Chronic pain is a nightmare of "invisible" symptoms. If you break an arm, a quick X-ray shows the snap. If you have a tumor, an MRI maps it out in high-contrast detail. But if you have debilitating nerve pain that keeps you awake at 3:00 AM? You’re usually stuck pointing at a smiley-face chart in a doctor’s office. It’s guesswork. Pure and simple. This is exactly what Braxton Norwood and his team at Lutroo Imaging are trying to blow up.
They aren't just making another scanner. They are trying to find a way to actually see pain using a new tool called Radiocaine. It sounds like something out of a sci-fi flick, but it’s currently moving through clinical trials. Honestly, if this works, the days of doctors telling patients "it's all in your head" might finally be over.
The Science of Seeing What Hurts
Most people think of pain as a feeling, but at a biological level, it's a series of electrical signals. These signals fly through your nerves via little gates called voltage-gated sodium channels. When you have chronic pain, these gates often get stuck in the "open" position or start popping up in places they shouldn't be.

Braxton Norwood Lutroo Imaging is betting everything on a radiotracer—essentially a high-tech "dye"—that specifically sticks to these sodium channels. This tracer, known as Radiocaine, is tagged with Fluorine-18.
That’s a fancy way of saying it glows on a PET scan.
Think about the implications. Instead of a patient describing their pain as a "seven out of ten," a physician could look at a PET/MR scan and see a bright cluster of activity in the lower back or a specific nerve root. It’s about moving from subjective stories to objective data.
Why This Matters for the Opioid Crisis
Let's be real: part of the reason the opioid crisis spiraled so out of control is that we didn't have a better way to measure if treatments were working. Doctors were flying blind. They’d prescribe a pill, ask if the patient felt better, and if the answer was "no," they’d up the dose.

Lutroo Imaging’s approach is different. If you can quantify the pain, you can see if a specific therapy is actually calming down those sodium channels. It provides a biomarker. According to Norwood, this could be a game-changer for drug companies too. Instead of waiting years to see if a new non-opioid drug works, they could use Radiocaine to see the biological effect in real-time during trials.
Who Is Braxton Norwood?
You can't talk about the company without looking at the guy behind it. Braxton Norwood isn't just a suit; he’s a PhD in Medical Pharmacology with a heavy background in neuroscience. He’s spent years in the lab, specifically looking at epilepsy and neurological disorders before pivoting toward the massive, under-addressed world of chronic pain.
He’s a "scientist-entrepreneur" based out of Billings, Montana. That’s not exactly the tech hub of Silicon Valley, but Norwood seems to lean into that. He’s founded several companies, including Redpoint Imaging and Expesicor.
But it hasn't all been smooth sailing or laboratory breakthroughs.

The Elephant in the Room: The Legal Record
If you dig into the history of Braxton Norwood, you’ll find a significant complication that SEO-optimized corporate bios usually skip over. In June 2024, Norwood pleaded guilty to a federal charge involving the falsification of records during his time at Expesicor. The case involved how federal grant money from the NIH was handled and reported.
It’s a stark reminder that the world of biotech startups is messy.
While the legal issues were tied to past business practices and administrative records rather than the validity of the science itself, it’s a piece of the story that matters. Most people looking into Braxton Norwood Lutroo Imaging are trying to figure out if the technology is legit or if the leadership is stable. The science behind Radiocaine has continued to move forward regardless of the legal headlines, which suggests the underlying tech has its own momentum.
Where Does Lutroo Imaging Stand Today?
Right now, we are in the "prove it" phase. In late 2024 and heading into 2026, the big news has been the launch of Phase 1 clinical trials. This is the first time Radiocaine is being injected into human subjects.
- The Trial Goal: It’s not about curing pain yet. This phase is about safety, dosimetry (making sure the radiation levels are safe), and biodistribution (seeing where the tracer goes once it’s in the blood).
- The Technology: They are using PET/MR imaging. It’s a dual-threat system that shows both the anatomy of the body and the molecular activity of the nerves.
- The Partnership: Lutroo has picked up some serious street cred lately, winning the AAPM-MIT Hacking Medicine Innovation Challenge. That’s a mouthful, but basically, it means experts from MIT and the American Academy of Pain Medicine think the idea is brilliant.
What This Means for You
If you’re one of the 50 million Americans living with chronic pain, this isn't something you can go buy at the pharmacy tomorrow. Clinical trials take time. However, the shift toward "Precision Pain Medicine" is happening.
The goal for Lutroo Imaging is to make pain diagnosis faster and more accurate. Imagine a future where you don't spend three years seeing five different specialists just to find out why your leg burns. You get one scan, the doctor sees the "hot spot" on your nerve, and you get a targeted treatment—maybe even a non-opioid one—right at the source.
Actionable Takeaways for Patients and Providers
- Follow the Trials: Keep an eye on the Radiocaine Phase 1 results. If the safety profile is clean, Phase 2 will start looking at actual patients with neuropathic pain.
- Ask About Biomarkers: If you’re a provider, start looking into how PET imaging is being integrated into pain management. It’s the next frontier.
- Stay Skeptical but Hopeful: Biotech is high-risk. For every breakthrough, ten things fail. But the move toward objective pain measurement is a necessity, not a luxury.
The story of Braxton Norwood Lutroo Imaging is a mix of cutting-edge pharmacology, high-stakes business, and the very human struggle to make an invisible illness visible. Whether the company scales to a global standard or remains a specialized tool, the conversation around how we "see" pain has permanently changed.
To stay updated on the progress of these diagnostic tools, you should regularly check the FDA’s clinical trial database (ClinicalTrials.gov) for updates on Radiocaine (search identifier NCT07081217) or visit the official Lutroo Imaging site for their latest peer-reviewed publications.
