While representation of resolution through a CTF graph is more rigorous and objective, visualization of the individual phantoms does provide intuitive insight into how resolution affects imaging performance in an image with tissue-relevant scattering and speckle.
Although there is a difference in excitation wavelengths between the two FAF modalities used, this does not affect imaging results as comparison in the brightness of FAF images are not recommended even when using the same imaging modality.
As sgRNA structure could significantly affect imaging quality, a sgRNA scaffold optimized by A-U base pair flip and hairpin extension was used to eliminate protein aggregation and increase bright dot number (Chen et al., 2013).
Chemotherapy treatment induces parenchymal changes that potentially affect imaging of CRLM.
This method minimizes any side perturbations to pollen tubes that could affect imaging settings and conditions (e.g. change of focus, mechanic shock, etc).
Disease can affect imaging biomarkers in numerous ways outside of study hypotheses, such as through the influence of increased head motion, reduced attention or concomitant impairments.
Given that immune mechanisms may play a role in both the early disease process, and in the strategies used to combat it with amyloid-immunomodulatory agents, efforts should be made to better understand how such processes affect imaging biomarkers.
Even though longer exposure times were required, fluorophore bleaching did not affect imaging, possibly due to the reduced bleaching rate at cryogenic temperatures (Schwartz et al. 2007; Gruska et al. 2008).
However, antibodies are rather bulky proteins as compared with the molecular probes typically used for PET imaging [ 17, 18], which make the tumor penetration and clearance from the circulation rather slow, and this, in turn, considerably affects imaging studies.
This problem particularly affects imaging and pathology transfer and may reflect our case mix as it is possible that the Royal Marsden has more tertiary and quaternary referrals than other institutions, which could complicate the retrieval of pathology and imaging.
An issue that potentially affects imaging with any PET tracer is the clinical significance and management of lesion motion due to respiration during PET/CT scanning, which was reviewed by Callahan et al. (Melbourne, Australia).
