【摘要】 对１９例颅内静脉窦血栓形成患者进行比较放射学分析。１９例ＣＴ检查全部误诊，有的误诊长达１０年。ＭＲＩ对本病的敏感性和准确性均佳，此１９例ＣＴ误诊者均首次经ＭＲＩ检查即明确诊断，并为ＭＲＡ和ＤＳＡ（１５例）所证实。本病早期明确诊断早期治疗预后较佳，但若误诊使病程拖延则很难治愈。因此选择合理的影像学检查对早期诊断殊为重要。更多还原

【Abstract】 Nineteen cases with intracranial sinovenous thrombosis were analysed by comparative radiology. All cases were misdiag- nosed by CT, some even as long as ten years. MRI was a sensitive and accurate diagnostic method for sinovenous thrombosis. All nineteen cases with sinovenous thrombosis misdiagnosed by CT had a correct diagnosis with first MRI examination, and fifteen cases were further verified by MRA and DSA. Exact diagnosis and appropriate treatment during the early stage will make a better prognosis, while misdiagnosis will delay the course of disease and make a bad prognosis. It is important to se- lect a reasonable imaging examination for early diagnosis.更多还原
