3D image analysis

  • 文章类型: Systematic Review
    目的:确定用于牙菌斑检测的新型数字化工具的有效性和可靠性,并探讨其使用相关的益处和局限性。
    方法:报告遵循系统评论和Meta分析(PRISMA)扩展范围评论的首选报告项目。包括将使用数字化系统的牙菌斑检测与标准参考进行比较的所有人类临床研究。
    方法:PubMed和Scopus于2013年1月1日至2023年9月28日进行筛查。手动搜索了主要研究的参考书目和主要的同行评审的科学期刊。
    方法:最初的搜索确定了576篇文章,审查共包括13项,2015年至2023年出版。大多数研究(77%)是横断面的,其中三项是前瞻性的。数字设备通过摄像头和口腔扫描仪捕获2D和3D图像,分别。Turesky改良菌斑指数是最常见的临床指标。与临床检查的相关性为中强,具有良好到良好的系统内和系统间协议。
    结论:在本范围审查的局限性内,基于图像分析的斑块检测系统与临床斑块指标具有良好的相关性,使用2D和3D成像系统。虽然数字斑块检测设备在程序标准化和可重复性方面具有优势,它们也有局限性,因此,目前,其应用应以全面的临床检查为基础。
    结论:数字斑块检测工具,提供标准化的测量和存储采集的图像,促进更知情的反馈给患者。这种客观分析可以增强临床医生对其用于临床试验和其他应用的信心。
    To determine the validity and reliability of novel digitalized tools for dental plaque detection and explore the benefits and limitations connected to their use.
    Reporting followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Extension for Scoping Reviews. All human clinical studies comparing dental plaque detection using digitalized systems against a standard reference were included.
    PubMed and Scopus were screened from 01 January 2013 to 28 September 2023. Bibliographies of primary studies and principal peer-reviewed scientific journals were manually searched.
    The initial search identified 576 articles, with a total of 13 included in the review, published between 2015 and 2023. Most of the studies included (77 %) were cross-sectional with three being prospective. Digital devices captured 2D and 3D images via cameras and intra-oral scanners, respectively. The Turesky\'s modified plaque index was the most frequent clinical index. Correlation with clinical examination was moderate to strong, with good to excellent intra- and inter-system agreement.
    Within the limitations of this scoping review, image analysis-based plaque detection systems demonstrated good correlations with clinical plaque indices, using both 2D and 3D imaging systems. Whilst digital plaque detection devices offer advantages in terms of procedural standardization and reproducibility, they also have limitations, therefore currently, their application should be underpinned by a comprehensive clinical examination.
    Digital plaque detection tools, that provide standardized measurements and store acquired images, facilitate more informed feedback to patients. This objective analysis may enhance clinician confidence in their utility for clinical trials and other applications.

    胰腺被认为是由两个独立的器官系统组成,内分泌和外分泌胰腺。虽然治疗具有内分泌或外分泌发病机制的疾病可能会影响整个胰腺的功能,胰腺疾病已经由不同医学学科的临床医生治疗,包括内分泌学家和胃肠病学家。长期以来,人们一直认为胰岛微循环的调节与外分泌胰腺的调节无关。一种新的模型提出胰岛血流与周围的外分泌毛细血管网络整合。这个最近的模型可能会提供复活的或对比的假设来检验,因为胰腺微循环对胰岛激素以及腺泡胰腺功能的调节具有重要意义。在这个小型审查中,描述了胰岛微循环的体内和原位研究的实际应用,特别强调大规模数据分析,以确保考虑已知胰岛异质性的足够样本量。对于体内小动物研究,基于双光子激发显微镜的活体显微镜是一种强大的工具,可以捕获单个荧光标记红细胞的流向和速度。互补,用于血管的结构分析,最近技术进步的共聚焦显微镜和组织清除使我们能够成像厚组织切片中的三维网络结构。
    The pancreas is regarded as consisting of two separate organ systems, the endocrine and exocrine pancreas. While treatment of a disease with either an endocrine or exocrine pathogenesis may affect the function of the entire pancreas, the pancreatic diseases have been treated by clinicians in different medical disciplines, including endocrinologists and gastroenterologists. Islet microcirculation has long been considered to be regulated independently from that of the exocrine pancreas. A new model proposes that pancreatic islet blood flow is integrated with the surrounding exocrine capillary network. This recent model may provide revived or contrasting hypotheses to test, since the pancreatic microcirculation has critical implications for the regulation of islet hormones as well as acinar pancreas functions. In this mini-review, practical applications of in vivo and in situ studies of islet microcirculation are described with a specific emphasis on large-scale data analysis to ensure sufficient sample size accounting for known islet heterogeneity. For in vivo small animal studies, intravital microscopy based on two-photon excitation microscopes is a powerful tool that enables capturing the flow direction and speed of individual fluorescent-labeled red blood cells. Complementarily, for structural analysis of blood vessels, the recent technical advancements of confocal microscopy and tissue clearing have enabled us to image the three-dimensional network structure in thick tissue slices.
