Abstract

Background/aim: Costal cartilage fractures are associated with poor prognosis in patients with blunt chest trauma. A Computer-Aided Detection (CAD) system for detecting rib fractures has been used in practice, but it is unclear whether this system recognizes costal cartilage fractures. This study investigated whether the CAD system for rib fracture can detect costal cartilage fractures.

Patients and methods: A total of 89 patients with costal cartilage fractures from participating hospitals over an 18-year period were included in the study. The presence of a costal cartilage fracture was determined by three radiologists. We reviewed fracture location, cartilage calcification, dislocation, and callus formation. The percentage of agreement between the radiologists and the CAD system (Rib fracture CAD, Fujifilm Medical Co., Ltd) was assessed.

Results: We detected 246 costal cartilage fractures in 89 patients. The costal cartilage of rib 7 was injured most frequently. Costal cartilage fractures were categorized as either mid-chondral, costochondral, or chondro-sternal. The CAD system detected 33 lesions; 16 were consistent with the costal cartilage fractures determined by the radiologists (costochondral junction 13, mid-chondral 2, chondro-sternal 1).

Conclusion: The CAD system for rib fracture can detect costal cartilage fractures at the costochondral junction but is not sufficiently sensitive to detect costal cartilage fractures without calcification. The CAD system for rib fracture needs further development before it can be used to detect rib cartilage fractures.

肋骨骨折计算机辅助检测系统在CT图像上的检测。

背景/目的：钝性胸外伤患者的肋软骨骨折与预后不良相关。计算机辅助检测（CAD）系统用于检测肋骨骨折已在实践中使用，但尚不清楚该系统是否识别肋软骨骨折。本研究探讨肋骨骨折CAD系统能否检测肋软骨骨折。患者和方法：本研究共纳入了18年间89例来自各医院的肋软骨骨折患者。肋软骨骨折的存在是由三位放射科医生确定的。我们回顾了骨折位置、软骨钙化、脱位和骨痂形成。评估放射科医师与CAD系统（富士胶片医疗有限公司肋骨骨折CAD）之间的一致性百分比。结果：89例患者共发现246例肋软骨骨折。7肋肋软骨损伤最多。肋软骨骨折分为中软骨、肋软骨或软骨胸骨骨折。CAD系统检测到病变33处；16例与放射科医师诊断的肋软骨骨折一致（肋软骨交界处13例，软骨中2例，软骨胸骨交界处1例）。结论：肋骨折CAD系统可检测肋软骨交界处的肋软骨骨折，但对无钙化肋软骨骨折的检测灵敏度不够。肋骨骨折CAD系统在用于肋软骨骨折检测之前还需要进一步的发展。
