脑血流储备是评价脑血管病的一项重要参数,临床意义重大。脑血流储备的检测方法较多,如正电子发射体层摄影、单光子发射计算机体层摄影、氙吸入技术、氙-CT、灌注CT、MRI、经颅多普勒、经颅超声波谐振灌流成像、近红外线光谱、激光多普勒,但迄今尚无统一的标准。使脑血流增加的激发试验包括CO_2吸入试验、屏气试验、乙酰唑胺试验等。文章重点阐述了各种检测方法的优缺点。
Cerebral blood flow reserve is an important parameter to evaluate cerebrovascular disease, which is of great clinical significance. Cerebral blood flow reserve detection methods are more, such as positron emission tomography, single photon emission computed tomography, xenon inhalation technology, xenon-CT, perfusion CT, MRI, transcranial Doppler, transcranial ultrasound resonance perfusion Imaging, near infrared spectroscopy, laser Doppler, but so far there is no uniform standard. Excitation test to increase cerebral blood flow include CO 2 inhalation test, breath hold test and acetazolamide test. The article focuses on the advantages and disadvantages of various detection methods.
