Sequential measures on HRCT of the lung. A forty-three old woman intentionally ingested on paraquat in a suicide attempt. She presented to the hospital within 3 hr of ingestion. Serum paraquat level was 2.63 µg/mL. Note that the area of the lung lesion was not expanded in the sequential HRCT. The process of lung fibrosis completes by one month.
