摘要
目的分析探讨磁共振成像(MRI)及磁共振静脉系成像(MRVI)对颅内静脉窦血栓的诊断价值。方法选取本院2015年3月至2019年6月收治的30例经临床确诊为颅内静脉窦血栓患者,首先开展MRI平扫,然后开展MRVI扫描、MRI增强扫描,分析颅内静脉窦血栓的检出情况。结果患者经数字减影血管造影检查,共诊断出静脉窦血栓36个。MRI扫描后共检出30个静脉窦血栓,临床检出率为83.33%(30/36);MRVI扫描后共检出32个静脉窦血栓,临床检出率为88.89%(32/36);增强扫描后共检出34个静脉窦血栓,临床检出率为94.44%(34/36)。MRI平扫和增强扫描结果发现,受累部位静脉窦内无流空效应,存在血栓混杂信号,其中8例T1WI、T2WI均表现为高信号,5例T1WI表现为稍低信号,T2WI表现为低信号。结论采用磁共振成像及磁共振静脉系成像能准确诊断颅内静脉窦血栓,具有临床推广价值。
Objective To analyze the diagnostic value of magnetic resonance imaging(MRI)and magnetic resonance venous system imaging(MRVI)in intracranial venous sinus thrombosis.Methods 30 patients admitted to our hospital from March 2015 to June 2019 who were clinically diagnosed with intracranial venous sinus thrombosis were selected.MRI plain scan was first performed,followed by MRVI scan and MRI enhanced scan,and the detection of intracranial venous sinus thrombosis were analyzed.Results 36 cases of venous sinus thrombosis were diagnosed by digital subtraction angiography.A total of 30 venous sinus thrombosis were detected after MRI scan,and the clinical detection rate was 83.33%(30/36).A total of 32 venous sinus thrombosis were detected after MRVI scan,and the clinical detection rate was 88.89%(32/36).A total of 34 venous sinus thrombosis were detected after enhanced scan,with a clinical detection rate of 94.44%(34/36).MRI plain scan and enhanced scan showed that there was no emptying effect in the venous sinus of the affected site,and there were mixed signals of thrombosis.In 8 cases,both T1WI and T2WI showed high signal.5 cases of T1WI showed slightly low signal,and T2WI showed low signal.Conclusion Magnetic resonance imaging and venous system imaging can accurately diagnose intracranial venous sinus thrombosis.
