Clinical Guidelines

Appropriate Use Criteria (AUC)

Appropriate Use Criteria (AUC) are statements that contain indications describing when, and how often, an intervention should be performed under the auspices of scientific evidence, clinical judgment, and patient values while avoiding unnecessary provisions of services. SNMMI follows a balanced multidisciplinary approach to guidance development by including various stakeholders in the development process.

Procedure Standards

SNMMI, an international scientific and professional organization, periodically defines new procedure standards for nuclear medicine practice to help advance the science of nuclear medicine and to improve the quality of service to patients. Each procedure standard has undergone a thorough consensus process in which it has been subjected to extensive review. They are intended to assist practitioners in providing appropriate nuclear medicine care for patients. SNMMI partners with other medical societies, especially EANM, to ensure the procedure standards are comprehensive and inclusive. 


The Medical Internal Radiation Dose Committee pursues its mission to develop standard methods, models, and mathematical schema for assessing internal radiation dose from administered radiopharmaceuticals. The Radiation Dose Assessment Resource website's goals are to bring together the various resources that exist in the areas of internal and external dose assessment, integrate them into a single system, and put them in your hands as quickly and efficiently as possible.

Dose Optimization

In nuclear medicine and molecular imaging, small amounts of radioactive agents are administered to the patient to allow the physician to examine molecular processes within the body. These procedures are highly effective, safe and painless diagnostic tools that present physicians with a detailed view of what’s going on inside an individual’s body at the cellular level. For more than 60 years, these studies have been used to evaluate practically all systems within the body, including the heart and brain, as well as to image many types of cancer.

Consensus Guidelines and Position Statements

Consensus Guidelines are statements on issues or procedures within the field of nuclear medicine that are supported by other medical specialty societies and experts. The statements are intended to guide credential bodies that privilege physicians to perform procedures and to provide guidance and recommendations on procedures for which randomized prospective trial data is not available.
