the scanners constitute a very small proportion of the total hybrid PET systems installed.

Melanocortin 1 receptor targeted imaging of melanoma with gold nanocages and positron emission tomography [PDF]

open access: yes, 2018
Purpose: Melanoma is a lethal skin cancer with unmet clinical needs for targeted imaging and therapy. Nanoscale materials conjugated with targeting components have shown great potential to improve tumor delivery efficiency while minimizing undesirable ...

Deep learning for Dixon MRI-based attenuation correction in PET/MRI of head and neck cancer patients

open access: yesEJNMMI 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.
