I get the intention, but you made an assumption that the person you replied to didn’t spend 30 seconds find some more supporting evidence before they made their post. But as far as trust goes, Hacker News has historically been a fairly high trust community. LLMs have the potential to change this dynamic, but I don’t think encouraging people to assume that every post is an LLM is helpful. I don’t think a community wit…

Maybe it's the time I've joined at, but I've noticed a lot of bot users and stories which has soured my view a bit. Thanks for engaging in good faith and giving me context, I'll try to have more grace in the future

It is.

Exposing asymptomatic potential issues leads to medical care that often does not meet out standards for medical tradeoffs. Chemo is nasty, even the most minor surgery has risks. We endure the risks because we are addressing either major health issues or other dire uncertainties. Using our heavy duty treatments for issues without any symptoms at all would, normally, cause the patient suffering in excess of what would…

If you seriously think this is a realistic scenario, you should call your doctor and tell him you've decided you have cancer and would like to order chemotherapy. See what he says. Nobody is deciding for themselves to do chemo because they think something looks funny on a scan. All the scan gives them is a reason to talk to their doctor, who will do all the usual due diligence before deciding on treatment, if any. An…

Maybe it would end up fine “in the long run” but you cannot ignore the significant issues arising at the beginning (and at each release of a more performant tool): what do you do if you find something that “shouldn't be there".

With enough data, it might change our idea of what shouldn’t be there. Like an appendix. But personalized!

That's exactly what I'm talking about when I say “in the long run” the problem comes in the meantime (and no, I don't think people in the present should endure bad things because it's going to make the future better).

> Many people mistakenly believe that early diagnosis is the final boss in medicine,

True. My more nuanced take on it: For most chronic conditions (including cancer) diagnostics have improved but resolution has not. The PR machine of course hypes things to make it seem like we have more cures today that in the past. What is have is more diagnostics and more procedures.

I don't understand how people can hate on this. It's probably the most novel & ambitious consumer health device ever? Plus they're doing it fully bootstrapped. Let them cook!

How old are you? I've been conned all my life by tech companies selling us "deliverance from work", "permanent Mars bases", "asteroid mining", "AR/VR everywhere, for everyone, all the time", "crypto will replace money", "3d TVs are the new hot shit", "self driving cars for everyone in 2 years tops" I don't understand how people are so gullible? How do they keep falling for it?

As they say there is a new sucker born every minute.

First, many regular people are “stupid” in the sense that they do get anxious about things that ar slow probability and are not anxious about things that are high probability. If you are a billionaire you also have a doctor with the time and expertise to properly evaluate the evidence in a Bayesian framework, and you have time to talk to them and understand and implications. That isn’t scalable. Also, it’s quite like…

Ok but now the argument shifted from "More MRI = bad" to "More MRI = okay as long as doctors do a good job and have enough time". I agree with that. My point was just that it's possible to get to a point where everyone having yearly MRIs is doable because the issue isn't with more information in itself, it's with doctors not having enough time for the patient.

But now your argument also depends on no opportunity costs for doing unneeded mri, or infinite medical resources.

As I said … we really don’t known how much harm billionaires are suffering (sob) and there are much simpler explanations for their longevity.

> The brain is encased in bone, so you might get some penetration but it will be very limited. Radiologist as well. Remember this is full wave inversion not pulsed wave B mode. You can get much more useful information from both high low frequency and capture transmitted waves. There is promise with this and we use it for example with MRgFUS. With advanced computational models or patient specific CT/ZTE MR aberration…

What's the use of FWI for a moving target - which someone floating in a spa most definitely will be?

This is a fever dream, not a practical diagnostic technology.

I can imagine it being useful if you happened to own an imaging product and wanted to train a model on human body shapes and sizes.

But dunking people in a golden spa - why golden? why not pink or teal? - and waving a ring of US over them, at distances which make high resolution impractical, to tell them their medical fortunes is... eccentric.

I'm being scathing because there's no solid science behind this, and if there had been solid science MJ would have published it in a paper.

This is pure marketing. And if you're going to do that, you should at least include some dolphin petting.

> ultrasound is not CT They're using "CT" in its literal sense: tomography*, using computers. In this case, ultrasound is the penetrating wave rather than x-ray. It is of course a very different thing than what the medical world knows as "CT" today. * https://en.wikipedia.org/wiki/Tomography

The problem is the other way around. That we somehow accepted that X-Rays/Röntgen is the only way to do CT.

What warming feeling? An MRI shouldn't really make you feel warm unless they're pushing IV contrast.

My understanding was that your body was absorbing some amount of whatever electromagnetic stuff passes through you for the image. And the techs have told me it’s nothing to worry about.

MRIs are so much cooler than that. https://www.radcommons.org/residents/files/physics/MRI_Made_... is a good read.

That sounded like a zinger in your head, eh? It's okay bud, spending every waking minute posting snark on HN must be tiring.
