Steinberg Diagnostic Medical Imaging

What Steinberg Diagnostic Medical Imaging does

Steinberg Diagnostic Medical Imaging (SDMI) is a Las Vegas-based outpatient diagnostic imaging operator founded in 1988 by Dr. Leon Steinberg, Dr. David Steinberg, and Dr. Mark Winkler. As of January 2026, SDMI operates 12 imaging centers across the Las Vegas Valley with approximately 550 employees and affiliates, including about 30 subspecialty-trained radiologists, and was acquired by Intermountain Health in January 2026 to extend the hospital system's reach to roughly 350,000 southern Nevadans.

The company's service portfolio covers MRI, CT, PET/CT, 3D mammography, ultrasound, X-ray, nuclear medicine, DEXA, fluoroscopy, low-dose lung cancer screening, interventional radiology, and pediatric imaging. Equipment is anchored on Canon Medical Systems platforms (Aquilion Serve SP CT, Vantage Galan 3T Supreme MRI, Cartesion Digital PET/CT), supplemented by AI features such as AI-enhanced 3D mammography, AI deep learning reconstruction for cardiac scoring, INSTINX automated CT workflow, and the Emma virtual assistant built on the Genesys Cloud contact center platform. SDMI holds AAAHC accreditation across all locations since 2011 and was the first practice in Nevada to achieve ACR Diagnostic Imaging Center of Excellence status.

SDMI generates revenue primarily through insurance-reimbursed, fee-for-service diagnostic imaging procedures billed to a broad mix of payers, supplemented by self-pay offerings (e.g., Ezra full-body MRI cancer screenings) and physician-channel referrals managed through a dedicated account manager program, online portal, and call center. The company has no public stock listing, no disclosed institutional funding, and operates as a subsidiary of Intermountain Health following the 2026 acquisition.
