[The use of color Doppler flow imaging in diagnosis and differential diagnosis of some pulmonary masses].
The status of blood supply was examined in twenty-nine patients with pulmonary masses with color doppler flow imaging. The results showed that there are no significant blood signals in 5 benign masses. One patient with pulmonary arterio-venous fistula can be diagnosed. Pulmonary inflammatory pseudotumor and 20 lung cancers have rich blood supply. The peak forward velocity and resistance index between them have obvious difference statistically (P < 0.05, P < 0.01). It is concluded that color doppler can be regarded as an useful and noninvasive method before operation in diagnosing some pulmonary masses.
