| 目的 探讨320排4D-CTA诊断及评估颅内硬脑膜动静脉瘘（DAVF）的价值。方法 回顾性分析23例经DSA确诊的DAVF患者的4D-CTA资料。由2名医师采用盲法分析4D-CTA图像，评估DAVF部位、供血动脉及静脉引流类型，分析医师间以及4D-CTA与DSA间评估上述指标的一致性。结果 23例患者共27个DAVF，对于判断DAVF部位和引流类型，医师间一致率均为96.30%（26/27），一致性均好（Kappa=0.94），4D-CTA与DSA间一致率均为100%（27/27），一致性均好（Kappa=1.00）；医师间及4D-CTA与DSA间检出供血动脉数量差异均无统计学意义（χ2=24.50、21.00，P均>0.05）。结论 320排4D-CTA可准确诊断及评估DAVF部位、供血动脉及静脉引流类型，具有重要临床应用价值。 |

| Objective To explore the value of 320-slice 4D-CTA in diagnosis and assessment of intracranial dural arteriovenous fistulas (DAVF). Methods 4D-CTA data of 23 patients with DAVFs confirmed by DSA were retrospectively reviewed. The location, the main arterial feeders and the venous drainage type of the DAVFs were independently assessed by two neuroradiologists blindly. The inter-observer and inter-modality consistency in assessment of above indicators was analyzed, respectively. Results There were 27 DAVFs in the 23 patients. For assessment of the location and the venous drainage type of the DAVFs, the consistencies of inter-observer were good (both Kappa=0.94) with consistent rate of 96.30% (26/27), and the consistencies between 4D-CTA and DSA were also good (both Kappa=1.00) with consistent rate of 100% (27/27). There were no significantly differences of the main arterial feeder number between different observers as well as 4D-CTA and DSA (χ2=24.50, 21.00, both P>0.05). Conclusion 320-slice 4D-CTA is accurate in evaluation of the location, and the main arterial feeders and the venous drainage of DAVFs have important clinical application value. |
