Pharmaceutical composition for inhalation administration to labeling pulmonary nodules comprising fluorescent contrast agent as an active ingredient

摘要

The present invention relates to a method for providing information on lung tumor determination through inhalation of a fluorescent contrast agent, and more particularly, to a method of inhaling a small amount of indocyanine green, and the fluorescent contrast agent is distributed throughout the body through conventional intravenous injection There is no problem, and when comparing the cancer screening efficacy of the inhaled fluorescent contrast agent and the intravenously injected fluorescent contrast agent, the cancer screening efficacy through the inhalation of the fluorescent contrast agent is significantly higher and higher than that of the intravenous injection.
