개요

PENGWIN challenge는 MICCAI 2024 위성 행사로 개최되어, CT 및 X-ray 영상에서 골반 골절 파편 분할 자동화를 위한 최첨단 알고리즘의 성능을 벤치마킹하는 것을 목표로 했습니다. 다양한 임상 센터에서 수집한 150개의 CT 스캔과 DeepDRR 방법을 사용하여 생성된 대량의 시뮬레이션 X-ray 영상 데이터셋을 사용했습니다. 전 세계 16개 팀의 최종 제출물은 엄격한 다중 지표 테스트 방식으로 평가되었으며, CT 알고리즘의 최고 성능은 평균 파편별 IoU 0.930을 달성했지만, X-ray 알고리즘의 최고 성능은 IoU 0.774에 그쳐 X-ray 영상에서의 어려움을 보여주었습니다. 알고리즘 설계의 방법론적 다양성과 불완전 골절에서의 파편 정의의 불확실성이 드러났으며, 이는 인간의 의사결정을 통합하는 대화형 분할 접근 방식이 모델의 신뢰성과 임상 적용성을 향상시키는 데 필수적임을 시사합니다.

시사점, 한계점

•

시사점:

◦

◦

X-ray 영상 분할의 어려움과 향상의 필요성을 강조 (평균 IoU 0.774).

◦

다양한 알고리즘 설계 방법론과 인스턴스 표현 방식(primary-secondary 분류 vs. boundary-core 분리) 존재 확인.

•

한계점:

◦

X-ray 영상에서의 낮은 정확도.

◦

불완전 골절에서의 파편 정의의 모호성 및 불확실성.

◦

모델의 신뢰성과 임상 적용성 향상을 위해 인간의 개입이 필요함을 시사.
