Clinical Application of Perfusion Imaging with Multi-Slice CT in Edema Surrounding Cerebral Neoplasm

LI Zhi-yong,WU Jian-lin,NING Dian-xiu,et al.Department of Radiology,The First Affiliated Hospital,Dalian Medical University,Liaoning 116011,P.R.China  
Objective:The purpose of this study is to discuss perfusion imaging technique with Multi-slice CT and its clinical application value of perfusion parameter of edema areas surrounding cerebral neoplasm.Methods:Eighteen patients with clinically proved brain neoplasm underwent perfusion imaging with 16-slice CT.Among them three cases suffered with cerebral glioma,nine with brain metastasis,six with meningoma.Scanning data were analyzed with perfusion-2 software. Results: CBF value of edema area surrounding cerebral neoplasm:cerebral gliomameningomabrain metastasis.CBV value:cerebral gliomameningomacerebral metastasis;PS value of all tumors increased apparently,PS value of edema area surrounding cerebral neoplasm exceeded obviously that inside neoplasm.Conclusion:PS value in multi-slice CT perfusion imaging is helpful for differential diagnosis of cerebral neoplasm and to display the tumor's true extent.It has a good prospect in clinical application.
