✦ Synopsis

Using a 21-in. cathode ray tube (CRT) monitor (2048 £ 2560 £ 8 bits), six radiologists interpreted 12 images with interstitial lung disease under six conditions of CRT luminance (50 and 400 cd/m 2 ) and room illuminance (20, 120 and 480 lx), and 10 radiologists interpreted 25 images with pulmonary nodules under nine conditions of CRT luminance (50, 200 and 500 cd/m 2 ) and room illuminance (20, 120 and 480 lx). Observer's performance for interstitial disease was relatively better at 120 lx. Four hundred and eighty lux illuminance with 50 cd/ m 2 CRT luminance, which degraded the detectability of pulmonary nodule signi®cantly (p , 0.05), should be avoided for clinical use.
