Additional file 1 of Detecting low blood concentrations in joints using T1 and T2 mapping at 1.5, 3, and 7 T: an in vitro study

Additional file 1: Figure S1. Detailed description of the position of the samples in the phatom in the different batches scanned. Percentages correspond to the blood percentage in the sample. a) First batch scanned at all field strenghts. b) Second batch scanned at all field strengths. c) Third batch scanned at 3T. Figure S2. (A) Signal intensity in the ROI vs IR delays for the 0% blood tube at 3T: the experimental data are indicated with blue ● and the fitting with a red line. (B) Analysis of the residuals: each ● represents the residual of each experimental data point from the one predicted with the fitting. The mean of the residual is also reported as dotted line. Figure S3. T2 mapping at 1.5T with different echo spacing on dependence on the blood concentration. Figure S4. T2 mapping at 1.5T (A) and 3 T (B) with a multi-slice accelerated scans and single slice non accelerated scans.
