Abstract:
Objective To explore the feasibility of in vitro biological soft tissue imaging by using synchrotron radiation phase contrast CT.Methods Three samples of resected human cardia,two samples of resected human esophageal carcinoma and esophagus,as well as two samples of middle cerebral artery tissue extracted from corpses were fixed and airdried at room temperature for synchrotron radiation phase contrast CT imaging.The images of soft tissue structures were observed and compared with pathological findings.Results The images of synchrotron radiation phase contrast CT showed three-layer structure of cardia and esophagus,mucous,submucosa and muscular layer.The surface of mucous layer was smooth.The images of esophageal carcinoma showed cancerous tissue infiltrating esophageal wall.The wall and lumen of cerebral arteries could be also clearly displayed.Conclusion Synchrotron radiation phase contrast CT imaging can clearly display fine structures of in vitro biological soft tissue.
