Comparison of propagation-based phase-contrast CT and absorption-based CT for breast imaging using synchrotron radiation

open access: yes, 2020
Propagation-based phase-contrast CT (PB-CT) is a novel imaging technique that visualises variations in both X-ray attenuation and refraction. This study aimed to compare the clinical image quality of breast PB-CT using synchrotron radiation with ...

Geometric Misalignment Calibration and Detector Lag Effect Artifact Correction in a Cone-Beam Flat Panel micro-CT System for Small Animal Imaging [PDF]

open access: yes, 2022
The cone-beam flat panel micro-CT is a high definition imaging system. The CT system is affected by several imperfections and problems, that might lead to serious artifacts that deteriorate the quality of the reconstructed image.

Autism spectrum disorder-specific changes in white matter connectome edge density based on functionally defined nodes

open access: yesFrontiers in Neuroscience, 2023
IntroductionAutism spectrum disorder (ASD) is associated with both functional and microstructural connectome disruptions. We deployed a novel methodology using functionally defined nodes to guide white matter (WM) tractography and identify ASD-related ...

Vectors for Expression and Secretion of FLAG Epitope-Tagged Proteins in Mammalian Cells

open access: yesBioTechniques, 1996
The FLAG peptide, AspTyrLysAspAspAspAspLys, has been used as an epitope tag in a variety of cell types. The modification of the cytomegalovirus (CMV) promoter containing vector, pCMV5, to create two transient expression vectors designed for secretion and

PET and SPECT Imaging of Brain Neoplasia Mimics

open access: yes, 2020
Several non-neoplastic processes, including infection, inflammation, demyelination, vasculitis, autoimmune disease, and post-treatment changes (radiation therapy or chemoradiation) can result in a mass-like, space-occupying lesion on conventional ...
