Comparison of performance of computer display monitors for radiological diagnosis; “diagnostic” high brightness monochrome LCD, 3MP vs “clinical review” colour LCD, 2MP

A study to compare performance of the following display monitors for application as PACS CR diagnostic workstations is described. 1. Diagnostic quality, 3 Mega Pixel, 21 inch monochrome LCD monitors — Planar C3i. 2. Clinical review quality, 2 Mega Pixel, 21 inch colour LCD monitors — Planar PX212. Two sets of seventy radiological studies were presented to four senior radiologists on two occasions, using different displays on each occasion. The clinical condition used for this investigation was to query for the presence of a solitary pulmonary nodule. Receiver Operating Characteristic (ROC) curves were constructed for diagnostic performance for each presentation. Areas under the ROC curves (AUC) for diagnosis using different monitors were compared and the following results obtained: Monochrome AUC=0.813 +/- 0.02, Colour AUC=0.801 +/- 0.021. These results indicate that there is no statistically significant difference in the performance of these monitor types at a 95% confidence level.
