Purpose: To investigate the methods and clinical value of MSCT perfusion imaging(MSCTPI) in the brain tumors.Materials and Methods: Conventional CT was performed first to confirm the central part of tumor,,then film-scanning technique of MSCTPI was used in the patients with brain tumor.The scanning images were calculated by software Perfusion2 in ADW4.0 workstation to get perfusion images and data,including Cerebral Blood Flow(CBF), Cerebral Blood Volume(CBV), Mean Transit Time(MTT) and permeability surface(PS). Results: In 27 brain tumors there were 7 Astrocytomas,8 Meningiomas,8 Metastatic Tumors,2 Craniopharygiomas,1 Lymphoma and 1 Hemangioblastoma.All perfusion images could clearly display brain tumors and easily know the difference between tumor and edema.The values of CBF,CBV,MTT,PS were different in different tumor and PS images could clearly display essential part of brain tumors and capillary permeability. Conclusion: MSCTPI provides a new method in quantificational research of brain tumor flow perfusion and is valuable in realizing inner flow state of brain tumor and change of capillary permeability.
