[en] In this paper we report our recent experience indicating usefulness of ⁶⁷Ga-citrate scintigraphy in 4 cases with inflammatory pulmonary diseases. These cases showed abnormal pulmonary ⁶⁷Ga uptake with normal chest radiographs. The first case with malignant lymphoma and the second one with lung cancer suffered from pulmonary infection following secondary immuno-insufficiency due to radiotherapy and chemotherapy. Pneumocystis carinii was suspected as causative agent in the first case, and gram negative bacilli in the second case. The third case with lung cancer developed radiation pneumonia after radiotherapy. The fourth case with acute bronchitis developed drug induced interstitial pneumonia presumably due to minocycline administration. It is concluded that ⁶⁷Ga-citrate scintigraphy is more sensitive for early detection of interstitial pneumonia than routine chest radiography. (author)
