Dynamic Contrast Enhanced Ultrasonography (DCE-US)
Early functional evaluation of new treatments in oncology is of major importance. Overall survival rate is the best criterion for assessing treatment, but unfortunately it calls for lengthy follow-up whereas treatment efficacy must be ascertained as soon as possible. The morphological criteria normally used (WHO or RECIST) do not lend themselves easily to new therapies which often induce lesion necrosis without reducing tumor volume.
