Radiology Associations

Professional radiology organizations connect imaging professionals across the world, and advocate for radiology policies, regulations, educational updates and technology advancements. These societies include ACR, ASRT, SIIM, RSNA, SNMMI, and many other imaging groups. Find specific news pages for each society at these links: American College of Radiology (ACR), Radiological Society of North America (RSNA), American Roentgen Ray Society (ARRS), American Society Radiologic Technologists (ASRT), Association for Medical Imaging Management (AHRA), Radiology Business Management Association (RBMA), Society for Imaging Informatics in Medicine (SIIM), Society of Breast Imaging (SBI), and the Society of Interventional Radiology (SIR).

Mechanical thrombectomy beats anticoagulation alone in STORM-PE
Highly anticipated trial data comparing mechanical thrombectomy to anticoagulation alone for intermediate- and high-risk pulmonary embolism showed that the more aggressive strategy improved outcomes.
Pulmonary embolism thrombectomy use increases by more than 700%
Medicare claims submitted between 2017 and 2022 showed a 712% increase in thrombectomy for pulmonary embolism (PE) and a 137% increase in thrombectomy for deep vein thrombosis (DVT).
