摘　　要：目的探讨320排动态容积CT全脑灌注成像在颅脑病变诊断中的应用价值。方法对颅脑病变患者分别采用320排动态容积CT(88例)和64排螺旋CT扫描(46例),比较两组间的剂量长度乘积和有效剂量值,并进行对比。结果 320排CT扫描的平均有效剂量值为(3.28±0.36)m Sv,64排CT扫描的平均有效剂量值为(10.15±0.59)m Sv。结论 320排动态容积CT全脑灌注成像具有图像质量高、有效剂量低等特点,具有一定的推广价值。Objective To explore the application value of whole brain perfusion imaging with 320-row dynamic volume CT in the diagnosis of craniocerebral diseases.Methods 88 patients who suffered from craniocerebral diseases were performed with 320-row dynamic volume CT scan and and 46 patients who suffered from craniocerebral diseases were performed with 64 row helical CT scan respectively. And then the dose length product （DLP） and effective dose （ED） of the two groups were compared.Results The average ED of 88 patients performed with 320-row dynamic volume CT scan was（3.28±0.36） mSv, and that of 46 patients performed with 64 row helical CT scan was（10.15±0.59）mSv.ConclusionThe whole brain perfusion imaging with 320-row dynamic volume CT has the advantages of high image quality and low effective dose and is worthy to be promoted.
