四维彩色多普勒血流成像技术在诊断胎儿主动脉弓及其分支异常中的应用价值分析
Chinese Remedies & Clinics（2020）
Abstract
目的 探讨四维彩色多普勒血流成像技术在诊断胎儿主动脉弓及其分支异常中的应用价值.方法 选取2017年3月至2019年6月在我院进行产前胎儿畸形筛查的孕妇107例为研究对象,均行四维彩色多普勒血流成像技术,并以随访结果为标准,统计其诊断结果及价值.结果 经随访发现,107例孕妇中发生胎儿主动脉弓及其分支异常67例,发生率为63％;四维彩色多普勒血流成像技术诊断胎儿主动脉弓及其分支异常的准确度为89％,特异度为80％,敏感度为94％,阳性预测值为97％,阴性预测值为76％;四维彩色多普勒血流成像诊断主动脉狭窄、主动脉弓离断及血管环畸形的检出率与随访结果对比,差异无统计学意义(P>0.05).结论 四维彩色多普勒血流成像诊断胎儿主动脉弓及其分支异常的诊断价值较高,有助于产前筛查胎儿畸形,为干预措施的制定提供依据.

- 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
