Redefining surgical precision: How intraoperative portable imaging provided immediate feedback and eliminated the need for repeat surgery.
A neurosurgery team at the London Health Sciences Centre (LHSC), led by neurosurgeon Dr. Neil Duggal, achieved a world first this past October: using the Hyperfine Swoop® portable MRI system directly inside the operating room to guide the removal of a complex pituitary tumor. A look back at a medical breakthrough that is redefining the standards of surgical precision.
Technological innovation in healthcare finds its true meaning when it secures medical procedures and tangibly improves patients’ lives. This is exactly what happened at LHSC in Ontario, marking a historic milestone for neurosurgery and Point-of-Care imaging.
The Challenge: Navigating high-risk anatomy
The pituitary gland is a small, pea-sized structure essential for regulating many bodily functions. Although most pituitary tumors are benign, their location makes interventions extremely delicate.
During endoscopic surgery (a minimally invasive approach through the nasal cavities), the surgeon faces a tight and complex area. As Dr. Duggal explains, the operation is akin to “draining an eggshell without violating its boundaries.” The tumor is surrounded by critical structures: the carotid arteries on the sides and the optic nerves on top.
The major challenge? A lack of comprehensive visibility during the intervention. It is often difficult to visually confirm if the entire tumor mass has been safely removed. Leaving residual tumor tissue increases the risk of regrowth and, consequently, the need for a second surgical intervention.
The Solution: Swoop® Intraoperative MRI, immediate feedback
This is where the Hyperfine Swoop® portable MRI comes into play. Unlike a traditional MRI that requires transporting the patient—a cumbersome, lengthy, and risky logistical effort mid-surgery—the Swoop® system was brought directly to the patient’s bedside, right inside the operating room.
This intraoperative imaging provided the surgical team with immediate visibility into this complex area of the brain, validating the work done.
“Having access to a portable MRI during surgery was a game changer in our ability to be as precise as safely possible, within a single procedure. Eliminating a potential repeat surgery, I think that’s a game changer!” — Dr. Neil Duggal, Neurosurgeon at LHSC.

The Human Impact: Dave Evans’ Story
Behind this technological feat is the story of 65-year-old Dave Evans. For several years, this father of three had been suffering from chronic headaches and a progressive loss of his peripheral vision.
To describe his silent ordeal, Dave uses a striking metaphor:
“If you had a TV set and the quality diminished one percent per month, it’s not that detectable, but after a while, it really is diminished.”
Using the Swoop® during his surgery not only spared him a second operation but also offered him invaluable peace of mind. As soon as he woke up in the recovery room, the results were evident: his eyesight had improved almost instantly, and his headaches were gone.

“To have my health back and be able to enjoy life with my wife and my children is great. It was the best, most timely care possible and gave me so much confidence in my recovery,” he shared, relieved and euphoric.
