目的评价同步辐射单色线X线摄影系统在显示小血管和外周分泌管中的作用。材料与方法在14只麻醉犬中进行各种器官的X线摄影试验，并在切除的人胰腺中进行胰腺摄影，采用以下系统：能量水平刚好高于碘的k吸收边的单色同步辐射作为X射线源，高清晰度电视系统，高光敏度图像拾取管摄像机与荧光屏耦合作为检测器。结果该系统可以显示心脏（穿壁动脉）、大脑（直接在Willis环中出现的穿通动脉）和肠道器官（直血管及其粘膜下交通）的小血管（直径< 50-100微米）以及胰管的小分支（下至第五级）。结论同步辐射系统可用于评价人体各器官微循环障碍和早期恶性肿瘤。
PURPOSE To evaluate the usefulness of a radiographic system with monochromatic synchrotron radiation to depict small vessels and peripheral secretory ducts. MATERIALS AND METHODS Radiography of various organs was tested in 14 anesthetized dogs and pancreatography was performed in an excised human pancreas by using the following system: monochromatic synchrotron radiation with an energy level just above the k absorption edge of iodine as an x-ray source and a high-definition TV system with a high-light-sensitivity image pick-up tube camera coupled with a fluorescent screen as a detector. RESULTS This system allowed depiction of small vessels (diameter < 50-100 microns) of the heart (penetrating transmural artery), brain (perforating arteries that arise directly in the circle of Willis), and intestinal organs (vasa recta and their submucosal communications) and of small branches (down to the fifth order) of the pancreatic duct. CONCLUSION The synchrotron radiation system may be useful for evaluating microcirculatory disorders and early-stage malignant tumors in various human organs.
