Diagnostic Imaging Centers

NAICS 621512 · Ambulatory Health Care Services · SBA size standard: $19 million average annual receipts

Diagnostic imaging centers receive physician referrals, schedule patients for MRI, CT, X-ray, ultrasound and other scans, prepare patients according to protocol, perform the imaging studies, route images for radiologist interpretation, deliver signed reports to referring physicians, and manage contrast inventory, equipment maintenance, safety logs and billing. Specialists turn referrals into verified orders ready for scheduling, verified orders into scanner bookings with prep instructions, completed scans into routed reading queues and finalized reports, while tracking inventory, maintenance and regulatory paperwork that the center's staff review and approve.
