Comparison of a Medical-Grade Monitor vs Commercial Off-the-Shelf Display for Mitotic Figure Enumeration and Small Object (Helicobacter pylori) Detection.
American Journal of Clinical Pathology 2018 January 30
Objectives: To examine the performance of a commercial off-the-shelf (COTS) monitor vs a medical-grade (MG) monitor for small object enumeration in standardized digital pathology images.
Methods: Pathologists reviewed 35 melanoma or 35 gastric biopsy images using the MG and COTS displays, with a 2-week washout period. Mitotic figure or Helicobacter pylori burden enumerations were compared with reference values reported by an expert subspecialist pathologist using a light microscope. Subjective evaluations of image color, brightness, and overall quality were also obtained.
Results: There was substantial agreement between the mitotic counts obtained by the evaluating pathologists between monitors and the reference mitotic figure or H pylori burden assessments. Six of the nine evaluating pathologists subjectively evaluated the monitors as substantially similar.
Conclusions: These findings are consistent with previous studies demonstrating that color calibration has limited impact on diagnostic accuracy and suggest that noncalibrated displays could be considered for fine assessment tasks.
