Abstract

This article discusses studies and real-world experiences related to the clinical application of artificial intelligence-based computer-aided detection (AI-CAD) software (LuCAS-plus, Monitor Corporation) in detecting pulmonary nodules. During clinical trials for lung cancer screening, AI-CAD exhibited performance comparable to that of medical professionals in terms of sensitivity and specificity. Studies revealed that applying AI-CAD for diagnosing pulmonary metastases led to high detection rates. The use of a nodule matching algorithm in diagnosing pulmonary metastases significantly reduced false non-metastasis results. In clinical settings, implementing AI-CAD enhanced the efficiency of pulmonary nodule detection, saving time and effort during CT reading. Overall, AI-CAD is expected to offer substantial support for lung cancer screening and the interpretation of chest CT scans for malignant tumor surveillance.

본 종설에서는 모니터코퍼레이션(주)의 폐결절 검출을 위한 인공지능 기반 컴퓨터 보조 병변 검출(artificial intelligence-based computer-aided detection; 이하 AI-CAD) 소프트웨어 LuCAS-plus의 임상적 활용에 관한 연구와 실제 사용 경험을 기술하였다. AI-CAD의 폐암 검진에 대한 임상시험에서는 민감도와 특이도 측면에서 의료진의 판단과 비슷한 수준의 성능을 보였으며, 악성 종양의 폐전이 진단에 적용한 실증연구에서도 높은 검출 성능을 보여주었다. 또한 폐전이 진단에서 AI-CAD와 결절 매칭 알고리즘을 함께 사용할 경우 위양성 결과를 유의하게 감소시킬 수 있었다. 실제 판독에서도 AI-CAD를 적용함으로써 흉부 CT 판독의 정확성을 향상시키고, 판독에 드는 시간과 노력을 절약할 수 있었다. 종합하면, 폐결절 검출 AI-CAD는 폐암 검진과 악성 종양 경과 관찰 흉부 CT 판독에 유의한 도움을 줄 것으로 기대된다.
