Sequential radiologic and functional pulmonary changes in patients with paraquat intoxication.

The sequential changes of paraquat-induced pulmonary damage were studied using high-resolution computed tomography (HRCT) and pulmonary function tests (PFTs) in long-term follow-up. Among the cohort of 27 patients who had ingested paraquat, the HRCT findings showed a normal (n = 14) and an abnormal group (n = 13). Increased paraquat ingestion in the abnormal group was associated with more rapid and severe pulmonary changes.
