title: [Analysis of 123I IMP retention in the lung and application to the diagnosis of lung disease].
abstract: The movement of N-isopropyl-p[123I] iodoamphetamine (I-123 IMP) in the lungs was studied. The half time of I-123 IMP release (T 1/2) was delayed in the fibrosis and the sarcoidosis. There was a relation between the prolongation of T 1/2 and the radiographic finding. It was considered that T 1/2 was useful for the objective estimation of the change in the lungs. The adsorption of I-123 IMP to the alveolar cells was much higher than to the circulating leukocytes. It was considered that the accumulation and retention of I-123 IMP in the lungs had relation to the alveolar cells.
