| 1 | Oleic Acid (OA), A Potential Dual Contrast Agent for Postmortem MR Angiography (PMMRA): A Pilot Study显示文摘Summary:Choosing proper perfusates as contrast agents is an important aspect for postmortem magnetic resonance angiography(PMMRA).However,in this emerging field,the number of suitable kinds of liquid is still very limited.The objective of this research is to compare MR images of oleic acid(OA)with paraffin oil(PO)in vitro and in ex situ animal hearts,in order to evaluate the feasibility to use OA as a novel contrast agent for PMMRA.In vitro,OA,PO and water(control)were introduced into three tubes separately and T,weighted-spin echo(Tw SE)and T2w-SE images were acquired on a 1.5T MR scanner.In the second experiment,0A and PO were injected into left coronary artery(LCA)and left ventricle(LV)of ex situ bovine hearts and their Tw-SE,Tzw-SE,Tw-multipoint Dixon(Tjw-mDixon)and 3DT2w-mDixon images were acquired.The overall results indicate that OA may have a potential to be used as a dual(T and T2 based)contrast agent for PMMRA when proper sequence parameters are utilized.However,as the pilot study was based on limited number of animal hearts,more researches using OA in cadavers are needed to validate our findings. | Zhi-yuan XIA Christine BRUGUIER Fabrice DEDOUIT Silke GRABHERR Marc AUGSBURGER Bei-bei LIU | 2020 | Current Medical Science2020，40，4： | 3 |
| 2 | 溺死虚拟解剖研究进展显示文摘水中尸体并非都是溺死,法医学鉴定的重要任务是区别生前入水和死后入水,明确死亡原因。法医学鉴定实践中,溺死一般依据尸体征象、组织病理学检验和硅藻检验等综合考虑,并需要排除其他死亡原因。虚拟解剖技术的出现为溺死的诊断提供了新的思路。本文综述了国内外近年来对溺死尸体的鼻窦与乳突小房、呼吸道、肺组织、胃肠道和血液等死后的影像学研究成果,探讨虚拟解剖技术在溺死诊断应用上的价值与潜力,并对溺死虚拟解剖的发展方向进行展望。 | 简俊祺 刘宁国 陈忆九 | 2019 | 法医学杂志2019，35，3： | 3 |
| 3 | Postmortem imaging as a complementary tool for the investigation of cardiac death显示文摘In the past 2 decades,modern radiological methods,such as multiple detector computed tomography (MDCT),MDCT-angiography,and cardiac magnetic resonance imaging (MRI)were introduced into postmortem practice for investigation of sudden death (SD),including cases of sudden cardiac death (SCD).In forensic cases,the underlying cause of SD is most frequently cardiovascular with coronary atherosclerotic disease as the leading cause.There are many controversies about the role of postmortem imaging in establishing the cause of death and especially the value of minimally invasive autopsy techniques.This paper discusses the state of the art for postmortem radiological evaluation of the heart compared to classical postmortem examination,especially in cases of SCD.In SCD cases,postmortem CT is helpful to estimate the heart size and to visualize haemopericardium and calcified plaques and valves,as well as to identify and locate cardiovascular devices.Angiographic methods are useful to provide a detailed view of the coronary arteries and to analyse them,especially regarding the extent and location of stenosis and obstruction.In postsurgical cases,it allows verification and documentation of the patency of stents and bypass grafts before opening the body.Postmortem MRI is used to investigate soft tissues such as the myocardium,but images are susceptible to postmortem changes and further work is necessary to increase the understanding of these radiological aspects,especially of the ischemic myocardium.In postsurgery cases,the value of postmortem imaging of the heart is reportedly for the diagnostic and documentation purposes.The implementation of new imaging methods into routine postmortem practice is challenging,as it requires not only an investment in equipment but,more importantly,investment in the expertise of interpreting the images.Once those requirements are implemented,however,they bring great advantages in investigating cases of SCD,as they allow documentation of the body,orientation of sampling for further analyses and gathering of other information that cannot be obtained by conventional autopsy such as a complete visualization of the vascular system using postmortem angiography. | Katarzyna Michaud Pia Genet Sara Sabatasso Silke Grabherr | 2019 | Forensic Sciences Research2019，4，3： | 2 |
| 4 | 数字化与智能化技术在法医病理学鉴定中的研究现状与挑战显示文摘法医病理学是我国司法鉴定活动中的重要组成部分,但其传统技术手段仍存在主观性强、精准性低、特异性差等缺点。近年来,随着计算机技术的不断发展,多学科前沿技术手段开始与人工智能算法相联用,形成了一批可用于涉及损伤、死亡与遗骸识别等的数字化与智能化鉴定手段,为司法实践活动提供了更为科学、客观的鉴定证据。通过总结近年来国内外数字化与智能化技术在法医病理学实践中的最新研究进展,以期为法医病理学学科发展注入新的强劲动力。 | 黄平 张吉 邹冬华 刘宁国 李正东 王金明 秦志强 张建华 | 2023 | 中国司法鉴定2023，，2： | 2 |
| 5 | Forensic imaging:a powerful tool in modern forensic investigation显示文摘Forensic imaging is a non-invasive examination process during the forensic investigation.It is mainly used in forensic pathology as an adjunct to the traditional autopsy.In the past two decades,forensic imaging has been vigorously developed by forensic experts from computed tomography(CT)to multiple augmented techniques through CT and magnetic resonance imaging(MRI).The application field of forensic imaging has also been broadened as its advantages are recognised by more forensic practitioners.In addition to the forensic pathology,this technique has been used in other forensic disciplines,including forensic anthropology,forensic odontology,forensic ballistics and wildlife forensics,etc.This article reviews the development of forensic imaging as the practice and research development in different forensic disciplines based on the relevant literature analysis. | Min Zhang | 2022 | Forensic Sciences Research2022，7，3： | 0 |
