Time-course of effects of external beam radiation on [18F]FDG uptake in healthy tissue and bone marrow. [PDF]

, 2008
The utility of PET for monitoring responses to radiation therapy have been complicated by metabolically active processes in surrounding normal tissues.

Numerical Solution of the Tomography Problem in Domains with Obstacles [PDF]

arXiv, 2011
We study numerical methods of tomography in domains with a reflecting obstacle. It will be shown that tomography with sets containing both broken rays, i.e. rays reflecting at the obstacle, as well as unbroken rays, has a smaller error between the original and reconstructed image compared to classical tomography methods.

Distinct CTC Specific RNA Profile Enables NSCLC Early Detection and Dynamic Monitoring of Advanced NSCLC

Advanced Science, EarlyView.
A quantitative CTC RNA assay is developed by incorporating multi‐antibody‐based CTC isolation and specific mRNA quantification using RT‐ddPCR. The NSCLC CTC ScoreD demonstrates high accuracy for early‐stage NSCLC detection, significantly outperforming serum CEA. NSCLC CTC ScoreM exhibits a more accurate early‐warning of responses to different therapies

Synthesis and application of (18F) fluorodeoxyglucose in oncology diagnosis

Journal of Education, Health and Sport, 2017
[18F] Fluorodeoxyglucose ([18F] FDG) is the most commonly used radiopharmaceutical in clinical positron emission tomography (PET) in oncology. Cancer cells create their own specific microenvironment to survive and grow.

Jordan Form and Quantum Tomography [PDF]

arXiv, 2015
In this brief article we indicate a connection between Jordan normal form of a square matrix and the stroboscopic approach to quantum tomography. We show that the index of cyclicy of a generator of evolution, which receives much attention in the stroboscopic tomography, can be defined and computed by referring to the Jordan decomposition of a square ...

The State of High‐Resolution Imaging of the Human Inner Ear: A Look Into the Black Box

Advanced Science, EarlyView.
High‐resolution imaging of the cochlea is challenged by numerous unique aspects of this organ, where sensorineural cells, crucial for hearing, are too small for conventional modalities like magnetic resonance imaging and computed tomography. This article reviews current imaging techniques, emerging technologies, and innovations aimed at improving ...

Existing Pittsburgh Compound-B positron emission tomography thresholds are too high: statistical and pathological evaluation.

Brain : a journal of neurology, 2015
Amyloid-β, a hallmark of Alzheimer's disease, begins accumulating up to two decades before the onset of dementia, and can be detected in vivo applying amyloid-β positron emission tomography tracers such as carbon-11-labelled Pittsburgh compound-B.

Prognostic value of subventricular zone involvement in relation to tumor volumes defined by fused MRI and O-(2-[18F]fluoroethyl)-L-tyrosine (FET) PET imaging in glioblastoma multiforme

Radiation Oncology, 2019
Background Subventricular zone (SVZ) involvement is associated with a dismal prognosis in patients with glioblastoma multiforme (GBM). Dual-time point (dtp) O-(2-[18F]fluoroethyl)-L-tyrosine (FET) PET/CT (PET) may be a time- and cost-effective ...
