表观扩散系数联合纹理特征评估宫颈鳞癌分化程度的价值
Journal of Practical Radiology（2020）
Abstract
目的 探讨ADC联合纹理分析(TA)评估官颈鳞癌(CS(CC)分化程度的价值.方法 对88例经病理证实的CSCC患者行常规MRI及DWI扫描,b值取0 s/mm2、1 000 s/mm2,获取病灶的ADC值.在T2 WI图像上对病灶进行TA,获得病灶的纹理参数.所得结果应用SPSS软件,采用单因素方差分析及LSD,P＜0.05有统计学意义.应用ROC曲线评估有统计学差异的ADC及TA参数的诊断效能.结果 ADC值在低、中分化组及低、高分化组之间均有统计学差异(P＜0.05),在中、高分化组之间无统计学差异(P＞0.05).3组间纹理特征比较,标准差和熵值有统计学差异(P＜0.05).ADC联合TA的诊断效能高于两者单独诊断.结论 ADC联合TA可以提高术前评估CSCC分化程度的效能,为CSCC个性化治疗和预后评价提供客观依据.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
