If carefully adhered to, these restrictions should minimize the risk of two major hazards of MRI — a) projectile accidents and b) injury to patients with implanted devices.Advanced Discussion (show/hide)»Reference ACR Committee on MR Safety. ACR Manual on MR Safety. American College of...
There are several published documents, including the ACR Phantom Testing Guidance and the 2004 ACR MRI QC Manual, which describe the tests and the performance criteria. These documents are helpful in providing guidance on submitting phantom images for accreditation. However, they allow considerable ...
The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where peer reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available ...

Finally, the images were analyzed according to the ACR MRIQuality Control Manual (2001) and the results obtained from the two phantoms were compared. Results: The percent intensity uniformity (PIU) obtained from the oil phantom was at least 6% higher than that from the original phantom (88% ...
