ACR requirementsMagnetic resonance imaging (MRI) is an established imaging modality, recognized for its value in the assessment and monitoring of a wide range of cardiac pathology. It can provide physiologic as well as anatomic information. Image interpretation requires both well-developed MRI skills ...

Each of the modules allows flexible protocol choices for clinical image submission, while setting minimum requirements for spatial resolution, temporal resolution, and total scan time. Two phantoms are now available to allow accreditation of both large bore magnets and small bore orthopedic MRI systems...
In its prior format, the ACR MRI Accreditation Program had examination anatomic modules designed primarily to measure quality and validate MR performance primarily in adult imaging practices. In an effort to more closely meet the specific imaging requirements of pediatric patients, an ad hoc MR ...
Also, an accreditation program specifically designed for special-purpose orthopedic systems is under development.%This continuing education course will review the current status and requirements of the ACR Whole Body MRI Accreditation Program, anticipated changes related to the proposed modular program and ...
Results: Scans without normalization failed ACR uniformity (1.5T) and slice thickness requirements and had lower LCD scores. Filtering with the Raw Filter degraded resolution to 1.1 mm and increased the ghosting ratio but resulted in decreased noise. On this scanner 2D (in-plane) distortion ...
