Interpretation time efficiency with radiographs: a comparison study between standard 6 and 12 MP high-resolution...

Area of Science:

• Medical Imaging
• Radiology
• Human-Computer Interaction

Background:

• Radiograph interpretation is critical for medical diagnosis.
• Monitor resolution can impact diagnostic efficiency.
• Previous studies have not conclusively determined the impact of monitor resolution on radiograph interpretation times.

Purpose of the Study:

• To compare the interpretation efficiency of radiologists when using 6 megapixel (MP) versus 12 MP monitors for reading radiographs.
• To quantify differences in interpretation times between the two monitor resolutions.

Main Methods:

• A comparative study involving nine chest and three musculoskeletal radiologists.
• Radiologists interpreted radiographs in two phases: Phase I on 6 MP monitors and Phase II on 12 MP monitors.
• Interpretation times were recorded from dictation logs during routine clinical work, with radiologists blinded to monitor resolution.

Main Results:

• Interpretation time per radiograph was significantly decreased by 8.7% when using 12 MP monitors compared to 6 MP monitors.
• A statistically significant reduction of 6.76 seconds in interpretation time was observed for combined chest and musculoskeletal radiographs.
• While a trend towards faster interpretation was noted for musculoskeletal radiographs alone, the difference was not statistically significant.

Conclusions:

• Higher resolution diagnostic displays, such as 12 MP monitors, can enhance radiologist interpretation efficiency.
• The findings suggest that upgrading to higher resolution monitors may lead to improved workflow and potentially faster diagnoses.
