Detailed information on the ACR MRI accreditation phantom can be found in the ACR documents, “Site Scanning Instructions for Use of MR Phantom for the ACR™ MRI Accreditation Program” [10] and “Phantom Test Guidance for the ACR MRI Accreditation Program” [11], which are available on the...
Our results indicate that silicone oil is more suitable for use in the routine quality assurance test at high field by minimize the effect from the phantom materials. Filling the ACR MRI phantom with silicone oil permits the same testing procedures without compromising the action criteria for the ...
Since prognosis is mainly determined by cardiac involvement, T2* quantification within the LV myocardium has been shown to be a more efficacious marker of cardiac iron involvement and guidance of chelation therapy than serial liver biopsies (203, 204). 3.5.9. Potential Advantages of CMR Relative ...
High-contrast resolution, slice thickness, and low-contrast detectability (LCD) were evaluated manually for all scans following the recommendations in the ACR's Phantom Test Guidance manual (http://www.acr.org/~/media/鈭 /media/ACR /Documents/Accreditation/MRI/LargePhantomGuidance.pdf). Results: ...
