Apparently there is a lot more information gathered in brain scans than what I thought. I did not realize how much data is collected and can be analyzed.
They can reveal what diseases you have, what happened in your past, and maybe even what might happen in the future.
Although many people are aware of how much data is in DNA fewer people know about how much information is in brain scans.
fMRI analysis techniques are getting so powerful that the networks can be used like a fingerprint. fMRI networks may be even richer in information than PET–but also more problematic. The networks (sometimes called “functional connectivity” patterns) have been used to predict intelligence. They have been used to predict the emergence of schizophrenia or future illicit drug use by at-risk adolescents. Functional connectivity is being used to predict which adult drug abusers will complete a treatment program and who is likely to engage in antisocial behavior. Some predictions are already 80 to 90 percent accurate or better. Driven by AI and ever-faster computers, the predictive ability of the scans will improve.
Too much info in this article to paste or paraphrase in here but eye-opening how much info can be gathered.
This particularly caught my eye though:
Could a court order someone to undergo fMRI or PET? Could a prosecutor subpoena a brain scan that a suspect consented to in the past as a research volunteer?
The principle of “autonomy” establishes the right of volunteers to control how their brain scans will be used – scientifically or otherwise. The public who funds, and the volunteers who participate in research studies must have confidence that brain scanning is being conducted ethically and that the far-reaching personal information being generated is being used only as intended.
Since I volunteer a lot for medical research MRI's of my brain are out there in some studies. Not sure I want them to be available to just anyone.
