ABSTRACT
Objective To evaluate the therapeutic effect of endocrine for prostate cancer with bone metastases with MR diffusion-weighted imaging (DWI). Methods Forty patients with bone metastases from prostate cancer were examined with DWI. Seventeen patients underwent endocrine therapy were recruited as the test group, the other 23 were regarded as the control group. There was no relapse of the metastases according to clinical diagnosis in the test group. DWI sequences were based on steady-state free precession with b value (800 s/mm~2). After identifying the metastasis according to the T1WI and T2WI, ROIs were marked at the metastases, normal muscle, normal bone and bladder on DWI, and the ADC values of the ROIs were calculated respectively. Non-parameter two independent samples test was applicated to compare the ADC values of the metastases between the two groups.Results ADC values of the bone metastases were (1.10±0.50)×10~(-3)mm~2/s in the test group and (1.12±0.30) ×10~-3mm~2/s in the control group (P>0.05).Conclusion MR DWI shows no help in evaluating the therapeutic effect of endocrine for prostate cancer with bone metastases.
