title: Gallium-67 scanning for detection of alveolitis in idiopathic pulmonary fibrosis and sarcoidosis.
abstract: OBJECTIVE
  To investigate 67Gallium scanning for the detection of alveolitis in idiopathic pulmonary fibrosis and sarcoidosis.
  
  
  METHODS
  67Ga scintigraphy was performed in 14 patients with IPF (age: mean +/- s = 58.3 +/- 10.3 years), 13 patients with sarcoidosis (age: mean +/- s = 46.9 +/- 9.0 years) and 11 controls (age: mean +/- s = 44.0 +/- 10.5 years).
  
  
  RESULTS
  Lung/thigh ratio was respectively 3.18 +/- 0.07 in IPF, 3.12 +/- 0.94 in sarcoidosis and 2.11 +/- 0.26 in controls. IPF and sarcoidosis groups had a significantly higher lung/thigh ratio comparing with the control group (P < 0.05). Three patients received 67Ga scanning examination after corticosteroid therapy and the 67Ga uptake decreased.
  
  
  CONCLUSIONS
  The 67Ga scintigraphy is useful in monitoring the activity and extent of alveolitis.
