PURPOSE
To evaluate magnetic resonance venography (MRV) in the detection of cervical/mediastinal venous thrombosis (CMVT).
METHODS
MR venograms were performed in 20 patients suspected for CMVT. 2D-TOF MR venography was used for all studies. MR and conventional venographic/surgical data were collected prospectively and analyzed in a blinded manner comparatively to other corroborative studies: venography (n = 8), color-Doppler studies (n = 15), CT (n = 12), and/or surgery (n = 6).
RESULTS
MRV was 100% sensitive and 100% specific in the diagnosis of venous thrombosis (VT) of the cervical/mediastinal veins, present in fourteen patients, and 93% accurate in grading the extension of CMVT. MR images showed a greater number of collateral vessels than detected by contrast venography in case of complete cervical/mediastinal venous thrombosis.
CONCLUSION
The positive diagnosis and extent of CMVT can be accurately diagnosed by a non-invasive method such as MRV.
目的
评估磁共振静脉血管造影（MRV）在检测颈部/纵隔静脉血栓形成（CMVT）中的作用。
方法
对20例疑似CMVT的患者进行了MR静脉血管造影检查。所有研究均采用二维时间飞跃法MR静脉血管造影。前瞻性收集MR及传统静脉造影/手术数据，并与其他确证性研究（静脉造影，n = 8；彩色多普勒检查，n = 15；CT，n = 12；和/或手术，n = 6）进行盲法比较分析。
结果
MRV对14例存在颈部/纵隔静脉血栓形成（VT）的患者进行静脉血栓诊断时敏感性为100%，特异性为100%，对CMVT扩展程度分级的准确率为93%。在完全性颈部/纵隔静脉血栓形成的情况下，MR图像显示的侧支血管数量比静脉造影检测到的更多。
结论
CMVT的阳性诊断及范围可通过MRV等非侵入性方法准确诊断。
