A 2 ranking is considered a medium quality scan. 3 ranking is a low quality scan.3 is the lowest ranking a scan can receive and still be considered a passing scan. Anything below 3 would be a failure for quality. Choosing MPRAGES: For scans ranked 2 and 3 the scan ranked 2 (whatever is the lower ranking of the two) should always be the "preferred/chosen"MPRAGE. If the rankings are tied in ranking the QC-er would chose the"sharper of the two". If the two scans are identical the first MPRAGE was always chosen. The preferred scan is indicated by the LONIUID field in the MRIMPPRO table.
