Poor accumulation of technetium-99m glucoheptonate in sarcoidosis and other diffuse infiltrative lung diseases as compared with gallium-67 citrate.
Forty-two patients with diffuse infiltrative lung diseases were imaged with Ga-67 citrate and Tc-99m glucoheptonate (GH). Twenty patients had sarcoidosis, six had fibrosis, six had tuberculosis, nine had lung infiltration, and one had pleural empyema. The main difference between Ga-67 and Tc-99m GH was the much greater uptake of Ga-67 in sarcoidosis than that of Tc-99m GH. Fifteen patients with sarcoidosis had positive Ga-67 scans but only six had positive Tc-99m GH scans. The results in other diffuse infiltrative lung diseases were almost equal with Ga-67 and Tc-99m GH. Although Tc-99m GH is less expensive and simpler to use, it is not an adequate substitute for Ga-67 in diffuse infiltrative lung diseases.
