基层医院开展脑灌注有利于患者及时诊治,但实际工作中常因对比剂注射速率过高致检查失败,限制了这一技术的广泛应用。我们针对8层螺旋CT脑灌注的参数进行优化,取得了满意的效果。材料与方法选择脑缺血病变急性期、脑外伤急性期和亚急性期病例进行CT脑灌注成像图。对比剂使用优 Cerebral perfusion at the grassroots level is good for timely diagnosis and treatment of patients. However, the failure of routine tests often results in failure of examination because of high contrast injection rate, which limits the widespread application of this technique. We optimized the parameters of 8-slice spiral CT cerebral perfusion, and achieved satisfactory results. Materials and Methods CT cerebral perfusion imaging was performed in the acute phase of cerebral ischemia, the acute phase of acute traumatic brain injury and the subacute phase of cerebral trauma. Excellent contrast agent
