Improved imaging quality produces the most consistent and efficient path to appropriate treatment and accurate diagnosis.
Reduced radiation exposure to patients and healthcare personnel ensure a higher standard of safety.

DiagnosticSite model

DiagnosticSite acts as an imaging network that promotes quality and patient safety through facility ranking. Assessment is administered as an online survey with onsite and desktop audits to verify compliance. Successful completion of the assessment results in certification – see our directory to find a certified facility.


Standards and benchmarking

National standards and benchmarking are established through long-term partnerships with providers, public policymakers, regulators, academic institutions, and other key stakeholders. Health plans also receive guidance and peer-review from DiagnosticSite's Advisory and Standards Committee.


Online Assessment

DiagnosticSite assessment consists of four online modules.

Imaging Provider Information contains facility demographics, including location and contact information.

Imaging Systems and Equipment covers basic information about each imaging device used at the imaging site.

Professional Qualifications asks about equipment operators and the physicians who interpret the results; each facility must submit the expiration date for some licenses, as well as Organization NPI number and ARRT Registries for its technologists.

Quality and Patient Safety includes questions about the recommended safety and quality measures that all imaging providers must meet.


Onsite and desktop audits validate the integrity of DiagnosticSite certification. They help check the accuracy of reported information and ensure the highest standards are delivered. Audits also enable facilities to receive expert guidance in corrective action (as needed) and continuous improvement in radiation safety, quality, clinical practices, and imaging protocols.


HealthHelp reviews completed assessments, certifying those meeting DiagnosticSite quality and safety standards. Facilities that don’t receive certification can improve and reapply within 90 days. Imaging providers must update and re-submit the online assessment prior to expiration, ensuring equipment is functioning properly and technologies are up-to-date with all appropriate licenses.
