[Evaluation of the blood flow in lung disease with color Doppler flow imaging].

Blood flow within the lesions was evaluated in 6 patients of lung cancer and in 4 patients with pulmonary tuberculosis with color Doppler flow imaging. Three different signal types were noted: pulsatile signal was detected in all patients with lung cancer and in 2 patients with pulmonary tuberculosis, continuous signal was only detected in 3 patients with lung cancer, triphasic signal was detected in 4 patients with pulmonary tuberculosis and in 2 patients with lung cancer. It was seemed to be that triphasic signal was blood flow signal in peripheral vessel of pulmonary vein and color Doppler flow imaging was useful for evaluation of blood flow patterns in lung disease.
