Clinical Research on a Novel Deep-learning Based System in Mediastinal Endoscopic Ultrasound Scanning
March 29, 2023 updated by: The Third Xiangya Hospital of Central South University
Clinical Research on Navigation and Quality Control System of Mediastinal Ultrasound Endoscopy Based on Deep Learning
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 efficiency of the mediastinum scanning for the ultrasound endoscopist.
Participants will undergo mediastinal EUS with or without the assistance of the artificial intelligence system.
Study Overview
Detailed Description
In this study, a total of 200 cases of mediastinal endoscopic ultrasound scanning videos will be collected.
First of all, an artificial intelligence system based on deep learning for the navigation and quality control of mediastinal endoscopic ultrasonography will be established.
Secondly, the artificial intelligence system will be used to identify the site and anatomical structure of the mediastinal ultrasound endoscope, 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.

Description
Inclusion Criteria:
- 1. Age ≥18 years old, <80 years old 2.Patients who need endoscopic ultrasonography of mediastinum; 3. Agree to participate in this study and sign the informed consent form.
Exclusion Criteria:
- Subjects who meet any of the following criteria cannot be selected for this trial:
First. The patient's physical condition does not meet the requirements of conventional endoscopic ultrasonography:
- 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
- Recent acute coronary syndrome or clinically unstable ischemic heart attack
- Heart disease patients with right-to-left shunt, patients with severe pulmonary hypertension (pulmonary artery pressure> 90mmHg),patients with uncontrolled systemic hypertension and patients with adult respiratory distress syndrome.
Second. Disagree to participate in this study.
Third. There are other problems that do not meet the requirements of this research or that affect the results of the research:
- Mediastinal lesions have previously undergone surgery or radiotherapy and chemotherapy;
- Mental illness, drug addiction, inability to express themselves or other diseases that may affect follow-up.
