ACR® supports collaboration with medical societies that develop clinical practice guidelines, appropriate use criteria, position statements and other communications related to the practice of diagnostic imaging, medical physics, interventional radiology and radiation oncology. We view such collaborations as an opportunity to improve the delivery of patient care and to provide clarity in communicating good medical practices for patients and other stakeholders.

We prefer to be actively engaged in the development or revision of documents, especially if the goal is ACR endorsement. Engaging ACR representatives in discussions about scope, recommendations and clinical issues facilitates the endorsement process.

ACR endorses clinical matters related to diagnostic imaging, medical physics, interventional radiology and radiation oncology only. We require a minimum of 30 days for considering endorsement of documents organized by other societies.

Organizations seeking ACR participation on clinical, practice guidance or other documents may submit requests by first completing the Collaborative Requests Form.

What We Endorse

Types of documents typically considered for collaboration or endorsement.

Statements that include recommendations intended to optimize patient care, informed by a systematic review of evidence and an assessment of the benefits and harms of alternative care options.

Criteria that are evidence-based to the extent feasible and that assist professionals who order and furnish applicable imaging services to make the most appropriate treatment decisions for a specific clinical condition.

Identify, select, assess and synthesize the relevant body of research and help make clear what is known or not known about the potential benefits and harms of alternative drugs, devices and other healthcare services.

The official, published editorial taken by a professional organization regarding best practices, standard of care or inconclusive evidence-based research. Position statements are typically updated regularly.

A document intended to inform practitioners, payers and other interested parties about evolving areas of clinical practice and/or technologies that are widely available or new to the practice community.

These documents are evidence-based whenever possible but tend to be shorter than guidelines and developed around a topic that is more narrowly focused, new or emerging, and for which a smaller body of evidence is available.
