Figure 2.

Patient diagnosed with tumor recurrence at starting time point (a,c,e), and final time point taken before diagnosis of lesion etiology (b,d,f,g). Post‐contrast T ₁ ‐weighted MR images (a,b) are used to estimate observed tumor cellularity (c,d) and the model is fit to estimate tumor cellularity (e,f). FLAIR imaging at the time point prior to diagnosis (g) is compared to estimated mechanical stress field (h) at the final time point. [Color figure can be viewed at wileyonlinelibrary.com]
