Imvoc

What Imvoc does

Imvoc (Imagerie Médicale Val d'Ouest Charcot), legally structured as a SELARL headquartered in Tassin-la-Demi-Lune, is a private medical imaging group operating 7 centers across the Lyon metropolitan area. The group was formed from the merger of the radiology practices of Cliniques Charcot and Val d'Ouest and has expanded through the absorption of 5 additional radiologists from L'Arbresle and Écully in 2023. It is staffed by 24 superspecialized radiologists organized by clinical domain (breast, pediatric, interventional, neurological, oncological, etc.), supported by 40 radiology technicians, 49 medical secretaries, and 8 administrative staff, with academic affiliations to Hospices Civils de Lyon.

The group's service portfolio spans the full diagnostic imaging spectrum: conventional radiography (9 digital rooms), low-dose EOS full-body 3D X-ray (2 systems), mammography with 3D tomosynthesis (6 units including 3 with tomosynthesis), bone densitometry (4 units), ultrasound (16 machines with endocavitary, 3D, and fusion imaging), multislice CT (3 scanners), and MRI (5 machines: 2 at 3T, 3 at 1.5T). It operates an integrated PACS and RIS network enabling real-time inter-site image transmission. Interventional radiology is a distinct service line covering biopsies, thermoablations, infiltrations, and the dedicated Embolyon embolization pathway, with a new interventional CT scanner arriving in 2026 (first private such equipment in Auvergne-Rhône-Alpes). AI tooling is integrated via Gleamer (fracture detection, bone age, orthopedic measurements) and GE AIR DL deep learning reconstruction for MRI. Exclusive technology partnerships include GE HealthCare for angio-mammography macro-biopsy (only private center in France offering this).

Imvoc generates revenue primarily through procedure fees reimbursed under the French national health insurance system (Assurance Maladie) and complementary mutuelles, following the standard French medical fee schedule. Patient acquisition is driven by referrals from GPs, specialists, and hospital physicians, supplemented by direct online appointment booking and a growing patient portal for results access. The group participates in national screening programs (IMPULSION lung cancer screening with INCa, organized breast cancer screening via ADEMAS) and operates a shared GIE (GIE Imagerie Sud) facility with Centre Hospitalier Lyon Sud. Ownership is held by its physician members, with no external institutional investors or parent holding company disclosed.

Revenue model

1. Medical imaging and radiology services: IMVOC operates as a medical imaging provider reimbursed through the French national health insurance system (Assurance Maladie). Services include radiography, mammography, EOS, ultrasound, CT scanning, MRI, and interventional radiology procedures. Revenue is generated through procedure fees covered by social security and complementary health insurance (mutuelles).
2. Interventional radiology procedures: Minimally invasive therapeutic procedures including biopsies, infiltrations, drainages, thermoablations, and embolizations. These are performed in clinic settings and billed through the French healthcare system. The group has developed a dedicated Embolyon center for embolization procedures.

Expansion highlights6 records

Emerging players

• Doctolib: Dominant French healthcare booking and telehealth platform increasingly involved in imaging appointment coordination. Comparable as an emerging digital health platform shaping patient referral and appointment flows relevant to IMVOC's patient acquisition model.
• Median Technologies: French AI-driven medical imaging analysis company focused on oncology trial imaging and clinical decision support. Comparable as an AI imaging technology player with clinical workflow integration, but software-focused rather than service-provider.

Broad incumbents

• Ramsay Santé: Leading French private hospital group operating imaging services within its clinics. Comparable as a major private-sector healthcare services provider in France with imaging offerings, but operates at much larger scale and broader service scope than IMVOC.
• Synlab: Europe's largest medical diagnostics services provider with broad laboratory and imaging footprint. Comparable as a multi-site European diagnostic operator, though Synlab is biology-led and operates at vastly greater scale.
• Vivalto Santé: French private hospital group operating clinics with diagnostic imaging services in multiple regions. Comparable as a French private healthcare provider offering imaging alongside other specialties, but at significantly larger scale.
• Unilabs: European diagnostics group offering medical laboratory, imaging, and pathology services across 15+ countries. Comparable as a multi-modality European diagnostic operator, but broader in scope and geography than IMVOC's Lyon-focused radiology practice.
• Elsan: Major French private hospital and outpatient services group with imaging capabilities embedded across its clinics. Comparable as a large French private healthcare operator with imaging services, though much broader in service mix and footprint.

Direct peers

• Vidi: Federated network of French private radiology groups operating across multiple regions. Most direct structural comparable to IMVOC given similar SELARL-based, superspecialized radiologist model serving GP and specialist referrals.
• Cerba Healthcare: French-headquartered specialty diagnostics and clinical laboratory network with growing imaging exposure. Comparable as a French private diagnostic services group operating across multiple sites with similar referral-driven revenue model.
• Inovie: French private diagnostic network offering medical biology and imaging services across multiple regions. Comparable as a multi-site French diagnostics operator competing for the same referring physician ecosystem, though Inovie is biology-led and significantly larger.
