■在法医调查中使用放射学方法正在迅速成为传统尸检的替代方法。这里,我们介绍西西里和卡拉布里亚法医部门在过去五年中的经验,强调PMCT在涉及枪伤受害者的病例中支持尸检的应用。
■从2020年1月至2024年3月,30名死于枪伤的尸体接受了全身PMCT检查,随后进行了尸检。检查包括多平面和3D重建。为每个受试者收集的数据包括性别,年龄,死亡模式,类型的武器,射击次数,身体部位受影响,以及保留子弹的存在。由两名放射科医生和两名法医组成的团队评估了图像,并将其与尸检结果进行了比较。
■PMCT和3D重建能够评估进入伤口,骨折边缘,损伤部位,碎片,和解剖学轨迹。将PMCT的结果与尸检结果在进入伤口方面进行了比较,伤口通道,异物,器官和骨骼损伤,和死亡原因。PMCT在确定所有病例的死亡原因方面与尸检结果一致。速度,非侵入性,以及操纵和重建数据的能力使PMCT成为支持法医调查和尸检的理想技术。PMCT对于准确识别致命伤口和确定死亡原因非常可靠。它擅长跟踪伤口路径,区分入口和出口伤口,定位保留的子弹,并检测弹道成分的碎裂和分散。
UNASSIGNED: The use of radiological approaches in forensic investigations is rapidly emerging as an alternative to traditional autopsies. Here, we present the experience of the Sicilian and Calabrian forensic medical departments over the past five years, highlighting the application of PMCT to support autopsies in cases involving gunshot wound victims.
UNASSIGNED: From January 2020 to March 2024, thirty cadavers who died from gunshot wounds underwent total body PMCT examinations followed by autopsies. The examinations included multi-planar and 3D reconstructions. Data collected for each subject included gender, age, mode of death, type of weapon, number of shots, body sites affected, and presence of retained bullets. A team of two radiologists and two forensic physicians evaluated the images and compared them with the autopsy findings.
UNASSIGNED: PMCT and 3D reconstruction enabled evaluation of entry wounds, fracture margins, injury sites, fragments, and anatomical trajectories. The results from PMCT were compared with autopsy findings in terms of entry wounds, wound channels, foreign bodies, organ and skeletal injuries, and causes of death. PMCT showed concordance with autopsy findings in determining the cause of death in all cases. The speed, non-invasiveness, and ability to manipulate and reconstruct data make PMCT an ideal technique for supporting forensic investigations and autopsies. PMCT is highly reliable for accurately identifying lethal wounds and determining the cause of death. It excels at tracking wound paths, distinguishing entrance and exit wounds, locating retained bullets, and detecting fragmentation and dispersion of ballistic components.
