Neuroimaging assessment of collateral circulation in acute cerebral infarction / 医学研究生学报

ABSTRACT

Acute cerebral infarction is a common disease of the central nervous system, the key of the current treatment is to restore blood flow and save ischemic penumbra .The studies have shown that good collateral circulation can reduce the infarction area, improve prognosis.Thus, an accurate and complete evaluation of collateral circulation in the early stage of disease has an important sig -nificance.The development of modern imaging techniques provides important means for the assessment of collateral circulation estab -lishment in acute stroke .In this paper, techniques and methods of the imaging examination of collateral circulation establishment in a -cute cerebral infarction and methods are reviewed, aiming to provide the basis for choosing reasonable imaging modality .
