FIGURE 2

The longitudinal evaluation of tumor in one animal is shown on T2w RARE images (A) and on elastograms of viscoelastic modulus (in kPa; B). Borders of the hyperintense tumor in the T2w scans are circumscribed in weeks 2 and 3 (A, arrowheads) but are harder to delineate in week 4. The mass effect is significant in week 4 with midline shift and occlusive hydrocephalus (A, asterisk in ballooned left ventricle). The tumor is easily detectable on elastograms (B) and values for viscoelastic modulus (C), shear wave speed (D) and phase angle (E) decrease in tumors (black dots) significantly over time compared to healthy tissue (white dots). Mean and SD are shown.
