Table 3.

Precision errors of quantitative parameters shown in Table 2. The time period between repeated measurements is indicated in column ‘Period’. ST: short term (same day); the digit after ST denotes the number of total acquisitions;/repos: subjects were repositioned between acquisitions. Depending on publication, precision errors are either reported as root mean square coefficient of variation (CV_RMS) in % [177] or as intraclass correlation coefficients (ICC). IF: intra fascia; PDFF: proton density fat fraction; wb: whole body.
