Abstract:
Objective To intruduce a method of making cerebral perfusion mapping and measurement using dynamic CT with a personal computer. Methods We generated the cerebral perfusion mapping and measurement from a series dynamic CT images with a personal computer. The theoretic basis of our technique is central volume principle. The application software was made using visual C++ language with Windows 98 platform. Results This method was applied to a case of transient ischemic attack (TIA). The cerebral perfusion mapping contributed to display the abnormal area of ischemia, which showed as normal imaging appearances in routine CT and MR images. Conclusion Personal computer aided mapping and measurement of cerebral perfusion with dynamic CT is a simple and accessible technique for delineating the hemodynamic response, including abnormal regional cerebral blood flow, blood volume, mean transit time, and time to peak in cases of hyperacute ischemic stroke which was viewed as normal imaging findings in routine CT and MR examination. This method is more suitable to examine emergency cases than MR perfusion imaging and may be used in any facility where CT scanner and personal computer are available.
