Optimisation of CT protocols in PET-CT across different scanner models using different automatic exposure control methods and iterative reconstruction algorithms

EJNMMI Physics, 2021
Background A significant proportion of the radiation dose from a PET-CT examination is dependent on the CT protocol, which should be optimised for clinical purposes.

PET Imaging of Neurofluids. [PDF]

Neuroimaging Clin N Am
Following a brief review of brain neurofluid pathways and the general PET technique, we introduce PET imaging of cerebrospinal fluid and interstitial fluid dynamics. Our summary includes both our published and unpublished observations on the modeling of PET imaging for neurofluid quantification in aging, Alzheimer's disease, and in the presence of ...

Opportunities for PET to deliver clinical benefit in cancer:breast cancer as a paradigm [PDF]

, 2010
The glucose analogue fluorodeoxyglucose (FDG) has demonstrated enhanced uptake in the majority of tumours as a result of increased uptake and fixation by phosphorylation. It is the most widely used radiotracer in positron emission tomography (PET), being

Practical issues and limitations of brain attenuation correction on a simultaneous PET-MR scanner

EJNMMI Physics, 2020
Background Despite the advent of clinical PET-MR imaging for routine use in 2011 and the development of several methods to address the problem of attenuation correction, some challenges remain.

Noninvasive PET Imaging and Tracking of Engineered Human Muscle Precursor Cells for Skeletal Muscle Tissue Engineering [PDF]

, 2016
Transplantation of human muscle precursor cells (hMPCs) is envisioned for the treatment of various muscle diseases. However, a feasible noninvasive tool to monitor cell survival, migration, and integration into the host tissue is still missing. METHODS:

FDG-PET/CT in lymphoma

Indian Journal of Radiology and Imaging, 2013
Lymphomas are a heterogeneous group of diseases that arise from the constituent cells of the immune system or from their precursors. 18F-fludeoxyglucose positron emission tomography/computed tomography ( 18 F-FDG PET/CT) is now the cornerstone of staging

Imaging microglial activation and glucose consumption in a mouse model of Alzheimer's disease. [PDF]

, 2012
In Alzheimer’s disease (AD), persistent microglial activation as sign of chronic neuroinflammation contributes to disease progression. Our study aimed to in vivo visualize and quantify microglial activation in 13- to 15-month-old AD mice using [11C]-(R ...
