The rationale behind the ACR's 4-zone strategy is to make it difficult for unqualified staff and unscreened patients to reach the potentially dangerous inner sanctum of the MRI Center (Zone IV). If carefully adhered to, these restrictions should minimize the risk of two major hazards of MRI ...
For instance, iodinated contrast agents are commonly used in CT scans, while gadolinium-based contrast agents are preferred for magnetic resonance imaging (MRI). 4. Timing and Dosing: The guidelines emphasize the importance of proper timing and dosing of contrast agents. The optimal timing of ...
The most recent version addresses new sources of risk of adverse events, increases awareness of dynamic MR environments, and recommends that those responsible for MR medical director safety undergo annual MR safety training. With regular updates to these guidelines, the latest MR safety concerns can ...
CT provides complementary information regarding bony anatomy, and may be appropriate as a first-line test in certain instances, but it provides less detail and lesion characterization when compared to MRI. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for ...
The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals...
MRI Suite: ACR Safety ZonesWhat are the ACR Safety Zones? The American College of Radiology has defined four safety zones within MRI facilities. These are denoted Zones I through IV and correspond to levels of increasing magnetic field exposure (and hence potential safety concern)....
2007 ACR Guidelines Stress New Safety Information The article discusses the changes to the document "ACR Guidance Document for Safe MR Practices: 2007," which has been released online by the "American Journal of Roentgenology" (AJR) and the American College of Radiology (ACR). The subst... T...

Other imaging and noninvasive physiologic tests may prove important for longer term management but are less recommended in the acute setting. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a ...
Many important clinical questions addressed in the guidelines do not lend themselves to clinical trials. Even though randomized trials are not available, there may be a very clear clinical consensus that a particular test or therapy is useful or effective. †For comparative effectiveness ...
