![]() Please refer to the ACR Quality and Patient Safety/MR Safety web page for more information on IV contrast safety.Ĭategory B: Anatomic Coverage and Imaging Planes Proper anatomic coverage and imaging planes are important components of clinical MRI exams. If contrast is required, it is very important that patient selection is appropriate for the examination using contrast. You must submit localizer or scout sequences with cross-reference locations for each clinical examination.Īll sequences must demonstrate sufficient Signal to Noise (SNR), and not appear too grainy. IF ANY OF THESE SEQUENCES IS NOT SUBMITTED, THE EXAMINATION WILL FAIL. If your facility performs more sequences than the required minimum, you should submit these additional sequences. ![]() Our articles on examination-specific parameters detail the sequences considered to be the minimum necessary for a quality examination. TR, TE, FA, ETL, etc.) are not specified and are left to the discretion of the imaging facility unless otherwise stated. conventional SE, multishot RARE or gradient echo) and the precise imaging parameters (e.g. Exam IdentificationĬategory A: Pulse Sequences and Image Contrast The type of pulse sequence (e.g. The categories for scoring examinations submitted for ACR MR Accreditation are: A. The intention of accreditation is to provide guidelines on what constitutes optimal image quality above that which is normally acceptable and to promote the best practice at all times. Despite this variability, experienced interpreting physicians are able to agree on what constitutes “acceptable” and “unacceptable” diagnostic exams based on both objective and subjective criteria. The pulse sequences that are used clinically for examinations of different body regions are variable due to the personal preferences of users as well as the capabilities of the different MRI systems. The sequences required for accreditation submission should not be construed as a complete clinical exam. Although some criteria for MRI examinations are requirements for accreditation, others are only intended as a guide technique parameters mentioned are only suggestions unless otherwise stated. Prior to submission of any images for evaluation, the interpreting physicians and technologists at your facility must review the accreditation criteria detailed here. The requirements used by the accreditation reviewers represent a technical baseline for producing acceptable diagnostic examinations. *If the unit performs and applies for the cardiac or breast modules only, a total of 2 delayed enhanced cine with black blood exams or 2 MR breast exams with known, enhancing biopsy-proven carcinoma are required Select 1 examination from each module, and select 1 additional examination from any of the 3 modules The number of required examinations is based on the number of modules your site selected on the application:
