An automatic MRI quality control procedure: Multisite reports for slice thickness and geometric accuracy

Abstract : In this work, we report multi-scanner quality control monitoring using a standard and automated protocol. This magnetic resonance imaging quality control protocol, based on the American College of Radiology procedures, includes weekly scans of a dedicated phantom followed by specific measurements. The processing step commonly involves manually-performed operations which can be tedious and time-consuming hence motivating their automation. QC data were collected in four sites; data from one of them served for the validation of the automatic analysis tool. Designed as a package of MATLAB® functions, this tool was successfully validated using Student's t-test and the correlation between automatic measurements and the manual ones. Besides, the multisite QC study enabled to compare the performances of these four MR facilities. In order to avoid misinterpretation or errors in multicenter clinical studies, such approach can be recommended as a preliminary step for including a site in the studies.
