Largest radiology physician group practices

When you’re selling a healthcare product, software, or service, physician groups can be appealing targets. These multi-practice providers tend to centralize their purchasing decisions, enabling bulk sales and long-term partnerships.

To maximize the impact of your marketing to physician group practices, you should use market intelligence to identify the most valuable targets. Physician group size and specialty are two useful metrics for narrowing your target list. How many radiology physician group practices are there in the U.S.?

Our database has data on 1,748 active radiology physician group practices in the U.S. However, physician groups usually operate several different locations to maximize patient access. Because of this, the number of physician group practices does not reflect the number of radiology practices in the United States.

Why target radiology physician groups?

Targeting a private practice doctor instead of a hospital or health system can make it easier to connect with executives and decision-makers. Since many private practice doctors are part of a physician group, they should be a key target for your marketing efforts.

The doctors at radiology physician groups are specialists in diagnosing and treating injuries and diseases using medical imaging procedures, such as magnetic resonance imaging (MRI), computed tomography (CT), X-rays, and ultrasound. Radiologists require proper technology, equipment, and staff training—typically acquired from organizations like yours—to improve their patients’ health outcomes and quality of life.

Tips for targeting radiology physician groups

The challenges and priorities of each physician group are unique, so your marketing approach should be unique for each group, as well. Leverage information like tech install data, procedure and claims data, and Medicare charges to personalize your outreach for maximum efficiency.

Focus on how your product, technology, or service can improve patient outcomes, enhance diagnostic capabilities, or optimize operations—whichever challenges are most pressing for the physician group.

Showing real-world applications of your solution and the benefits it provides can help the physician group see how your product, software, or technology can help their specific scenario.
