St. Luke’s University Health Network has become the first health care system in the region and one of the first nationwide to implement AngioFlow™ by RapidAI, a breakthrough perfusion imaging technology.
AngioFlow is an advanced brain blood flow imaging tool used for acute stroke evaluation, said Dr. Martin Oselkin, neurointerventional radiologist. Traditionally, patients are sent to a CT scanner for perfusion imaging to help physicians make the decision for thrombectomy (clot removal) or not, but AngioFlow allows St. Luke’s to skip the CT scanner and perform the perfusion study right in the operating room.
“This results in at least 35 minutes in time saved,” Oselkin explained, “which is vital to patient outcomes, as 1 million brain cells die with each minute that passes before a clot is removed.”
The advancement further strengthens St. Luke’s position as the regional leader in advanced stroke diagnosis and treatment – and is a testament to St. Luke’s overall excellence. This past fall, the U.S. Department of Health and Human Services ranked St. Luke’s #1 – ahead of Houston Methodist and Mayo Clinic, two of the nation’s most prestigious institutions – as the nation’s top health system for quality, safety, and patient experience. This objective recognition, based on public data reported to the government, reaffirmed St. Luke’s preeminent position among the leading health systems in the country.
AngioFlow is now available at St. Luke’s University Hospital in Bethlehem, a Comprehensive Stroke Center recognized for providing the highest and most advanced level of stroke care and serving as the Network’s hub for leading stroke and neurovascular capabilities.
For patients, the benefits are significant. Real‑time perfusion imaging supports:
- Shorter procedure times, which can directly improve outcomes in stroke.
- Earlier identification of salvageable brain tissue, increasing the chance of functional recovery.
- More precisely tailored interventions, reducing the risk of complications.
- Enhanced safety, as clinicians have immediate insight into how treatment is affecting blood flow in real time.
At St. Luke’s, these advanced stroke and neurovascular interventions are performed by Oselkin and endovascular neurosurgeons Dr. Evan Marlin and Dr. Nathan Quig. Together, they lead the Network’s commitment to elevating stroke care across the region through innovation, rapid response and leading‑edge technology.

About St. Luke’s
Founded in 1872, St. Luke’s University Health Network (SLUHN) is a fully integrated, regional, non-profit network with annual net revenue of more than $4.5 billion. With 23,000+ employees at 16 hospital campuses and 350+ outpatient sites, it is the Lehigh Valley’s biggest employer.
The Network’s service area includes 11 counties in two states: Lehigh, Northampton, Berks, Bucks, Carbon, Montgomery, Monroe, Schuylkill and Luzerne counties in Pennsylvania and Warren and Hunterdon counties in New Jersey. St. Luke’s Children’s Hospital is based at the Bethlehem Campus.
Dedicated to advancing medical education, St. Luke’s is the preeminent teaching hospital in central-eastern Pennsylvania. In partnership with Temple University, the Network established the Lehigh Valley’s first and only four-year medical school. It also operates the nation’s oldest continuously operated School of Nursing, established in 1884, and 60+ fully accredited graduate medical educational programs with 550+ residents and fellows.
In 2025, the U.S. Department of Health and Human Services ranked St. Luke’s #1 – ahead of Houston Methodist and Mayo Clinic, two of the nation’s most prestigious institutions – as the nation’s top health system for quality, safety and patient experience. This objective recognition, based on public data reported to the government, reaffirms St. Luke’s preeminent position as THE BEST OF THE BEST among the most respected health care systems in the United States.
St. Luke’s has been named a Leapfrog Group and Healthgrades Top Hospital and a Newsweek World’s Best Hospital. It is the only Lehigh Valley-based health care system to earn Medicare’s five-star ratings (the highest) for quality, efficiency and patient satisfaction. In 2025, the Network earned straight A’s from Leapfrog across all of its acute care hospitals. It has earned 100 Top Hospital designations from Premier 11 years in a row, including in 2021 when its flagship University Hospital was identified as THE #1 TEACHING HOSPITAL IN THE COUNTRY. Utilizing the Epic electronic medical record (EMR) system for both inpatient and outpatient services, the Network is a multi-year recipient of the Most Wired award recognizing the breadth of SLUHN’s information technology applications such as telehealth, online scheduling and online pricing information.
