LiverMRDoc reached liver MRI judgments faster in China's review

In the maker's trial that China's CMDE reviewed, judgments on liver MRI took a median of 7.47 minutes with LiverMRDoc, against 9.45 minutes for an expert panel.

  • Not rated an organization

    The time saving was measured on stored images in the maker's pre-market trial, and the report gives no result from use after approval.

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

The system’s part
Not isolated. The trial compared the software's results with target values and its time with that of the expert panel that set the reference standard. The panel and the software group differ in more than the use of the software, so the time saving is not isolated to it. The report says that the product uses deep learning.

Details

AI system

Reported configuration

Release 2.0 (full version 2.0.1.001)

Workflow

The software extracted liver segments from MR images with deep learning and detected suspected focal lesions in them. It listed the cases with suspected lesions, and doctors could add, delete or edit lesions before a text report was made. An expert panel's results served as the reference standard.

Follow-up

Conditions for replication

Patients are adults, and the lesions are 5 mm or larger. Trained doctors use the results as a reference and do not base a clinical decision on the software alone.

Entry details

Sector

Healthcare.

Purpose

Yukun (Beijing) Network Technology built LiverMRDoc to help trained doctors triage suspected focal liver lesions of 5 mm or more in adults on MRI.
