Application of stressed cerebral blood flow perfusion imaging in cerebrovascular disease

The incidence of ischemic cerebrovascular disease is currently high. The disease can be diagnosed and treated by numerous methods, including transcranial doppler, CT angiography, MRI, digital subtraction angiography and cerebral blood flow perfusion imaging of resting and stress states. In these methods, the clinical application of stressed cerebral blood flow perfusion imaging is very wide and includes vertical load tests, CO₂ inhalation load tests, acetazolamide stress tests, dipyridamole stress tests, and adenosine stress tests. Stressed cerebral blood flow perfusion imaging can provide an objective basis for the early diagnosis, curative effect evaluation, prognostic estimation, and evaluation of brain reserve function.
