Quantitative volumetric contrast-enhanced MR imaging assessment technique (qEASL). The left column represents baseline MR imaging, and the right column represents the follow-up MR imaging after TACE. (a and b) The semiautomated tumor segmentation on a representative contrast-enhanced T1-weighted MR sequence at the arterial phase. (c and d) The corresponding volume of the segmented tumor in a 3D rendering. (e and f) The T1-weighted MR sequence before contrast administration to demonstrate baseline background signal intensity of the tumors. (g and h) The qEASL color maps of the tumor on the subtracted MR imaging scan [the scan before contrast material (E and F) was subtracted from the arterial phase scan (a and b) to remove any background signal intensity]. Color maps: red represents maximum enhancement and blue represents no enhancement, normalized by the ROI. Green box: 3D ROI used as the reference background of image intensity.
