HRCT findings at the time of diagnosis of AIPF (n=32)

Reticulation score (%)
 Most affected lung27.2±22.322.35.95–75
 Least affected lung10.1±69.60–19.1
Ground glass score (%)
 Most affected lung10.7±11.77.20–64
 Least affected lung2.1±3.770.90–21
Fibrosis score (%)
 Most affected lung39±19.73515–90
 Least affected lung12.3±8120–39
Asymmetry ratio*0.52±0.210.500.24–1
  • * Asymmetry ratio was calculated as (most affected – least affected fibrosis score)/(global fibrosis score) and ranged from 0 to 1.

  • AIPF, asymmetrical idiopathic pulmonary fibrosis; HRCT, high-resolution CT scan.
