Performance evaluation of CAD software to support the detection of chronic fibrosing interstitial lung diseases by chest simple X-ray imaging

Not Applicable

• Conditions: Chronic fibrosing interstitial lung diseases

• Registration Number: JPRN-jRCT1032220090
• Lead Sponsor: Honda Seiwa

Brief Summary

This study showed that this program is useful as a fibrotic ILD detection support program for non-specialists. In particular, this program was thought to be useful for preventing oversight of fibrotic ILD by primary care physicians. Based on the results of the darkening rate and improvement rate, we believe that the benefit of improving interpretation results by using this program in combination is greater than the risk of misdiagnosis.

Primary Outcome Measures

Name	Time	Method
A paired t-test is performed on the AUC in the ROC curve with and without CAD based on the reading judgment result of a non-specialist, and a significant improvement with CAD is examined.
