Effects of Variations in Imaging Parameters on Image Quality of Non Contrast Computed Tomography Scans of Brain: A Cross-sectional Study [PDF]

Journal of Clinical and Diagnostic Research, 2021
Introduction: The radiation dose absorbed during Computed Tomography (CT) investigation of the head, which could be reduced by altering the scan parameters, is of great concern considering the radiosensitive organs around this region.

The Chaperone Protein GRP78 Promotes Survival and Migration of Head and Neck Cancer After Direct Radiation Exposure and Extracellular Vesicle-Transfer

Frontiers in Oncology, 2022
Background and PurposeIncreased levels of the chaperone protein GRP78 have been implicated in poorer outcomes of cancer therapy. We have therefore explored the functional connection between the expression of GRP78 and the development of radioresistance ...

Radiation exposure by medical X-ray applications

GMS German Medical Science, 2022
Background: Radioactive material and ionising radiation play a central role in medical diagnostics and therapy. The benefit of ionising radiation is opposed by the risk of irreparable damage of the human organism.

The impact of high and low dose ionising radiation on the central nervous system

Redox Biology, 2016
Responses of the central nervous system (CNS) to stressors and injuries, such as ionising radiation, are modulated by the concomitant responses of the brains innate immune effector cells, microglia.

Why consider contrast-enhanced ultrasound (ce-US) in children?

Journal of Ultrasonography, 2014
Children are very specific; particularly in terms of radiation sensitivity. They not only have a tenfold higher sensitivity towards radiation, but also a longer expected lifespan where potentially radiation induced tumours may manifest(1–7 ...
