: Magnetic Resonance Imaging (MRI) is a non-invasive imaging modality. However, the effects of MRI on the immune system in the in vivo conditions are yet to be clarified. In this study we explored the effects of routine brain MRI on the protein and mRNA peripheral blood levels of interleukin-6 (IL-6), IL-10, IL-17A and transforming growth factor-beta (TGF-β).

Furthermore, people are also exposed to ionizing radiation from their workplace or the environment. Apart from DNA fragmentation resulting in apoptosis, several additional mechanisms have been proposed to describe how radiation can alter human cell functions.

By reducing image rejection rate (RR), radiation dose to patients can be reduced effectively, yielding increased total cost-effectiveness. The aims of this study were to assess the rate of image rejection at 2 direct digital radiography (DR) departments to find the sources of rejection and to observe how radiology students and radiographers deal with image rejection.

A dose survey was performed in a CT institute by considering patients lateral diameter, weight and body mass index (BMI). The AQD tables for weight and BMI groups and SSDE threshold curves were obtained.
