声触诊组织量化成像评估急性闭合性不完全断裂跟腱弹性
Chinese Journal of Medical Imaging Technology（2019）
Abstract
目的 探讨声触诊组织量化成像(VTIQ)技术评价中青年男性急性闭合性不完全跟腱断裂开放性修复术前及术后跟腱弹性特征的价值.方法 选取32例中青年男性急性闭合性不完全跟腱断裂患者,采用VTIQ获得双侧跟腱速度模式图,于中立位测量跟腱远段(跟腱跟骨附着处以上5 cm)、中段(跟腱跟骨附着处以上＞5～10 cm)及近段(跟腱跟骨附着处以上＞10 cm至肌-腱结合处)SWV值,比较术前1周、术后12周和24周两侧跟腱对应节段SWV值.结果 术前1周息侧跟腱SWV值均低于健侧对应节段(P均＜0.001),且双侧跟腱远段SWV值均高于同侧中段及近段(P均＜0.01);术后12周患侧跟腱中段及远段较健侧对应节段SWV降低(P均＜0.001);术后24周患侧跟腱远段较健侧远段SWV值降低(P＜0.001).患侧跟腱各段SWV值随时间延长而逐渐增高,两两时间点比较差异有统计学意义(P均＜0.01).结论 VTIQ可量化评价急性闭合性不完全跟腱断裂术前及术后跟腱弹性;术后可采用VTIQ为跟腱各节段弹性提供客观评估指标.

- 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
