The goal of this clinical trial is to develop and verify the auxiliary role of the artificial intelligence system in mediastinal 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 integrity and efficiency of the mediastinum scanning for the ultrasound endoscopist. Participants will undergo mediastinal EUS with or without the assistance of the artificial intelligence system.
1. Age ≥18 years old, <80 years old 2.Patients who need endoscopic ultrasonography; 3. Agree to participate in this study and sign the informed consent form.
Poor physical condition, including hemoglobin ≤8.0g/dl, severe cardiopulmonary insufficiency, etc.
Anesthesia assessment failed
Pregnancy or breastfeeding
In the acute stage of chemical and corrosive injury, it is very easy to cause perforation
Parallel
AI system
DevicePatients will undergo EUS examination with the assistance of AI system.
Accuracy
The number of correctly classified images divided by the total number of images.
The completeness for standard station scanning
This was calculated as the number of stations successfully scanned divided by the total number of stations that should have been scanned.
Cohen's kappa coefficient
This data is to evaluate the agreement between the model and the endoscopists.
The completeness for standard stations and anatomical landmarks per individual
The completeness of stations and anatomic landmarks of endoscopic ultrasonography by different endoscopists in the AI system assisted group and the control group were compared.
The completeness of anatomical landmarks
It calculated as the number of anatomical structures successfully scanned divided by the total number of structures that should have been scanned
Operation time
In addition to puncture, elastography, and ultrasound enhancement to observe the lesion or treatment, it can also be used to observe the time of the mediastinum.
