Response assessment: What we would
expect
•
T2: Reduced conspicuity
–
Loss of tumor mass
–
Reduced water content of peripheral zone
•
DCE MRI: Reduction of CM uptake
–
Decreased angiogenesis
–
... But counteracted by inflammation
•
DWI: Reduced conspicuity, increase in
ADC
–
Loss of cellular density
–
... But contaminated by T2 effects
