We evaluated the detection rate and degree of motion artifact of the modified CAIPIRINHA-VIBE (mC-VIBE) without view-sharing and compare them with the CAIPIRINHA-Dixon-TWIST-VIBE (CDT-VIBE) with view-sharing on multi-arterial gadoxetic acid-enhanced liver MRI in the assessment of hepatocellular carcinoma (HCC).
We retrospectively identified 114 pathological-proven hepatic tumors in 114 patients with risk of HCC who underwent multi-arterial gadoxetic acid-enhanced MRI between June 2016 and June 2018. All patients underwent triple arterial phase imaging using the mC-VIBE without view-sharing (54 patients; 49 HCCs and 5 non-HCCs) or the CDT-VIBE with view-sharing (60 patients; 55 HCCs and 5 non-HCCs). We compared the detection rate of two sequences for HCC, with reference to LI-RADS.V.2017. We also compared the mean motion scores and proportions of transient severe motion (TSM) in two sequences.
For the examination using the mC-VIBE, the HCC-detection rate was significantly higher, compared with that using CDT-VIBE (93.9% [46/49] vs 80.0% [44/55], respectively; p = 0.047). For the examination with the mC-VIBE, mean motion scores were significantly lower compared with those of CDT-VIBE for all multi-arterial phases (1.21, 1.19, and 1.15 vs. 1.82, 1.85, and 1.84, respectively; p < 0.001 for all three comparisons). The proportion of TSM in the CDT-VIBE was significantly higher than that in the mC-VIBE (15.0% [9/60] vs 0.0% [0/54], respectively; p = 0.003).
In multi-arterial phase gadoxetic acid-enhanced MRI, the mC-VIBE sequence without view-sharing has slightly higher HCC-detection rate and fewer motion artifacts compared with CDT-VIBE with view-sharing.
• Multi-arterial phase using the mC-VIBE without view-sharing can overcome motion artifacts, resulting in providing optimal arterial phase imaging. • The HCC-detection rate is slightly higher with the mC-VIBE vs. CAIPIRINHA-Dixon-TWIST-VIBE with view-sharing (CDT-VIBE). • View-sharing of CDT-VIBE in the multi-arterial phase is associated with increased frequency of TSM.
我们评估了改良 CAIPIRINHA-VIBE（mC-VIBE）无视图共享与 CAIPIRINHA-Dixon-TWIST-VIBE（CDT-VIBE）有视图共享在多动脉钆塞酸增强肝脏 MRI 评估肝细胞癌（HCC）中的运动伪影检测率和程度。
我们回顾性分析了 2016 年 6 月至 2018 年 6 月期间 114 例有 HCC 风险的患者进行的多动脉钆塞酸增强 MRI 中 114 例经病理证实的肝肿瘤。所有患者均采用 mC-VIBE 无视图共享（54 例；49 个 HCC 和 5 个非 HCC）或 CDT-VIBE 有视图共享（60 例；55 个 HCC 和 5 个非 HCC）进行三动脉期成像。我们比较了两种序列对 HCC 的检出率，参考 LI-RADS.V.2017。我们还比较了两种序列中平均运动评分和短暂性严重运动（TSM）的比例。
对于 mC-VIBE 检查，HCC 的检出率明显高于 CDT-VIBE（93.9%[46/49]比 80.0%[44/55]；p=0.047）。对于 mC-VIBE 检查，所有多动脉期的平均运动评分均明显低于 CDT-VIBE（1.21、1.19 和 1.15 比 1.82、1.85 和 1.84；p<0.001 三个比较）。CDT-VIBE 中 TSM 的比例明显高于 mC-VIBE（15.0%[9/60]比 0.0%[0/54]；p=0.003）。
在多动脉期钆塞酸增强 MRI 中，无视图共享的 mC-VIBE 序列与有视图共享的 CDT-VIBE 相比，HCC 的检出率略高，运动伪影更少。
多动脉期使用无视图共享的 mC-VIBE 可克服运动伪影，从而提供最佳的动脉期成像。
与 CAIPIRINHA-Dixon-TWIST-VIBE 有视图共享（CDT-VIBE）相比，mC-VIBE 的 HCC 检出率略高。
CDT-VIBE 的多动脉期视图共享与 TSM 频率增加有关。
