肌骨肿瘤网络图像检索：返回的MR序列是否正确
本研究系统评估了通用搜索引擎对16种良恶性肌骨肿瘤MR图像的检索质量，重点分析T1W、T2W、增强、DWI及反相位图像。结果显示常规序列检索正确率较高，高级序列检索正确率偏低。
要点
- 常规序列T1W、T2W及增强图像网络检索可靠性较高。
- DWI与反相位图像网络检索正确率偏低，阅片参考时需谨慎。
- 评判一致性中等至较强，但高级序列图像质量仍不稳定。
核心结论
- 通用搜索引擎检索常规MRI序列的肌骨肿瘤图像时返回有用结果，但检索高级MR图像时表现欠佳。
研究设计与样本
- 系统性网络检索研究，纳入16种良恶性肌骨肿瘤，针对T1W、T2W、增强、DWI及反相位图像进行检索评估。
- 每种检索取前五张图像，采用5分制评分系统评价图像质量与临床相关性。
- 采用Fleiss Kappa统计评估评判者间一致性。
关键影像表现/征象
- T1W图像检索中88%的病变前五位结果返回了正确序列。
- T2W图像检索中100%的病变前五位结果返回了正确序列。
- 增强图像检索中100%的病变前五位结果返回了正确序列。
- DWI检索中63%的病变前五位结果返回了正确序列。
- 反相位图像检索中25%的病变前五位结果返回了正确序列。
诊断标准与关键数值
- T1W检索正确序列比例88%，T2W为100%，增强为100%，DWI为63%，反相位为25%。
- 二元有用的图像判定Fleiss Kappa为0.72，五分类判定Fleiss Kappa为0.48。
临床应用与阅片要点
- 常规序列网络图像可作为肌骨肿瘤阅片参考，高级序列图像不宜单独依赖。
- 需要注意网络图像来源未经标准化质控，序列标注可能存在错误或混淆。
局限性
- 未报告纳入病例的具体病理分布及图像原始来源的质量控制情况。
- 仅评估单一通用搜索引擎，未比较不同搜索平台的检索表现。

AIM: When radiologists encounter an unfamiliar musculoskeletal neoplasm on conventional and advanced MR images, they now have an option to search the internet for MRI image examples. The purpose of this project was to systematically evaluate the quality of images returned by a widely used general search engine.
MATERIALS AND METHODS: Systematic internet searches were conducted for 16 benign and malignant musculoskeletal neoplasms, focusing on T1-weighted (T1W), T2-weighted (T2W), contrast-enhanced, diffusion-weighted (DWI), and out-of-phase MR images. The top five images from each search were evaluated for image quality and clinical relevance using a 5-point scoring key.
RESULTS: General internet engine returned correct sequence among the top five results for 88% of lesions when searched for T1W images, 100% for T2W images, 100% for contrast-enhanced images, 63% for DWI, and 25% for out-of-phase images. Fleiss Kappa statistic demonstrated substantial agreement (Kappa = 0.72) for binary "useful" vs "not useful" image designation, and moderate agreement (Kappa = 0.48) for all five categories.
CONCLUSION: The general internet search engine returned useful results when searching for conventional MRI sequences but performed sub-optimally when searching for advanced MR image examples.
