Clinical efficacy of color Doppler flow imaging in the treatment of malignant trophobiastic tumors

Objective To detect the valne of color Doppler flow imaging (CDFI) in the treatment of malignant trophobiastic tumors. Methods Thirty patients were examined before and after chemotherapy. The changes of blood flow velocitvy and its resistance index were measured by CDFI. Results In CDFI, before chemotherapy, a colorful and rich low resistance flow spectrum was observed in the tumor area. After chemotherapy, the blood flow message decreased significantly ( P < 0.05 ). Conclusion CDFI is useful for obs...
