TL;DR it can be hard to obtain, view, and share medical images of your own body. Scroll down for a cool video of the inside of my knee derived from a CD with DICON images on it uploaded to a cool open source viewer.
I have had persistent and increasing knee pain in my left knee for about five years. It’s a real bummer. I’ve tried to get it fixed various times:
- physiotherapy for a few months in Vancouver in college
- one chiropractor visit in Vancouver who looked at a pendulum and told me the cause was that I was “standing wrong”
- more physiotherapy in San Francisco
- bone scan, x-ray, and MRI imaging where everything looked ok
- Platelet-Rich Plasma (PRP) injections that cost $2500 and did nothing
- most recently, even more physiotherapy in the East Bay
It’s gotten significantly worse this year despite (accelerated by?) the physio, and I’d really like to get to the bottom of it, if there is a bottom to get to. I’d like to get some more imaging done and see if anything has changed that might indicate any missing treatment paths. If all still “looks good”, I’ll double down on the yoga, physio, and stretching.
This is the short, rant-ey story of trying to get the medical images of my knee (bone scan, x-ray, and MRI) that were taken in the past so that I can provide them to a referred specialist.
I got these images at Sutter Health from a doctor famous for undergoing knee surgery without anaesthetic to figure out where we feel knee pain:
This led him to ask the question, “What anatomic structures in the knee can really feel pain?"…To answer the question, Dye asked a colleague to perform knee arthroscopy on his knee without anesthetic.
During the arthroscopy, the surgeon would probe different anatomic structures, and Dye would report what he felt. He described both the intensity of the sensation and whether he could localize the sensation. As a result, he discovered that he had almost no pain with palpation of the patellofemoral joint, while probing of the anterior fat pad and anterior joint capsule was exquisitely painful. Correctly identifying the anatomic structures that lead to knee pain should help provide direction for treatments in the future.
Dr. Dye did not look so hot when I saw him for treatment - it looked like he had fallen and scraped up his face and arm pretty badly. He didn’t offer an explanation and I didn’t ask.
After looking at the images and telling me nothing stood out, he offered to give me a steroid injection right then and there for something like $500. It “might help ease the pain for up to 6 months, at which point we’d do another one, but their effectiveness wears off after the third or fourth one”. Disappointed that this was the latest recommendation from someone who had done such cool research, I passed.
A while later, I requested the bone scan, x-ray, and MRI results from his office. They told me I could pick it up in person only - no email or physical mail options were available. I showed up at the door and received an envelope from a masked assistant through a crack in the door (this was early in COVID times).
Unopened, I delivered the envelope to another specialist.
Recently, I requested the images again, only to find that Dr. Dye’s office, the “San Francisco Knee Clinic” had disappeared. The decrepit Facebook page held a number that rang forever, Google Maps called it “Closed”, and Sutter had no information about where he had gone.
They did tell me to call the imaging department, which I did, and they told me to come pick up the images in person.
I showed up downtown the next day and received an envelope. I opened it.
Me: “Where are the images of my knee?”
CD Master: “They’re on the CD”
I had missed that there was a physical CD at the bottom of the envelope.
Me: “Can you print them for me?”
CD Master: “We don’t print images.”
Me: “Can I get it on a USB drive?”
CD Master: “…no”
CD in hand, I left pretty sad. I didn’t know how I’d read a CD. What if I scratched it, or a crow saw its shine and stole it for its nest of treasures? I called the library on the suggestion of my partner, but the library didn’t know how to read one either. I talked to a print shop, and they told me in many many words that them being able to read it depended on the kind of CD it was.
Finally, I found and ordered a CD/DVD drive off Amazon.
It arrived today, and I excitedly popped the CD in and plugged the drive into my USB dock. The
appeared, but decided to unmount every time I tried to view or copy any files.
After unplugging everything else from my dock to try to provide the drive a steady power source and turning it on and
off again, I was able to
sudo cp -r PATIENT_DATA/* ~/leo-knee.
I immediately version controlled this folder with
git and a remote in the cloud, HIPAA be damned (can you break HIPAA
for your own medical data? Someone probably knows).
Expecting to find some PDFs of my knee with big red arrows to the important bits, I was surprised to find no obvious image files in the contents of the CD:

It looks like the CD came with a directory of files in DICOM format, which I’ve learned today is a standard for medical imaging data. When you see the Radiologist scroll through your body slices like you’re in a Body Worlds exhibit, I guess they’re often using a DICOM viewer.
It also came with a copy of DICOM viewer OsiriX, an
application that “needs to be updated to run on my Mac” and costs 90€/month. The
Images directory just contained a few
icons used in this app.
This was written by one person, Alex Bettarini, making $8/month on Patreon currently. Alex, we love you and I will be giving you some money.
Importing all the DICON files into Miele-LXIV was fast and simple and it was pretty cool and scary to scroll around my knee and leg bone slices.
There was a movie export option, so finally, here is what my knee looked like from the inside a while ago:
So what have I learned?
- Be very diligent about medical records, particularly in the United States of America (I was not and have learned my lesson)
- Medical images are probably not pdfs, which is why folks don’t/won’t print them or email you them or whatever (also probably privacy reasons)
- I am once again happy I am ok at computers and good at Googling things
What remains to be seen:
- How will I share these DICON images? Maybe I can just email them to my Doctor? Is that in any way legal, encouraged, or helpful?
