MR Cerebral Perfusion Imaging on Personal Computer

Objective:To introduce a method of making MR cerebral perfusion weighted imaging based on Personal Computer (PC) and probe into the clinical diagnostic value of the method.Methods:MR cerebral perfusion weighted imaging was performed in 5 normal adults and 18 patients with cerebral ischemia.Perfusion-weighted images were analyzed with a software running on PC.Cerebral perfusion mapping with parameters including relative regional cerebral blood flow (rrCBF),relative regional cerebral blood volume (rrCBV),time to peak (TTP) and bolus mean transit time (bMTT) were conducted on PC.Results:The process and analysis could be performed successfully on PC.The cerebral perfusion mapping provided valuable hemodynamic information and showed the extent of perfusion disturbances.Conclusion:PC aided mapping of MR cerebral perfusion weighted imaging [JP2]is a simple and accessible technique for delineating the hemodynamic abnormalities.The methods could obtain more diagnostic information,and has great practical value in both clinical and research workes.
