Figure 4From: MRI to assess chemoprevention in transgenic adenocarcinoma of mouse prostate (TRAMP) Changes in signal intensity and micro-tumor foci. (A) Changes in T2 signal intensity in seminal vesicles was significantly higher in control animals at 25 weeks, which indicate heterogeneous tissues (involvement of micro-tumor foci) compared to that of treated animals at 25 weeks or of animals at 5 weeks. (B) Multiple tumor foci were observed in seminal vesicles of control animals (a, b, c, d) compared to that of treated animals (e, f). a, b, e are with x10 and c, d, f are with x40 magnifications. Bars in all images represent 100µm.Back to article page
