In clinical diagnostics and longitudinal studies, the reproducibility of MRI assessments is of high importance in order to detect pathological changes, but developments in MRI hard- and software often outrun extended periods of data acquisition and analysis. This could potentially introduce artefactual changes or mask pathological alterations. However, if and how changes of MRI hardware, scanning protocols or preprocessing software affect complex neuroimaging outcomes from, e.

- Longitudinal imaging studies are important for understanding brain development over time, but upgrading MRI scanners can introduce biases and affect reliability.
- A study comparing two MRI scanners found high reliability for grey matter measurements, but significant differences were noted in 67% of brain regions, with variations of about 2-4%.
- It is recommended that researchers address potential biases from scanner upgrades with correction methods before continuing their studies to ensure the accuracy of their findings.
