宝石CT碘-水基图在急性脑梗死介入治疗后的应用

摘要
目的探讨宝石CT碘-水基图在急性脑梗死介入治疗后的诊断价值。方法 31例急性脑梗死患者介入治疗后即刻宝石CT平扫QC图发现颅内异常高密度影,采用碘-水基图进行重建分析,同时测定高密度影碘基值、水基值,并与术后24 h普通CT复查诊断结果作比较。结果通过采用碘-水基图,17例诊断为碘对比剂渗出,14例诊断为脑出血转化,与术后24 h普通CT复查诊断结果完全一致(Kappa=1,P<0.01);术后即刻碘基图之碘基值:碘对比剂渗出(32.09±5.36) g/L,脑出血转化(6.86±2.26) g/L,二者差异有统计学意义(t=53.291,P<0.01);术后即刻水基图之水基值:碘对比剂渗出(1 027.93±8.29) g/L,脑出血转化(1 069.68±7.18) g/L,二者差异有统计学意义(t=-8.897,P<0.01)。结论宝石CT碘-水基图可以准确诊断急性脑梗死介入治疗后颅内碘对比剂渗出和脑出血转化,值得向临床介绍推广。
Aim To evaluate the diagnostic value of gemstone CT iodine-water based images for acute cerebral infarction after interventional therapy.Methods 31 patients with acute cerebral infarction were found to have abnormal intracranial high density on the immediate gemstone CT scan QC images after the interventional therapy.Iodine-water based images were used to reconstruct and analyze the images.Simultaneously,the iodine based value and water based value of high density were measured,and the images were compared with the results of 24 h ordinary CT review.Results By using iodine-water based images,17 cases were diagnosed as iodine contrast agent exudation,14 cases were diagnosed as cerebral hemorrhage transformation,which were identical with the results of 24 h ordinary CT reexamination(Kappa=1,P<0.01).The immediate postoperative iodine based value:iodine contrast agent exudation(32.09±5.36) g/L,cerebral hemorrhage transformation(6.86±2.26) g/L,there was statistical significant difference(t=53.291,P<0.01).The immediate postoperative water based value:the iodine contrast agent exudation(1 027.93± 8.29) g/L,the cerebral hemorrhage transformation(1 069.68±7.18) g/L,there was statistical significant difference(t=-8.897,P<0.01).Conclusion Gemstone CT iodine-water based images can accurately diagnose intracranial iodine contrast agent exudation and cerebral hemorrhage transformation after interventional therapy for acute cerebral infarction,which is worthy of clinical promotion.
