OTHER MARKETS · MARKETS TO REGIONS

We didn't export one house style to thirty-two countries. We built the governance to run each market to its own standard, and resourced the US practice accordingly, so yours is never the compromise.

Protocol & Template Governance

Templates, terminology and formats set per market and per client, then locked and version-controlled.

Subspecialty Routing

A spine MRI goes to a neuroradiologist, not to whoever is next in the queue.

Peer Review & Scoring

    Clinical Lead, Radiologist Engagement


In 1983, Dr. Prathap C. Reddy opened India's first corporate hospital so patients would no longer have to leave the country for world-class care. That idea became a network of more than 75 hospitals and one of Asia's largest diagnostic footprints. Reading at that volume forced solutions most practices never need: routing every study to the right subspecialist, scoring every read, and closing every discrepancy on a clock. Apollo Radiology International takes that discipline outward. Not as one template for every country, but as practices built to local standards. In the US, that means US-based radiologists working to ACR practice parameters, with their own clinical leadership.

Overflow relief, overnight coverage, or a subspecialist you can't hire locally, delivered by US-based radiologists to ACR practice parameters, with a staged transition built around your team.
