PICC导管
PICC置管,是经外周静脉穿刺中心静脉置管,是利用导管从外周手臂的静脉进行穿刺,导管直达靠近心脏的大血管。避免化疗药物与手臂静脉的直接接触,加上大静脉的血液回流较快,可以迅速稀释化疗药物,防止药物对血管的刺激,因此能够有效的保护上肢静脉,减少静脉炎的发生,减轻患者的疼痛,提高患者的生命质量。
PICC导管定位
大多数研究认为,导管尖端最佳位置应位于:上腔静脉的中下1 /3,或上腔静脉与右心房汇合处上方2~4 cm。也有文献报道,PICC 尖端的最佳位置是其X 线位置在第6 ~7胸椎水平。
目前X光胸片正位片,对于定位PICC导管位置,是一种常用、简单有效的方法。如果PICC导管在胸片定位上人为识别错误,会给患者后续治疗带来隐患。因此有学者提出使用深度学习来辅助医护人员在胸片对PICC导管进行定位。
以下两篇文章都是基于对PICC导管进行分割,然后再进一步定位。可见准确无误分割出PICC管道对于定位是很重要。
《Detection of peripherally inserted central catheter (PICC) in chest X-ray images: A multi-task deep learning model》
《A Deep-Learning System for Fully-Automated Peripherally Inserted Central Catheter (PICC) Tip Detection》
因此本项目通过标注118张数据,使用两种方法,第一种训练前把数据先固定分切成训练集和测试集。第二种使用5折交叉训练模型。结果融合5折交叉模型的分割结果更优。
图下是5折,5个模型不同的预测结果
图下经过5折交叉模型融合之后,PICC的预测结果比每一折的结果都要好
