The American College of Radiology (ACR) has released three new medical imaging guidelines and revised nine others.  The evidence-based guidelines assist physicians and other providers in making the most appropriate imaging or treatment decisions.

The new guidelines cover:
 

• Lung cancer screening
• Postmenopausal subacute or chronic pelvic pain
• Suspected new-onset and known nonacute heart failure
   

The revised guidelines include:
 

• Chronic knee pain
• Breast pain
• Suspected appendicitis
   

ACR said it conducts a two-month focused comment period following the release of new or revised guidelines.
