Sure, but in this case, there was a good reason for the additional tests: a high-risk pregnancy. And still, the outcome was stress for nothing. Now, imagine thousands of perfectly healthy people doing full-body scans every week just because they can. This actually carries the risk of jamming real health care, because those perfectly healthy people will undergo additional clinical tests for nothing.
Imagine all the data that gets us towards those scans actually being meaningful. Don't treat them like scans to find problems but scans to learn from, collectively.
As I wrote in replies to other similar comments, this would be the case if this technology was presented as an opportunity for researchers to run more large-scale studies. This isn't however the case, it is instead presented as a shiny toy for fancy spas.
