The T1 relaxation rate changes of 22 patients with metastatic prostate cancer with antiangiogenic therapy are reported. The bone and lymph node lesions were monitored through 4 cycles of therapy. And the observed T1 changes suggest the need for accurate estimation of those if quantitative analyses incorporating T1 vales are to be used for therapy response monitoring.
