Man Saves Wife's Sight By 3D Printing Her Tumor 164

An anonymous reader writes: Michael Balzer, a former software engineer and Air Force technical instructor, found himself unsatisfied with a doctor's diagnosis of a small tumor behind his wife's left eye. Balzer had recently become proficient at creating 3D models, so he asked the doctor for the raw medical imaging data and took a look himself. In addition to correcting a later misdiagnosis, Balzer 3D printed models of his wife's cranium and helped neurosurgeons plan a procedure to remove the tumor, instead of waiting to see how it developed, like previous doctors had recommended. During the procedure, surgeons found the tumor was beginning to entangle her optic nerve, and even a six-month wait would have had dire consequences for her eyesight.

Medical researchers like Dr. Michael Patton believe this sort of prototyping will become "the new normal" in a very short time. He says, "What you can now do through 3D printing is like what you're able to do in the software world: Rapid iteration, fail fast, get something to market quickly. You can print the prototypes, and then you can print out model organs on which to test the products. You can potentially obviate the need for some animal studies, and you can do this proof of concept before extensive patient trials are conducted.

    Most medical imaging equipment will dump out a DICOM file, which, IIRC, can be translated into the more typical 3D formats. So pretty much everybody that gets a CT or MRI could get the data. Then you just have to set up the printer.

    I could see this as a growth industry for hospitals (hey, we need the money) - instead of getting some miserable little CD with your image, you get a plastic skeleton (or plastic squishy part). Coffee table discussion item or new D&D figurine?

        Not quite... Since it's not actually PART of the imager itself, it needn't be FDA approved. However, if it were .... yes. We had a generic hard drive fail on our CT. Just a typicall 400 GB SATA drive. We had literally dozens of them hanging around but we couldn't use it because they were not special FDA approved generic SATA hard drives. No special firmware needed - the console for the CT runs a GE version of Linux (you can see this as it boots). All the drive did was hold the images temporarily. It couldn't kill the patient unless you threw it at them. But we had to shut the machine down for 48 hours until they could FexEx a drive to Anchorage and commercial jet it in.

        So, we'd probably only charge $2000 for the gizmo (the specialist time would be included since they are not a doctor - you can only add special charges for doctors).

          If physicians are using the 3D printed model to plan their surgery, how could it not require approval? If the printer sometimes misprints by a mm that could make the difference between a successful surgery and accidentally severing an important nerve, so it seems that the manufacturer would need to test and certify a printer to ensure that it creates accurate models, otherwise they have no assurance that whatever cheap 3D printer the hospital buys at Walmart prints accurately with their software.

          The FDA regulates computer monitors used to view medical imaging, so I don't see why they wouldn't regulate 3D printers used to "print" that same imaging data.

A couple of practice runs on a tactile 3D model of the real thing would make the job a hell of a lot easier when it comes time to actually do it.

    I'm not a vet student, but I did spend a night helping one study the sinuses of a large animal (they split in to large animal (farm) and small animal (pet) specialties) and some of the learning materials are a little difficult to wrap your brain around, in particular how the sinuses (voids in the skull) exist inside the skull, how they connect (or don't) and simply where they are. The brain has enough trouble understanding negative spaces, even more trouble trying to conceptualize the winding, twisting 3D negative spaces you can't ever directly view without cutting apart a skull to do so. Even then doing so only gives you half the picture, and in negative space.
     
    There are some videos online showing the sinuses in "positive 3D space" but it's still only a reference (Everyone is different) so I would imagine having a 3D positive space model of a tumor you've never seen and can't see without cutting open someone's head would be incredibly helpful, especially since you can't just buy off the shelf reference material for human tumors like you can bovine sinuses.

The issue here appears to have been the missed diagnosis of optic nerve compression by the tumor.

      RTFA please.
      The description does indeed try to imply that the above is the case. But it's far from the truth, as much as internet armchair experts would like to believe.

      The article itself appears to state that the problem was that 1) the initial advice was to wait, which after (appropriately) consulting with a number of experts they had done, and a followup showed progression. Even the first advice was not totally misplaced. Then what happened was that he suggested that the neurosurgeons basically invent a procedure specifically for him, and used 3D printing to create a model for them. The result was he did find someone willing to try (my guess is they refused the conventional approach) a less invasive procedure that removed 95% of the tumor. Now that may sound revolutionary, but neurosurgery is a tricky business, and depending on the tumor 95% may be equivalent to buying a little time while doing nothing at all, especially since they already knew that the tumor was growing aggressively. If the conventional approach would have had more of a chance of removing more of the tumor, possibly all of it with negative margins, that would be a far more definitive approach. Doctors aren't always right, but if you get a sufficiently experienced expert opinion, it'll usually reflect what is possible to do currently, with a reasonable margin of both safety and success.

      No surprise here. I've recently had to deal with doctors of various kinds, and found many (though not all) to be myopic, stubborn and deeply conservative, reluctant to consult outside their own area of expertise, prone to seek the cause of unknowns outside their own area of expertise ("It's not X, go see a specialist for Y"), and having a disturbing lack of curiosity. Maybe I expect too much of them, but doctors act a lot more like technicians than scientists or researchers. There was an article (in the Economist I believe) about health care being one of the least innovative disciplines. The science of medicine has progressed, but there's been relatively little progress in the way we diagnose and treat patients. Some doctor proudly spoke about how they now employ checklists similar to those being used by pilots, to reduce errors in surgery. A great innovation... which they could have known about and implemented about 50 years ago.

      There are plenty of examples of desperate patients nudging their doctors in the right direction after doing some self-diagnosis and research online. There are also some examples of extraordinary breakthroughs in medical science made by engineers with no medical background.

        Doctors are much more like technicians. You don't want doctors "experimenting" on you unless you really, really need that. Physicians are typically not brought up in a 'science' environment (question assumptions, learning how to research a topic, critical thinking.) Doctors are brought up in 'cram mode'. Dump a lot of into down your throat. You're expected to believe it. They are increasingly taught to 'follow the protocol' which amazingly, is what technicians do.

        Yes, there are 'physician scientists' but they aren't treating the majority of patients and you don't want them to be ('hey that looks interesting, what happens when I tug on it?').

        This case is interesting as the husband of the patient kicked the docs out of 'technician' mode. And, of course, used a 3D printer.

        ALWAYS ask your doc questions about stuff you don't understand.

          To clarify the doctors or physicians you are referring to medical practitioners in medical parlance. There is two additional medical "communities," which are linked, the medical teaching and research specialties though two these tend to be more intertwined. In many cases they share hospitals, labs, institutions.

      Not at all.

Which do you think would solve a complex problem?

I get $600 (about 4 hours of time) to solve the entire wind and seismic resisting system on a small building and if you decide the entire first floor will be all glass I'll tell you you can't do it. If you're an engineer (but not necessarily a structural one) and decide to design a system yourself and you spend 400 hours on it there's a good chance you'll come up with a solution. For $40,000 in your time, you've solved problem worth $600 on the open market.

      And, FWIW, I can solve that kind of problem in under 40 hours - maybe $6000 - but if you offer me $600 to solve the problem, I'm going to tell you that it can't be done [for that money].

        ...except the difference here is that we're talking about someone's life not just a few bucks, and also the doctors didn't say they couldn't do it for the money, they misdiagnosed it the first time, then just said they couldn't do it at all.

    • Yes, absolutely I'm concerned. The radiologist got it wrong in assessing the tumor to have grown. That's so important to a cancer patient as to be an unpardonable sin.

      But given the hodgepodge of modern medical testing, it's not terribly surprising. Clinical CT or MR images often have low resolution or voxels that are anisotropic (usually, longer head-to-toe than side-to-side). When comparing two images with differing resolutions, voxel shapes, or subject poses, two images can be difficult to compare.

    It sounds to me like the actual 3d printing was less important than the 3d model. I'm not sure what the first doctor's problem was. Usually an MRI gives you a detailed model that you can look at from multiple angles. You don't just measure the size from one point of view. That doesn't even make sense.

      The key to success here might have been simply the push for a second opinion. People don't understand that doctors often base their decisions on best practices, and in this case maybe the normal thing for an oncologist would be wait and see how the tumor developed, working out better for 99% of cases. Getting an actual neurosurgeon to look into it was probably the biggest thing, and the 3d print was only useful in catching their attention.

      Granted, 99% of people who tried something like this would have the neurosurgeon look at it, pat them in the head for a good job on the print and then get sent back, as that's the right thing to do. Those are not newsworthy, but that doesn't mean this exception will be the new rule.

      I'd bet on VR to be more useful for doctors as you can see the results right away instead of waiting for the print though.

    this entire story is nonsense, speaking as a qualified medical physicist in radiotherapy with decades of experience. First of all, for him to make a 3D model of a tumour, he is having to decide based on CT and/or MRI data what is or isnt the tumour, which by the way you might have noticed is the same information from the CT and/or MR scan that qualified radiologists and oncologists look at, and using treatment diagnosis and planning software (including auto segmentation techniques). So unless this guy suddenly read a book one night and became a fucking oncologist, he didnt pick out SHIT from a CT data set that a qualified oncologist "missed". Nor did he tell surgeons "how to get at" the tumour in a way that implies that was the holdup, like he figured it out while people who work with this for decades didnt get it.

    ah now wait a minute, halfway down the article

    "So although the first doctors told them to wait, Balzer and Scott sent the MRI results to a handful of neurologists around the country. Nearly all of them agreed that Scott needed surgery."

    correct. OTHER QUALIFIED DOCTORS diagnosed the issue. Not some fucking clown with a 3D printer.

    "The tumor had grown substantially, which indicated a far more grave condition than was initially diagnosed. But back at home, Balzer used Photoshop to layer the new DICOM files on top of the old images, and realized that the tumor hadn’t grown at all — the radiologist had just measured from a different point on the image."

    this makes no sense at all and has either been misreported, or he went to a pretend hospital staffed by retards. NO INFORMATiON WHATSOEVER came to light from a 3D printed model of the SAME FUCKING DATA thats in the image. If someone measured wrong on a scan thats an error, just go back and review the images, or send them off again for a 2nd opinion rather than waste your time printing a fucking useless model

    he sent a 3d model /image round when instead all he had to do was send the SOURCE DICOM files to these other doctors, which would have resulted in the exact same solution.

    Doctors make no profit out of difficult diagnoses. They have a business to run. They're a mill. Get 'em in. Get 'em out. If it looks like something even slightly nonstandard, shove them off to another specialist so that they can bear the cost, and liability. That neurologist isn't going to bother to read the journals, or keep up with technology, or make any extra effort at all. He's got 25 other people to see today and he's already running late and there's a hiring meeting in 20 minutes because the single good support employee his practice has is threatening to quit, and there's another meeting with the lawyer this afternoon about the tumors he missed because he was just too rushed that day.

    Socialized medicine has its own problems, but at least you can get a doctor focused on medicine.

    About two years ago I was at a presentation by a surgeon who used 3d imaging to produce a 3d model of a partially missing bone and a complete symmetric bone. He mirrored the model of the symmetric bone to approximate the part of the missing bone. The part was printed on 3d printer and used to prepare a mold for the appropriate alloy for the implant.

The ally (a savage lady) then makes the tumor, "not be" telekineticly. As the tumor is removed, he as to remake both models as the brain expands back into the empty space. Patient lives.
