Applications of Small Animal Imaging with PET, PET/CT, and PET/MR Imaging

PET Clinics, 2008
Small animal techniques of PET, MR imaging, and CT are most frequently applied in preclinical oncology research, but cardiovascular and neurologic research protocols can also take advantage of these innovative approaches. PET is used to provide functional information about disease activity.

PET Imaging in Neuroinflammation

2014
The presence of microglial activation in the brain provides a marker of disease activity. The function of activated microglia can be both detrimental and beneficial depending on the phenotype. Microglia with the M1 phenotype release cytokines, which may drive disease progression, while M2 microglia generate restorative growth factors, help clear ...

PET/MR Imaging in Cardiovascular Imaging

PET Clinics, 2019
With the emergence of PET/MR imaging there have been some strides in replicating the cardiovascular imaging success of other hybrid imaging modalities such as PET/computed tomography (CT) and single-photon emission computed tomography/CT. Because of the combined molecular imaging capabilities of PET and high-spatial and high-contrast resolution of MR ...

Fundamentals of PET and PET/CT imaging

Annals of the New York Academy of Sciences, 2011
In this review, the fundamental principles of fluorodeoxyglucose (FDG) positron emission tomography (PET) and FDG PET/computed tomography (CT) imaging have been described. The basic physics of PET instrumentation, radiotracer chemistry, and the artifacts, as well as normal physiological or benign pathological variants, have been described and presented

Molecular Imaging by PET

2003
Positron emission tomography (PET) allows quantitative measurements of regional physiological and biochemical processes to be made in vivo in humans. PET determines the three-dimensional distribution of activity in the organ being studied after the subject is administered a tracer labeled with a positron emitting radionuclide.

Diagnostic Imaging: PET/CT(PET)

2020
PET (Positron-Emission Tomography) has a unique feature that is visualized “metabolic activities” of cell, or tissue. Malignant tumors including esophageal cancers usually show hypermetabolism of glucose to be depicted clearly by using FDG-PET.

FDG-PET and amyloid-PET imaging

Current Opinion in Neurology, 2014
The availability of PET neuroimaging tools for the in-vivo assessment of metabolic dysfunction and amyloid burden in Alzheimer's disease has opened important methodological and practical issues in the diagnostic design and the conduct of new clinical trials.
