Trustworthy AI is critical for effectively adopting AI systems in medical imaging and broader healthcare contexts. While the Trustworthy AI framework defines seven core principles —ranging from technical robustness to societal well-being— these are often addressed in isolation, lacking a coherent integration strategy. In this perspective paper, we propose a unified, layered framework that organizes these principles across three tiers of increasing trust: core operations, feedback, and explainability. Each layer aligns with the fundamental components of an AI system—input data, model, and outputs, integrating the different principles and offering a structured path toward increasing levels of trust. Central to our framework is technical robustness, positioned as a cross-cutting enabler that intertwines with the other trust principles across all layers. Through this lens, we review recent advances in trustworthy AI techniques in medical imaging and highlight persistent challenges and future research directions for building trustworthy AI systems in medical imaging.
值得信赖的人工智能对于在医学成像和更广泛的医疗保健环境中有效采用人工智能系统至关重要。虽然值得信赖的人工智能框架定义了七个核心原则——从技术稳健性到社会福祉——但这些原则往往是孤立地解决的,缺乏连贯的整合战略。在这篇透视文章中,我们提出了一个统一的、分层的框架,将这些原则组织在三个增加信任的层次上:核心业务、反馈和可解释性。每一层都与人工智能系统的基本组成部分保持一致——输入数据、模型和输出,整合不同的原则,并为提高信任水平提供结构化的路径。我们框架的核心是技术健壮性,定位为跨所有层与其他信任原则交织在一起的横切推动者。通过这一视角,我们回顾了医学成像中可信人工智能技术的最新进展,并强调了构建医学成像中可信人工智能系统的持续挑战和未来的研究方向。

Multimodal artificial intelligence (MMAI) is reshaping the landscape of next-generation healthcare by integrating diverse data sources—ranging from medical imaging and electronic health records (EHRs) to wearable sensor data and genomic sequencing. This convergence enables more accurate diagnostics, personalized treatment strategies, and real-time patient monitoring, ultimately transforming healthcare from reactive to predictive and preventive. Additionally, MMAI can lead to improved operational efficiency by enabling automated reporting and streamlining clinical workflows, helping to reduce clinician burnout and accelerate diagnostic turnaround times. Despite significant advancements, several challenges hinder the widespread adoption of MMAI, including data fragmentation, interoperability issues, computational demands, and the need for explainable AI in clinical decision-making. This opinion paper explores four key aspects driving the future of MMAI in healthcare: (1) the evolution of multimodal data; (2) advancements in AI models and fusion strategies for extracting insights from heterogeneous data streams; (3) major challenges such as synchronization across modalities, interpretability, and regulatory constraints; and (4) emerging future directions, including the role of digital twins, automated clinical reporting, and precision medicine.
多模式人工智能(MMAI)通过整合各种数据源(从医学成像和电子健康记录(EHRs)到可穿戴传感器数据和基因组测序),正在重塑下一代医疗保健的格局。这种融合可以实现更准确的诊断、个性化治疗策略和实时患者监控,最终将医疗保健从被动转变为预测和预防。此外,MMAI可以通过实现自动化报告和简化临床工作流程来提高操作效率,帮助减少临床医生的倦怠并加快诊断周转时间。尽管取得了重大进展,但仍存在一些挑战阻碍了MMAI的广泛采用,包括数据碎片化、互操作性问题、计算需求以及在临床决策中对可解释的人工智能的需求。本文探讨了推动医疗保健领域MMAI未来发展的四个关键方面:(1)多模态数据的演变;(2)从异构数据流中提取见解的人工智能模型和融合策略的进展;(3)主要挑战,如跨模式的同步、可解释性和监管约束;(4)新兴的未来方向,包括数字双胞胎的作用、自动临床报告和精准医疗。

This review article explores the significant advancements of artificial intelligence (AI) as a transformative tool for the early detection of major neurodegenerative diseases, specifically Alzheimer’s disease (AD) and Parkinson’s disease (PD). Traditional diagnostic techniques, including standardized clinical cognitive assessments, molecular biomarker analysis, and neuroimaging, remain crucial in clinical assessment. However, their utility is often limited by their accessibility, cost, and insufficient sensitivity. In the recent years, AI-driven techniques have emerged as a promising tool in advancing the early detection of AD and PD. These techniques play a crucial role in diagnosis by analyzing complex dataset derived from neuroimaging, integrated wearable sensors, and various digital biomarkers. By integrating multimodal data analysis with digital phenotyping and digital biomarkers discovery, a personalized therapeutic regime can be developed. Challenges, including the need for standardized data acquisition, improving model interpretability, and addressing ethical concerns related to data privacy and equitable access, are also highlighted.

Engineering stimuli-responsive extracellular vesicles for enhanced anticancer therapeutics 工程刺激反应细胞外囊泡增强抗癌治疗
IF 4.2 3区 工程技术 Q2 ENGINEERING, BIOMEDICAL Pub Date : 2026-03-01 Epub Date: 2025-11-26 DOI: 10.1016/j.cobme.2025.100634

Extracellular vesicles (EVs), the so-called nanosized vesicles shedding out from cells, have emerged as promising nanocarriers for cancer therapy given their high biocompatibility and low immunogenicity. However, their clinical utility remains limited by challenges such as off-target, premature drug release and rapid clearance. In solid tumors, these issues are further compounded by the hostile biomechanical environment, including stiff extracellular matrix, elevated interstitial fluid pressure, and abnormal vasculatures, which further complicates drug delivery and therapeutic efficacy. To overcome these limitations, recent efforts have focused on engineering stimuli-responsive EVs that respond to internal stimuli (e.g. pH, enzymatic activity, and redox imbalance) or external stimuli (e.g. magnetic fields, light, ultrasound, and temperature), as well as combinations thereof. These smart nanoplatforms have demonstrated a superior capacity in achieving controlled drug release, enhancing tumor targeting, and improving deep tissue penetration. In this minireview, we highlight how stimuli-responsive EVs surpass tumor biomechanics for cancer therapy and discuss key considerations for future development and clinical translation.
细胞外囊泡(EVs),即所谓的从细胞中脱落的纳米级囊泡,由于其高生物相容性和低免疫原性,已成为癌症治疗的有前途的纳米载体。然而,它们的临床应用仍然受到脱靶、药物过早释放和快速清除等挑战的限制。在实体瘤中,这些问题进一步加剧了恶劣的生物力学环境,包括僵硬的细胞外基质、升高的间质液压力和异常的血管,这进一步复杂化了药物递送和治疗效果。为了克服这些限制,最近的努力集中在工程刺激响应型电动汽车上,这些电动汽车可以响应内部刺激(例如pH值、酶活性和氧化还原失衡)或外部刺激(例如磁场、光、超声波和温度),以及它们的组合。这些智能纳米平台在控制药物释放、增强肿瘤靶向和改善深层组织渗透方面表现出卓越的能力。在这篇小型综述中,我们强调了刺激反应性ev如何超越肿瘤生物力学来治疗癌症,并讨论了未来发展和临床转化的关键因素。

Obesity triggers ample reorganization of adipose tissue through mechanical and biological mechanisms that extend beyond simple energy storage. Here, we analyse how the extracellular matrix (ECM) mechanically controls obesity's effects on tissue function. We examine three interconnected mechanisms: first, how obesity triggers cellular adaptations through hypertrophy, hyperplasia, and phenotypic transitions; second, how these changes activate specific mechanosensitive pathways through ECM-generated forces; and third, how the resulting matrix alterations promote breast cancer progression through coordinated changes in adipocyte phenotype and tissue mechanics. We critically evaluate current in vitro models for studying these processes and discuss their limitations in recapitulating the complex adipose-tumour microenvironment. By elucidating these ECM-mediated mechanisms, we identify potential therapeutic targets for obesity-related pathologies, particularly breast cancer, while noting the broader applicability of these mechanobiological principles to other adipose-associated malignancies.
肥胖通过超出简单能量储存的机械和生物机制触发脂肪组织的大量重组。在这里,我们分析细胞外基质(ECM)如何机械地控制肥胖对组织功能的影响。我们研究了三个相互关联的机制:首先,肥胖如何通过肥大、增生和表型转变触发细胞适应;其次,这些变化如何通过ecm产生的力激活特定的机械敏感途径;第三,由此产生的基质改变如何通过脂肪细胞表型和组织力学的协调变化促进乳腺癌的进展。我们批判性地评估了目前用于研究这些过程的体外模型,并讨论了它们在概括复杂脂肪-肿瘤微环境方面的局限性。通过阐明这些ecm介导的机制,我们确定了肥胖相关病理,特别是乳腺癌的潜在治疗靶点,同时注意到这些机制生物学原理在其他脂肪相关恶性肿瘤中的广泛适用性。

Transdermal nanomedicine integrates nanotechnology with drug-delivery science to overcome the formidable skin barrier, offering a noninvasive, patient-centric alternative to oral and injectable routes. This review traces its evolution from conventional patches to nano-enabled systems, critically appraising lipid and polymeric nanoparticles, nanogels, solid and nanostructured lipid carriers, and microneedle-assisted delivery. Key permeation strategies surface engineering, follicular targeting, and stimuli-responsive designs are discussed alongside bioinspired carriers such as cell-membrane-coated, exosome-derived, and virus-like particles that enhance precision and biocompatibility. Structural biomimetics, including adhesive and proboscis-inspired microneedles, further advance patch design. Persistent challenges reproducibility, chronic toxicity, scale-up, and regulatory heterogeneity are analyzed with emphasis on standardization and long-term safety. Emerging solutions combine microfluidic and 3D-printed fabrication, self-assembling nanostructures, and advanced characterization (SANS/SAXS) under Quality-by-Design and AI-guided frameworks. By integrating materials science, skin biology, and regulatory insight, this review delineates a roadmap toward clinically translatable, personalized transdermal therapeutics.

Mechanobiological modulation of extracellular vesicle function and transport dynamics in cancer progression 肿瘤进展中细胞外囊泡功能和运输动力学的机械生物学调节
IF 4.2 3区 工程技术 Q2 ENGINEERING, BIOMEDICAL Pub Date : 2026-03-01 Epub Date: 2025-11-26 DOI: 10.1016/j.cobme.2025.100636

Extracellular vesicles (EVs) are membrane-bound particles secreted by cells into the extracellular space. EVs are recognized as nanotransporters of intercellular communication, particularly within the tumor microenvironment. In cancer, EVs are involved in disease progression by regulating signaling cascades, remodeling the extracellular matrix (ECM), and fostering invasive cell behavior. Recent evidence highlights the central role of mechanical signals of the ECM in regulating EV biogenesis, molecular cargo, and downstream functional effects. Elucidating these mechanobiological processes is crucial for the development of EV-based diagnostics and mechanotherapies. This review integrates new concepts on the biomechanics of EVs and ECM to shed light on their mutual regulation and collective influence on cancer progression. By linking the transport dynamics of EVs to the mechanics of the ECM and transmembrane modulators such as AQP1, it illustrates how biomechanical signals and osmotic gradients control the deformation, migration, and escape of EVs through the complex tumor matrix landscape.
细胞外囊泡(EVs)是由细胞分泌到细胞外空间的膜结合颗粒。ev被认为是细胞间通讯的纳米转运体,特别是在肿瘤微环境中。在癌症中,ev通过调节信号级联、重塑细胞外基质(ECM)和促进侵袭性细胞行为参与疾病进展。最近的证据强调了ECM的机械信号在调节EV生物发生、分子货物和下游功能效应中的核心作用。阐明这些机械生物学过程对于基于ev的诊断和机械治疗的发展至关重要。本文综述了ev和ECM生物力学的新概念,以阐明它们对癌症进展的相互调节和共同影响。通过将ev的运输动力学与ECM和跨膜调节剂(如AQP1)的力学联系起来,该研究说明了生物力学信号和渗透梯度如何控制ev在复杂的肿瘤基质景观中的变形、迁移和逃逸。

EVs are recognized as nanotransporters of intercellular communication, particularly within the tumor microenvironment. In cancer, EVs are involved in disease progression by regulating signaling cascades, remodeling the extracellular matrix (ECM), and fostering invasive cell behavior. Recent evidence highlights the central role of mechanical signals of the ECM in regulating EV biogenesis, molecular cargo, and downstream functional effects. Elucidating these mechanobiological processes is crucial for the development of EV-based diagnostics and mechanotherapies. This review integrates new concepts on the biomechanics of EVs and ECM to shed light on their mutual regulation and collective influence on cancer progression. By linking the transport dynamics of EVs to the mechanics of the ECM and transmembrane modulators such as AQP1, it illustrates how biomechanical signals and osmotic gradients control the deformation, migration, and escape of EVs through the complex tumor matrix landscape.</div></div>","PeriodicalId":36748,"journal":{"name":"Current Opinion in Biomedical Engineering","volume":"37 ","pages":"Article 100636"},"PeriodicalIF":4.2,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145797830","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
