    【摘要】 急性脑梗死具有病发时间短、治疗效率较低、死亡率较高、后遗症强等典型特征，严重威胁中老年人生命健康。良好的侧支循环可以缩小梗死体积，降低脑梗死的复发风险、改善患者的预后。有效建立侧支循环不仅可以减少神经损伤的发生，还可以降低二次脑梗死发生风险。双能CT可以利用钙化分布图来区分颅内出血灶和钙化灶，可以辅助急性脑梗死血管内治疗后早期颅内出血的诊断。探讨双能CT评估急性脑梗死侧支循环对患者的临床决策以及预后具有重要意义，因此本文对双能CT在评估急性脑梗死侧支循环的研究进展进行综述。

    Research Progress of Dual-energy CT in Evaluating Collateral Circulation of Acute Cerebral Infarction/YAN Jingwei. //Medical Innovation of China， 2024， 21(04)： -179

    [Abstract] Acute cerebral infarction has the typical characteristics of short onset time， low treatment efficiency， high mortality and strong sequelae， which seriously threatens the life and health of middle-aged and elderly people. Good collateral circulation can reduce the volume of infarction， reduce the risk of recurrence of cerebral infarction and improve the prognosis of patients. Effective establishment of collateral circulation can not only reduce the occurrence of nerve injury， but also reduce the risk of secondary cerebral infarction. Dual-energy CT can distinguish intracranial hemorrhage and calcification by calcification map ......
