Clinical Research on a Novel Deep-learning Based System in Pancreatic Endoscopic Ultrasound Scanning
Study Details
Study Description
Brief Summary
The goal of this clinical trial is to develop and verify the auxiliary role of the artificial intelligence system in pancreatic ultrasound endoscopic scanning.The main questions it aims to answer are as follows: 1.The comparison of the image recognition accuracy between the artificial intelligence system and the ultrasound endoscopist; 2. Whether the artificial intelligence system can improve the efficiency of the pancreatic scanning for the ultrasound endoscopist. Participants will undergo pancreatic EUS with or without the assistance of the artificial intelligence system.

Detailed Description
In this study, a total of 200 cases of pancreatic endoscopic ultrasound scanning videos and images will be collected. First of all, an artificial intelligence system based on deep learning for the navigation and quality control of pancreatic endoscopic ultrasonography will be established. Secondly, the artificial intelligence system will be used to identify the site and anatomical structure of the pancreatic ultrasound endoscopy, and the results of the artificial intelligence system's station recognition will be compared with the results of the endoscopist's station recognition. Finally, compare the image recognition speed, image recognition accuracy and precision of endoscopists with and without the assistance of artificial intelligence system.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: AI-assisted group Subjects will undergo EUS examination with the assistance of artificial intelligence(AI) system. |
Device: artificial intelligence system
Patients will undergo EUS examination with the assistance of artificial intelligence(AI) system.
|
| No Intervention: Non-assisted group Subjects will undergo EUS examination without the assistance of artificial intelligence(AI) system. |
Outcome Measures
Primary Outcome Measures
- Accuracy [1 year]
The number of correctly classified images divided by the total number of images.
- intersection over union (IoU) [1 year]
It was defined as the relative area of overlap between the predicted bounding box(A) and the ground-truth(B) bounding box.
- Precision [1 year]
When the IoU was greater than the threshold, the prediction was true positive(TP); when the IoU was less than the threshold, the prediction was false positive(FP). When the model segmentation area was equal to 0, it was false negative(FN).Precision=TP/(TP+FP)
- Recall [1 year]
Recall=TP/(TP+FN)
- Dice [1 year]
Dice=2TP/(2TP+FP+FN)
Secondary Outcome Measures
- Cohen's kappa coefficient. [1 year]
This data is to evaluate the agreement between the model and the endoscopists.
