[Evaluation of the blood flow in tumors before and after irradiation with color Doppler flow imaging].
The blood flow in tumors of three patients with lung cancer, cancer in oral cavity and metastatic lymphnode was respectively evaluated before and after irradiation with color Doppler flow imaging. The arterial pulsating flow in lung cancer disappeared after 30 Gy irradiation and that in cancer of oral cavity disappeared after 15 Gy irradiation with intraarterial infusion chemotherapy. But the arterial pulsating flow in metastatic lymphnode was detected during irradiation and disappeared after 40 days post- irradiation. Therefore color Doppler flow imaging seemed to be useful for evaluation of the blood flow in tumors before and after irradiation.
