Evaluating metallic artefact of biodegradable magnesium-based implants in magnetic resonance imaging.

Magnesium (Mg) implants have shown to cause image artefacts or distortions in magnetic resonance imaging (MRI). Yet, there is a lack of information on how the degradation of Mg-based implants influences the image quality of MRI examinations. In this study, Mg-based implants are analysed and in the clinical setting for various magnetic field strengths with the aim to quantify metallic artefact behaviour.

Extracting data from graphs: A case-study on animal research with implications for meta-analyses.

Systematic reviews with meta-analyses are powerful tools that can answer research questions based on data from published studies. Ideally, all relevant data is directly available in the text or tables, but often it is only presented in graphs. In those cases, the data can be extracted from graphs, but this potentially introduces errors.
