In tumor tissues with dense cellularity and complex architecture, water diffusion is restricted. This technique allows for the detection of changes in cell size, shape, and interstitial spaces in liver cancer, providing insights into tumor heterogeneity and microenvironment.\n\nCEST (Chemical Exchange Saturation Transfer)： This is a molecular imaging technique based on chemical exchange. It selectively saturates exchangeable protons on specific molecules (such as proteins, peptides, or metabolites) and detects the transfer of this saturation effect to water protons, enabling indirect measurement of specific molecule concentrations in vivo. In liver cancer research, CEST can detect protein content, pH changes, and metabolic abnormalities in tumor tissues, providing functional information to assess tumor biological be",[23],{"name":24,"role":25,"phone":26,"phoneExt":13,"email":27},"zhen li, PHD","CONTACT","+86 130 3717 8109","zhenli@hust.edu.cn",[29],{"facility":5,"status":30,"city":31,"state":32,"zip":33,"country":34,"countryCode":35,"cosmosGeoPoint":36,"geoPoint":41,"contacts":42},"RECRUITING","Wuhan","Hubei","430000","China","CN",{"type":37,"coordinates":38},"Point",[39,40],114.26667,30.58333,{"lat":40,"lon":39},[43],{"name":44,"role":25,"phone":26,"phoneExt":13,"email":27},"Zhen li, PHD",{"type":46,"investigatorFullName":47,"investigatorTitle":48,"investigatorAffiliation":5,"oldNameTitle":13,"oldOrganization":13},"PRINCIPAL_INVESTIGATOR","Zhen Li","Chief Physician, Professor","100657379","multimodalomics-based-construction-of-spatiotemporal-characteristics-of-dynamic-liver-cancer-microenvironment-to-characterize-the-clinical-application-of-immune-mechanisms-in-liver-cancer-100657379",false,"NCT07838415","Multimodalomics-based Construction of Spatiotemporal Characteristics of Dynamic Liver Cancer Microenvironment to Characterize the Clinical Application of Immune Mechanisms in Liver Cancer","Inclusion Criteria:\n\n1. age 18 years or older, (b) pathologically confirmed HCC with available pathology slides, and (c) EOB-MRI including Td-dMRI within 1 month before surgery.\n\nExclusion Criteria:\n\n* (a) lesions smaller than 1 cm, (b) poor imaging quality, and (c) received other treatments before surgery.","ALL","18 Years","80 Years",{"count":59,"type":60},400,"ESTIMATED","24 Months","OBSERVATIONAL","This study aims to explore whether adding an additional MRI sequence to routine liver scans can better characterize the immune microenvironment of liver cancer.
