【摘要】：目的探讨320排动态容积CT诊断硬脊膜动静脉瘘(SDAVF)的价值。方法对12例临床表现符合脊髓血管畸形患者作CTA(320排CT)和对比增强MRA(CE-MRA)检查,并于1周内作DSA检查,评价CTA成像所示病变范围、供血动脉、瘘口及引流静脉等,并与CE-MRA、DSA检查对照。结果 12例患者经CTA检查均明确显示脊髓异常血管及病变范围,容积再现(VR)、多平面重组(MPR)和最大密度投影(MIP)成像清晰显示畸形血管的供血动脉、瘘口、引流静脉,畸形血管与周围骨性结构空间位置关系。CE-MRA检查显示脊髓畸形血管病变范围,但仅显示8例患者供血动脉及瘘口位置。结论 320排动态容积CT可快速、无创、清晰地显示脊髓血管畸形患者供血动脉、引流静脉及瘘口,弥补了DSA、CE-MRA单一成像的不足,对SDAVF有较高的诊断准确率。
[Abstract]:Objective to evaluate the value of 320-slice dynamic volume CT in the diagnosis of dural arteriovenous fistula (SDAVF). Methods 12 patients with spinal vascular malformation were examined by CTA-320 row CTA and contrast-enhanced MRACE-MRA.DSA was performed within one week to evaluate the extent of lesions, feeding artery, fistula and drainage vein as shown by CTA imaging, and compared with CE-MRA-DSA. Results the abnormal blood vessels of spinal cord and the extent of lesion were clearly demonstrated by CTA in 12 patients. The volume reappearance of VRV, MPRs of multiplanar recombination and maximum density projection of MIP) showed clearly the feeding artery, fistula and drainage vein of the malformed vessels. CE-MRA examination showed the extent of vascular lesions in spinal cord malformation, but only showed the location of feeding artery and fistula in 8 cases. Conclusion 320 slice dynamic volume CT is rapid, noninvasive, and can clearly display the feeding artery, drainage vein and fistula in patients with spinal cord vascular malformation, which makes up for the deficiency of single imaging of DSA-CE-MRA, and has a high diagnostic accuracy for SDAVF.
