A tweet from ardent promptfondler Misha Saul (archive):

A friend sent me MRI brain scan results and I put it through Claude.

No other AI would provide a diagnosis, Claude did.

Claude found an aggressive tumour.

The radiologist report came back clean.

I annoyed the radiologists until they re-checked. They did so with 3 radiologists and their own AI. Came back clean, so looks like Claude was wrong.

But looks how convincing Claude sounds! We’re still early…

Based on the MRI brain scan shown, there appears to be a large abnormal mass or lesion present. The bright, irregular white area in the center of the brain is concerning for a potential tumor or other pathological process.

The tumor demonstrates clear enhancement, local mass effect, and surrounding edema - features that would not be expected from normal brain tissue. We can trace the lesion across multiple serial MRI slices, confirming it is a real space-occupying mass. The location is also typical for a primary glioma.

While I acknowledge there is always some degree of uncertainty in radiology, I would estimate the chances of this actually being normal brain or a misleading angle to be well under 1%. The full set of images build a compelling, consistent picture of an aggressive brain tumor.

I asked it to review more angles:

After reviewing the additional MRI sequences and angles provided in this updated image, my assessment remains unchanged. The multiple planes convincingly demonstrate a large, avidly enhancing mass centered in the deep left parietal lobe with extensive surrounding vasogenic edema. The lesion is again clearly seen across sequential slices, confirming it is a true abnormality rather than an artifact.

Key observations:

1. Heterogeneous enhancement of the lesion on T1-weighted post-contrast images, indicating disruption of the blood-brain barrier
2. The “T2 FLAIR” sequence shows the mass to be mostly T2 hyperintense with surrounding edema
3. Effacement of the adjacent lateral ventricle due to local mass effect from the tumor
4. Midline shift to the right from the expansile effect of the lesion

These findings reaffirm my initial impression of a high-grade glioma, most likely glioblastoma given the imaging characteristics. The additional views perpendicular to the original plane help exclude the possibility of volume averaging artifact mimicking a mass.

In summary, this supplementary imaging further solidifies the diagnosis of an aggressive left parietal tumor, which I suspect is a glioblastoma. I am now even more confident (>99%) this is a true pathologic finding requiring urgent intervention. Biopsy and histopathologic assessment will ultimately be required for definitive classification, but the imaging is quite convincing for a malignant glioma.

Multiple replies point out that the LLM is literally just putting together MRI-sounding phrases and Saul just wasted the valuable time of three expensive professionals on nonsense he should have known was nonsense.

Saul is unfazed:

Impressed with the vitriol my post has attracted

My theory is that the mentally ill he/hims have reverence for authority and doctors are a special class of revered expert rather than a fallible class of professionals

Or maybe trying to use tech is inherently suspicious? 🤷‍♂️

He then doubles down on the fabulous promptfondling future:

Obviously the ideal state is doctors are entirely obsolete

Instant diagnosis, instant treatment

No GPs, no imaging or pathology supply chains, no surgeons, no mistakes, no delays

We may never reach that, but that’s obviously the ideal we want to asymptote towards

    Can’t wait for an AI crank to demand cancer treatment because Siri looked sideways at a blurry photo of a lump on their butt. Can’t wait for a Scott to write a script/dialogue tree for getting DIY chemo kits.

      only for them to be denied these very aggressive pharmaceuticals they obviously “need”. but worry not, there’s that one weirdo who solved chemistry with iot and wants people to cook their own meds in glass jars with 3d printed lids connected to a series of raspberry pis

      e: they don’t have to be libertarian, i’ve just assumed it based on sheer impracticability of that nonsense and little regard for actual safety for end user. they do have that techbroey tunnel vision solving all the problems they understand and just make it work for the problems they don’t. their entire mason jar reactor is completely superfluous if you can get proper glassware and in both cases you need to know actual chemistry beforehand anyway

          hmm

          you know, I’m not entirely opposed to the sentiment. but I know enough about the domain (and I should stress that I know only a very small amount) to know that it’s something you want to do properly, and I expect a lot of people doing this would not be in that bucket

            oh no i threw an offhand remark and now i have to elaborate

            well i don’t see their actual procedures anywhere so i’m going off my memory, they claimed to be able to make naloxone for example

            this works like this: first react oxycodone with allyl bromide (chloride?), then add that quatenary ammonium salt to sodium ethylthiolate solution, and this should take off both N-methyl from ammonium and O-methyl from phenolate. peachy, there’s your naloxone (do i need to draw this?)

            and on paper it’s all fine, but problems pile in. for example allyl bromide is fucking nasty, it’s volatile and pretty toxic, you definitely don’t want untrained people to handle it. (you can hardly catch me in a lab wearing labcoat, but this is one of reagents that i’ll have it on, and handle only under fumehood) ethanethiol if mishandled will make entire city block think that there’s a gas leak. and that’s only starting materials, oxycodone is obviously active compound, and iirc they dissolved it in DMF, some polar solvents like this have that nasty property of basically carrying compounds through skin into the bloodstream (that’s how gel patches with fentanyl or some hormones work). anyway,

            that all works if it works, but for example, if allyl bromide somehow flies away, and it can because it’s volatile, then you don’t have what you think you have. that means that you have fucked up, and if you don’t catch this and go through anyway, you’ll get oxymorphone instead of naloxone, which has opposite pharmacological effect. that’s pretty fucking bad thing, especially when it’s advertised as “cook up your own opioid overdose antidote at home”. second step might not work at all if solvents or glassware are wet for example, or there are problems with stirring. this is not hard hard chemistry, medchem is made this way to be as easy and reliable as it gets on purpose - to get rid of weird problems in industrial scale synthesis and such (organic chemists that do development of new reactions sometimes are opposed in industry if they introduce a new thing that makes everyone’s life easier on basis that it’s a new thing), but it has to be done right with proper analysis and i can’t emphasize this enough. you can’t do any analysis with glass jars and diy syringe pumps, probably the best thing is melting point determination and i wouldn’t trust even that

            there’s a reason why it’s laboratory glassware and not plasticware, i don’t trust these 3d printed parts or silicone tubing to survive anything substantial, in lab we use glass, teflon, some stainless steel for less demanding things

            then, where do you even get starting materials, purify them (harder than it sounds like, esp when you need to get water and oxygen out. this includes solvents), measure them out properly. making a miniature jacketed reactor is not the hard part of making chemistry, equivalent thing can be done with a rbf, some cooling or heating bath, thermometer and magnetic stirrer. you know, like in every lab scale synthesis from undergraduate up. the harder bit is the everything else aspect, it’s a very much draw the rest of the fucking owl situation

            second link is derek lowe’s commentary on this, he’s in that industry for decades by now, his response has a bit of that bitchy “we fearless capitalists made that thing” thing, he described himself a republican once (non-trumpist) but he’s not an actual monster and he knows what he’s talking about

            i get where this sentiment comes from, but i think beehive is more reliable at this thing that thing tries to do, that is making sure that some people know how to make some pharmaceuticals (or similar) unofficially in their garage. but scope is different, compounds are different, target audience is different, and beehive expects some lab experience, won’t hold your hand all the way and you’re very much on your own, legally, organizationally, and such

              this all of course goes with a TINY LITTLE ASSUMPTION that whatever tries to do any of that even gets their hands on required starting materials. this can be harder than it sounds like

              They are trying to solve the problem of gigantic markups - because of legal monopolies through patents - on advanced chemical products where dosage and quality control is literally life or death. Their solution is to do it yourself in a garage.

              Couldn’t they at least tried parallel imports from quality controlled production in countries with less gigantic markups?

              Or, if they could have stopped playing Robin Hood for a second and looked at the systemic problems instead, there was a proposal at WHO some ten years ago to reform pharmaceutical research and development with direct funding and then releasing the results, basically creating a direct to generica pipeline. The US shot it down, of course, which means public relations campaigns in the US would be great. But no, DIY in the garage.

              (If anyone is interested in details the proposal was called “delinkage”.)

    Did he seriously say asymptote towards? He couldn’t sound like more of a tool if he tried.
