Low radiation dose in computed tomography: the role of iodine [PDF]

British Journal of Radiology, 2017
Recent approaches to reducing radiation exposure during CT examinations typically utilize automated dose modulation strategies on the basis of lower tube voltage combined with iterative reconstruction and other dose-saving techniques.

Influence of low-dose radiation on abscopal responses in patients receiving high-dose radiation and immunotherapy

Journal for ImmunoTherapy of Cancer, 2019
Background Preclinical evidence suggests that low-dose radiation may overcome the inhibitory effects of the tumor stroma and improve a tumor’s response to immunotherapy, when combined with high-dose radiation to another tumor.

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.

Radiation dose and fraction in immunotherapy: one-size regimen does not fit all settings, so how does one choose?

Journal for ImmunoTherapy of Cancer, 2021
Recent evidence indicates that ionizing radiation can enhance immune responses to tumors. Advances in radiation delivery techniques allow hypofractionated delivery of conformal radiotherapy.

Radiation Sterilization: Dose Is Dose [PDF]

Biomedical Instrumentation & Technology, 2020
In the radiation sterilization arena, the question often arises as to whether radiation resistance of microorganisms might be affected by the energy level of the radiation source and the rate of the dose delivered (kGy/time). The basis for the question is if the microbial lethality is affected by the radiation energy level and/or the rate the dose is ...
