BACKGROUND
We investigated the diagnostic values and artifact severities of 3D-T1W sequences in the diagnosis of cerebrospinal fluid (CSF) leakage.
METHODS
We retrospectively reviewed 3-tesla contrast-material enhanced MR cisternography exams of 22 patients with suspected CSF leakage in 4 years. The presence of the artifacts on 3D-T1W data was evaluated using a 4-point scale (0: none; 1: minimal; 2: moderate; 3: prominent). Agreements between CSF leakage results of the 3D-T1W sequences and consensus decisions were evaluated via kappa values. Artifact scores were analyzed by Fisher's exact test.
RESULTS
The most compatible techniques with the consensus diagnoses were fat-saturated 3D-T1W-SPACE and 3D-T1W-VIBE sequences. The most artifact containing the 3D-T1W sequence was 3D-MPRAGE.
DISCUSSION
3D-SPACE and 3D-VIBE are more successful in evaluating CSF leakages compared to 3D-MPRAGE. 3D-SPACE has lower artifact scores compared to 3D-VIBE and 3D-MPRAGE sequences.
背景
我们研究了三维 T1W 序列在诊断脑脊液（CSF）漏中的诊断价值和伪影严重程度。
方法
我们回顾性分析了 4 年内 22 例疑似 CSF 漏患者的 3 特斯拉增强磁共振脑池造影检查。使用 4 分制（0：无；1：轻微；2：中度；3：明显）评估 3D-T1W 数据上的伪影存在情况。通过 Kappa 值评估 3D-T1W 序列的 CSF 漏结果与共识决策之间的一致性。通过 Fisher 精确检验分析伪影评分。
结果
与共识诊断最匹配的技术是脂肪饱和 3D-T1W-SPACE 和 3D-T1W-VIBE 序列。包含伪影最多的 3D-T1W 序列是 3D-MPRAGE。
讨论
与 3D-MPRAGE 相比，3D-SPACE 和 3D-VIBE 在评估 CSF 漏方面更成功。3D-SPACE 的伪影评分低于 3D-VIBE 和 3D-MPRAGE 序列。
