Marquis Medical PET & CT Service
What We Do:
Medical imaging includes a wide range of modalities—MRI, CT, Ultrasound, X-Ray, SPECT, and PET/CT, to name a few. Many companies claim to service and sell equipment across all of them. At Marquis Medical, we take a different approach: we focus.
Our focus is PET/CT—exclusively.
Founded by PET/CT experts Kevin McGehee and Joe Sciarra, Marquis Medical is built on a deep, specialized knowledge of this modality. Our service technicians and reconditioning team are highly trained to support every aspect of PET/CT systems—from service and repair to parts and complete scanner sales.
Because PET/CT is all we do, our customers know they’re getting cost-effective, high-quality solutions tailored to this specific technology. Whether you're inquiring about service, reconditioned parts, or a complete PET/CT scanner, you’re working with a team that knows this equipment inside and out.
We’re not trying to be the biggest imaging company in the world—just the best at what we do. And when you call or email us, you can expect to hear back directly from our founders. Contact us today and let us help you improve your PET/CT facility.

Meet The Team
Kevin McGehee
Principal
Kevin holds a degree in Biomedical Equipment Technology and began his career as part of the biomedical engineering staff at a major hospital in Baton Rouge, LA. It was there that he gained a deep appreciation for the importance of quick repair turnaround times for clinical staff.
He earned certification as a Diagnostic Radiology Systems Specialist and was responsible for maintaining the hospital’s imaging equipment. Kevin later joined CTI as a Regional Service Manager, overseeing PET and PET/CT service operations.
Following CTI’s transition to Siemens, Kevin and his partner Joe identified a gap in the PET and PET/CT service market. In 2006, they co-founded Marquis Medical to address that need.
