Scientists from Sweden and the UK have cast doubt on the science behind high-resolution magnetic resonance imaging brain scans after they discovered the software interpreting it had a false positive rate of up to 70%. Now, boffins from Sweden and the UK have cast doubt on the quality of the science, because of problems with the statistical software: it produces way too many false positives. Their findings call into question around 40,000 MRI studies and "may have a large impact on the interpretation of neuroimaging results". The researchers found that their software, called NeuroImage, was able to detect changes in blood oxygen levels when people were lying down or standing up.
