From: Measuring liver fat fraction with complex-based chemical shift MRI: the effect of simplified sampling protocols on accuracy

Fig. 3

Graphs demonstrating the mean % fat fraction, and standard deviation, for each slice through the liver from most caudal (negative slice number) to most cranial (positive slice number). a demonstrates data from an elliptical region of interest (ROI) placed on the right lobe. b demonstrates data from an elliptical ROI placed on the left lobe. c demonstrates the data from freehand whole liver ROIs. Deviations in data points at the cranial-most and caudal-most slices may be caused by movement artefacts and partial volume effects
