[Diagnostic bronchoalveolar lavage in comparison with gallium-67 scintigraphy in the diagnosis and treatment of lung sarcoidosis].

The value of bronchoalveolar lavage (BAL) and Gallium-67-scintigraphy in the diagnosis of sarcoidosis is discussed. Both methods complete themselves and do not compete. Both are good indices for the activity of the disease and for corticoid treatment surveillance. There is not a direct correlation of SACE and Ga-67-scan in active disease. Ga-67-scan is the method preferred to establish the spread of granulomas. This radiological method allows the detection of invisible dissemination in the lungs and other organs. BAL allows a cell differentiation. With this method it is possible to survey the course of the disease and give further informations of the pathogenesis of sarcoidosis.
