粘连性与植入性胎盘植入的MRI征象分析
Zhejiang Clinical Medical Journal（2021）
Abstract
目的 分析粘连性胎盘(PA)和植入性胎盘(PI)植入的MRI特征,探讨其在产前诊断中的应用.方法 选取2016年1月至2020年5月胎盘植入患者70例,根据胎盘植入类型分为PA组粘连性胎盘植入37例,PI组植入性胎盘植入33例.回顾性分析其临床资料及MRI征象.结果 PA组和PI组的术中出血量及有无子宫全切差异有统计学意义(P<0.05),年龄、剖宫产次、流产次数、产前阴道流血、腹痛、前置胎盘差异无统计学意义(P>0.05);MRI征象中胎盘内T2低信号带、胎盘局限性隆起、胎盘后低信号带中断/消失差异有统计学意义(P<0.05),子宫肌层变薄/中断、膀胱壁毛糙/中断、胎盘局部外生性团块、胎盘床异生血管差异无统计学意义(P>0.05).结论 胎盘内T2低信号带、胎盘局限性隆起、胎盘后低信号带中断/消失有助于产前鉴别胎盘植入类型.

- 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
