摘要目的 FLAIR血管高信号征(FVH)最初描绘于2D液体反转恢复序列(FLAIR)上,是急性缺血性脑卒中病人的一个有用的影像学指标。该项研究的目的是比较3D CUBE FLAIR及2D FLAIR在显示血管高信号征的敏感性是否存在差异。方法 47例可疑脑卒... 详细信息

摘要目的 FLAIR血管高信号征(FVH)最初描绘于2D液体反转恢复序列(FLAIR)上,是急性缺血性脑卒中病人的一个有用的影像学指标。该项研究的目的是比较3D CUBE FLAIR及2D FLAIR在显示血管高信号征的敏感性是否存在差异。方法 47例可疑脑卒中病人在1.5 T及3.0 T MR设备上均行2D FLAIR及3D CUBE FLAIR序列扫描。通过盲法让3名评估员对"FLAIR血管高信号征"进行评价,"FLAIR血管高信号征"定义为大脑动脉内的高信号。对局限性的"FLAIR血管高信号征"、急性脑梗死及动脉狭窄也进行了评估,2D

摘要目的评价CT用于诊断结直肠术后吻合口瘘的准确性。方法 2名放射科医师对连续的153例(结直肠术后60 d内)疑似吻合口瘘的病人的CT检查进行双盲阅片,与进行(n=58)或未进行(n=95)逆行造影灌肠(RCE)的检查结果进行比较。参考标准为再次... 详细信息

摘要目的评价CT用于诊断结直肠术后吻合口瘘的准确性。方法 2名放射科医师对连续的153例(结直肠术后60 d内)疑似吻合口瘘的病人的CT检查进行双盲阅片,与进行(n=58)或未进行(n=95)逆行造影灌肠(RCE)的检查结果进行比较。参考标准为再次手术或放射科医生、外科医生依据临床、实验室、影像检查及治疗后随访资料达成的共识。结果 34/131病人存在吻合口瘘。对于2名阅片者和RCE检查结果,CT的敏感度分别为82%、87%和71%,特异度分别为84%、84%和92%。RCE明显提高阳性预测值(从40%到
