应用MSCT图像后处理技术鉴定肋骨骨折1例

A Case of Application of MSCT Image Post-Processing Technology in the Identification of a Rib Fracture

摘要: 肋骨骨折是较常见的胸部损伤，肋骨骨折数量是决定损伤程度和伤残等级的重要指标。螺旋CT (MSCT)检查是目前临床公认诊断肋骨骨折的首选方法。在鉴定工作中，肋骨骨折的数量前后不一致，临床报告与法医阅片结果不符的情况时有发生，不仅困扰法医，也是导致重新鉴定，甚至多次鉴定的原因。笔者以所检案件为例，应用MSCT图像后处理技术对原始影像数据进行图像重组，并动态观察肋骨前后变化，探讨如何提高肋骨骨折的CT应用价值和诊断效率，以期为法医鉴定提供借鉴。

Abstract: Rib fractures are a common chest injury, and the number of rib fractures is an important indicator of the degree of injury and disability level. Spiral CT (MSCT) is currently the clinically recognized first-line diagnostic tool for rib fractures. In clinical cases, inconsistencies in the number of rib fractures and discrepancies between clinical reports and forensic imaging results frequently occur, not only troubling forensic doctors but also leading to re-identification and even multiple identifications. This paper uses a case as an example, applying MSCT image post-processing technology to reconstruct images from the original image data and dynamically observing changes in the ribs before and after the fracture, exploring how to improve the application value and diagnostic efficiency of CT in rib fracture identification, aiming to provide a reference for forensic identification.
