Differences and similarities were identified in testing scope, frequency, and tolerances. QA testing results from an ACR accredited clinical diagnostic MR system following ACR MR QC instructions were then evaluated using TG\u2010284 tolerances.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Five tests from the ACR MR QC Manual were not included in TG\u2010284. Five new tests were identified for MR\u2010SIM systems in TG\u2010284 and pertained exclusively to the external laser positioning system of MR\u2010SIM systems. \u201cLow\u2010contrast object detectability\u201d (LCD), \u201ctable motion smoothness and accuracy,\u201d \u201ctransmitter gain,\u201d and \u201cgeometric accuracy\u201d tests differed between the two QA guides. Tighter tolerances were required in TG\u2010284 for \u201ctable motion smoothness and accuracy\u201d and \u201clow contrast object detectability.\u201d \u201cTransmitter gain\u201d tolerance was dependent on initial baseline measurements, and TG\u2010284 required that geometric accuracy be tested over a larger field of view than the ACR testing method. All tests from the ACR MR QC Manual for a conventional MR system passed ACR tolerances. The T2\u2010weighted image acquired with ACR sequences failed the 40\u2010spoke requirement from TG\u2010284, transmitter gain was at the 5% tolerance of TG\u2010284, and geometric accuracy could not be evaluated because of required equipment differences. Table motion passed both TG\u2010284 and ACR required tolerances.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Our study evaluated QA guidelines for an MR\u2010SIM and demonstrated the additional QA requirements of a clinical diagnostic MR system to be used as an MR\u2010SIM in radiotherapy as recommended by TG\u2010284.<\/jats:p><\/jats:sec>","DOI":"10.1002\/acm2.13730","type":"journal-article","created":{"date-parts":[[2022,7,19]],"date-time":"2022-07-19T06:39:45Z","timestamp":1658212785000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["An evaluation of quality assurance guidelines comparing the American College of Radiology and American Association of Physicists in Medicine task group 284 for magnetic resonance simulation"],"prefix":"10.1002","volume":"23","author":[{"given":"Jacob S.","family":"Buatti","sequence":"first","affiliation":[{"name":"Department of Radiation Medicine Oregon Health and Science University  Portland Oregon USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kyle J.","family":"Gallagher","sequence":"additional","affiliation":[{"name":"Department of Radiation Medicine Oregon Health and Science University  Portland Oregon USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Isaac","family":"Bailey","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology Oregon Health and Science University  Portland Oregon USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"Griglock","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology Oregon Health and Science University  Portland Oregon USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Malcolm","family":"Heard","sequence":"additional","affiliation":[{"name":"Department of Radiation Medicine Oregon Health and Science University  Portland Oregon USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2022,7,18]]},"reference":[{"key":"e_1_2_8_2_1","volume-title":"Magnetic Resonance Imaging Quality Control Manual","author":"Price R","year":"2015"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/mp.14695"},{"key":"e_1_2_8_4_1","volume-title":"Optimizing MRI for Radiation Oncology: Initial Investigations","author":"Balter J","year":"2013"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.mri.2012.04.010"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijrobp.2017.06.006"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/acm2.13236"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.phro.2020.09.009"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1118\/1.2359229"},{"key":"e_1_2_8_10_1","unstructured":"Accreditation of advanced diagnostic imaging suppliersCMS.
