As magnetic resonance we understand a medical procedure that is used to measure brain activity and it serves, among other things, to carry out neurological investigations or detect diseases. Apparently, a procedure as widely used and important as this, could be wrong because a systematic misinterpretation of the data collected so that practically all the MRIs carried out in recent years could be wrong.
This fault has been discovered by the University of Linköping, located in Sweden. To detect and measure the effectiveness of the software in charge of interpreting MRI data, the team of researchers tested hundreds of results in different parts of the world. As a detail, before continuing to tell you that, if the conclusions reached by this team of scientists are right, literally nothing less than about 15 years of scientific research would have to be scrapped and over 40.000 academic papers.
All MRIs done since 1992 could be wrong
The group of experts responsible for this study is blunt with its results as they speak up to 70% false positives to which we would have to add some magnetic resonances that, apparently, would indicate brain activity where there was none. As stated Anders Ecklund, head of this project:
Functional MRIs are 25 years old, and surprisingly its most common statistical methods have not been validated using real data. Here, we have used data from 499 controls to conduct three million group analyzes.
As a detail, tell you that the bugs found in the MRI software was settled in 2015 so it would mean recognizing that, at least, one problem did exist. This software was in charge of interpreting brain activity data since 1992. Undoubtedly, this poses a huge problem for medical and neurological research, since all the studies developed based on the results obtained by this software would be wrong. that today would be called into question.

I have read the first sentence of the article and I immediately stopped reading: «As magnetic resonance we understand a medical procedure that is used to measure brain activity and serves, among other things, to carry out neurological investigations or detect diseases”
First, I don't understand what news like this is doing on a tech blog. Second, if you do not know about the subject, as is evident from the amount of crap you say throughout the article, having bothered to inform yourself a little before. It is very easy to know that what you are talking about is not the Magnetic Resonance, a test that does not detect any brain function, but the "Functional Magnetic Resonance" (fRMN). It would have taken you 5 minutes to find out if you had bothered to look it up.
