What Westwood Open MRI does

Westwood Open MRI & Ultrasound is a single-site diagnostic imaging center located at 10921 Wilshire Blvd. (Mezzanine Level) in Los Angeles, California. Founded in 2007 and operating under the corporate umbrella of Rezolut (with Centrelake Medical Group, Inc. as a partner network), the facility is ACR accredited and delivers MRI, Functional MRI (fMRI), and ultrasound imaging services to individual patients, referring physicians, and insurance/lien case patients in the Los Angeles metropolitan area.

The center's technology stack centers on a Siemens Espree 1.5T MRI system with a 70cm open bore and 550lb table capacity — addressing claustrophobia and bariatric accessibility — and on SubtleHD™, an FDA-cleared AI-powered image enhancement tool licensed from Subtle Medical that reduces scan times by approximately 41% (up to 67% on certain protocols) while preserving diagnostic accuracy. Ultrasound services use a 3D/4D volume transducer with Auto Doppler for vascular and anatomical assessments. Patient and referring physician portals provide self-serve image and result access, and billing is processed through ImaginePay.

Revenue is generated transactionally through insurance claims (PPO, Medicare, Workers Compensation, Personal Injury Protection, Letters of Protection) and self-pay/payment plans for uninsured patients. Go-to-market combines direct-to-consumer appointment scheduling with a physician-referral channel anchored by a dedicated referring physician portal, fillable referral forms, and insurance network participation. No public funding, M&A, leadership, or financial disclosures are present in the available source material, and the company operates from a single facility with no disclosed expansion plans.

Direct peers

• RadNet, Inc. The largest outpatient imaging network in the United States and the dominant diagnostic imaging operator in the Los Angeles market. Directly competes with Westwood on MRI, ultrasound, and other modalities across overlapping geographies and payer contracts.
• Tower Imaging Medical Group: Los Angeles outpatient radiology practice offering MRI, CT, PET/CT, ultrasound, and women's imaging. Competes for referring physicians and patients seeking high-quality community imaging in overlapping LA-area service zones.
• RAYUS Radiology: National outpatient imaging provider (formerly Center for Diagnostic Imaging) offering MRI, CT, and other modalities with a similar community-based, physician-referral-led model. Operates imaging centers across multiple U.S. markets with comparable patient mix.
• SimonMed Imaging: National outpatient imaging chain with significant Southern California presence. Offers MRI, CT, ultrasound, and other modalities in a similar outpatient, multi-payer model, directly competing for physician referrals and self-pay patients.
• Beverly Hills Imaging Center: Los Angeles-area outpatient imaging center providing MRI, CT, ultrasound, and X-ray services. Directly competes for the same referring-physician and self-pay patient base on the Westside of Los Angeles.

Others

• Subtle Medical: Technology partner that supplies the FDA-cleared SubtleHD AI image-enhancement software used by Westwood. Included as an adjacent ecosystem participant rather than a competitor — its adoption by other imaging centers directly affects Westwood's technology differentiation.

Broad incumbents

• UCLA Health Radiology: Academic medical center imaging service offering a full spectrum of diagnostic and advanced imaging, including fMRI. Competes with Westwood for neurology, neurosurgery, and complex outpatient imaging referrals on the Westside of Los Angeles.
• Cedars-Sinai S. Mark Taper Foundation Imaging Center: Hospital-affiliated outpatient imaging program of a major Los Angeles academic medical center. Offers MRI, CT, PET/CT, and specialty imaging as part of a broader health system, competing with Westwood for higher-acuity referrals and complex imaging cases.

Emerging players

• Prenuvo: Emerging preventive whole-body MRI provider with growing Los Angeles-area presence. Targets a partially overlapping cash-pay consumer segment with a different value proposition (screening vs. diagnostic), but competes for the same direct-to-consumer MRI demand.

Regional players

• MemorialCare Imaging Center: Southern California health system outpatient imaging network offering MRI, CT, ultrasound, and women's imaging. Competes for community referrals in the broader LA/Orange County region, though with a different geographic focus than Westwood's Westside concentration.
