[Mercury dichloride in lung pathology. Study of 241 patients]

In 241 patients suffering from various of lung pathology and subjected to lung scanning with mercury bichloride (Hg 197), it was found that 90% of the neoplastic masses pick up the isotope in significant fashion; 40% of the masses of other nature also pick up the compound. This results means that scanning with radioactive mercury bichloride is of little diagnostic usefulness.
