Use of gallium scanning in predicting resolution of Legionnaires' pneumonia.
The value of Ga-67 scanning to detect acute infectious lung disease has been described. We present a patient who apparently improved both clinically and radiographically after acute Legionnaires' pneumonia. Five months later a relapse developed. During his relapse the pulmonary uptake of Ga-67 and the appearance of chest x-rays were disparate. We suggest that pulmonary Ga-67 uptake may be a more sensitive indicator of the resolution of pneumonia than is chest radiography. Therapeutic success may be assumed when pulmonary Ga-67 uptake is absent.
