Diagnostic Concordance Using Japan Narrow-band Imaging Expert Team Classification for Diagnosing Colorectal Neoplasms: A Web-based Diagnostic Concordance Study.

ABSTRACT:

Objectives

The Japan Narrow-band Imaging Expert Team (JNET) classification is widely used for magnified endoscopic diagnosis of colorectal neoplasms. However, its diagnostic concordance, particularly among the core members who contributed to its development, has not been sufficiently evaluated. Therefore, this study aimed to assess the diagnostic concordance of the JNET classification among JNET core members using a web-based image interpretation test.

Methods

A total of 27 JNET core members performed a web-based static image reading test in two separate sessions. Each image was classified according to the JNET criteria, and the diagnostic concordance rate (DCR) was analyzed. Cases were categorized as having high (≥80% consensus), moderate (70%-79% consensus), or low (<70% c
