摘要
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。
Cerebrovascular reserve is an important parameter for evaluating cerebrovascular disease, and it has great clinical significance, There are a number of determination methods for cerebrovascular reserve, such as position emission tomography （PET）, single photon emission computed tomography （SPECT）, Xenon-133 inhalation technique, Xenon CT, perfusion CT, magnetic resonance imaging （MRI）, transcranial Doppler （TCD）, transcranial harmonic perfusion imaging （HPI）, near infrared spectroscopy （NIR）, and Laser Doppler vibrometry （LDV）, however, there have been no unified criteria up to now. The prouocation test that makes cerebral blood flow increase includes CO2 inhalation test, breath holding test, and acetazolamide test, etc. The article focuses the discussion on the advantages and disadvantages of the above determination methods.
