EA PC-UGI helped readers spot more stomach lesions in a trial

In the maker's trial that China's CMDE reviewed, readers using EA PC-UGI reached a lesion-level sensitivity of 85.80% for gastric lesions, against 79.94% alone.

  • Not rated an organization

    Readers worked on stored images in the maker's pre-market trial, and no patient's care depended on the software.

Depth runs from 1, a convenience or time saved, to 5, a life or a livelihood preserved.

Status
Intended benefit.
Evidence

An independent regulatory document supports the benefit.

Compared with

The same readers reading the same images without the software, with pathology as the reference. Measured.

Without the system
79.94%（75.70%，84.18%） lesion-level sensitivity
With it
85.80%（82.45%，89.15%） lesion-level sensitivity
The system’s part
In a fully crossed design, readers read every case with and without the software against pathology, so the gain is attributed to the software. The trial was the maker's own. The report says that the core algorithm is built on deep learning.

Details

AI system

Reported configuration

Release V1

Workflow

The software ran only on frozen images that it recognized as taken inside the digestive tract in a magnifying electronic chromoendoscopy mode. It gave a triage prompt on whether the image showed features of high-grade intraepithelial neoplasia or worse.

Follow-up

Conditions for replication

A doctor has judged that a focal gastric lesion needs magnified electronic chromoendoscopy. Images come from the specified endoscopes and image processors. Trained doctors make the diagnosis and do not base a decision on the prompt alone.

Entry details

Sector

Healthcare.

Purpose

Wuhan EndoAngel Medical Technology built EA PC-UGI to flag features of high-grade intraepithelial neoplasia or worse in frozen, magnified endoscopy images of focal gastric lesions.
