Multimodal Imaging Based on Pathological and Genomic Characteristics

A New Multimodal Imaging Technique Based on Pathological and Genomic Characteristics of Gastrointestinal Mucosa

Mitochondrial DNA mutations in normal gastric tissue, early gastric cancer and advanced gastric cancer were identified by single cell sequencing, and the origin of gastric stem cells was traced and new molecular markers were found. At the same time, organize industry-university-research-medical inspection joint research, aiming at the advanced layout of new structural and functional imaging technologies, combined with some new imaging technologies, such as holography, fluorescence, etc., to explore and develop a new composite endoscopic imaging technology that is advanced, original and suitable for China's national conditions, in order to develop a prototype of multimodal structural and functional imaging digestive endoscope without contrast agent.

Studieoversigt

Detaljeret beskrivelse

In this study, on the basis of previous work, aiming at the visualization of key molecular functions of gastric cancer, a full-chain digestive endoscopic diagnosis system was constructed by using cross-scale medical imaging technology. Mitochondrial DNA mutations in normal gastric tissue, early gastric cancer and advanced gastric cancer were identified by single cell sequencing, and the origin of gastric stem cells was traced and new molecular markers were found. The tissue characteristics are analyzed by the full spectrum imaging device, and the location, distribution and aggregation of key molecules on the cell membrane are observed by the high resolution imaging device, so as to develop an imaging probe with high labeling efficiency and biosafety, and to explore its clinical application to realize the information fusion of structural and functional imaging in the evolution and diagnosis and treatment of gastrointestinal tumors. The structural heterogeneity and molecular heterogeneity of gastrointestinal tumors are clarified from the macro-micro levels, and the full-scale imaging system with the most comprehensive visualization and resolution ability is established from multi-information dimensions and multi-imaging scales.
