Abstract

Purpose: The purpose of this study is to compare interpretation efficiency of radiologists reading radiographs on 6 megapixel (MP) versus 12 MP monitors.

Approach: Our method compares two sets of monitors in two phases: in phase I, radiologists interpreted using a 6 MP, 30.4 in. (Barco Coronis Fusion) and in phase II, a 12 MP, 30.9 in. (Barco Nio Fusion). Nine chest and three musculoskeletal radiologists each batch interpreted an average of 115 radiographs in phase I and 115 radiographs in phase II as a part of routine clinical work. Radiologists were blinded to monitor resolution.

Results: Interpretation times per radiograph were noted from dictation logs. Interpretation time was significantly decreased utilizing a 12 MP monitor by 6.88 s ( $p = 0.002$ ) and 6.76 s (8.7%) ( $p < 0.001$ ) for chest radiographs only and combined chest and musculoskeletal radiographs, respectively. When evaluating musculoskeletal radiographs alone, the improvement in reading times with 12 MP monitor was 6.76 s, however, this difference was not statistically significant ( $p = 0.111$ ). Interpretation of radiographs on 12 MP monitors was 8.7% faster than on 6 MP monitors.

Conclusion: Higher resolution diagnostic displays can enable radiologists to interpret radiographs more efficiently.

X 光片的解读时间效率：标准 6 MP 和 12 MP 高分辨率显示屏的对比研究。

目的：本研究的目的是比较放射科医生在 600 万像素和 1200 万像素显示器上阅读 X 光片的判读效率：我们的方法分两个阶段对两套监视器进行比较：在第一阶段，放射医师使用 6 兆像素、30.4 英寸（Barco Coronis Fusion）监视器进行判读；在第二阶段，使用 12 兆像素、30.9 英寸（Barco Nio Fusion）监视器进行判读。作为常规临床工作的一部分，9 名胸部放射科医生和 3 名肌肉骨骼放射科医生平均每批在第一阶段和第二阶段分别解读了 115 张射线照片。放射科医生在监测分辨率方面是盲人：结果：根据口述日志记录了每张 X 光片的判读时间。使用 12 MP 监视器后，仅胸部 X 光片的判读时间明显缩短了 6.88 秒（p = 0.002），而仅胸部和肌肉骨骼联合 X 光片的判读时间则分别缩短了 6.76 秒（8.7%）（p 0.001）。在单独评估肌肉骨骼 X 光片时，使用 12 MP 监视器的读片时间缩短了 6.76 秒，但这一差异没有统计学意义（P = 0.111）。使用 1200 万像素显示器判读射线照片比使用 600 万像素显示器快 8.7%：结论：更高分辨率的诊断显示器能让放射医师更高效地解读射线照片。
