目的:

探讨LAVA-FLEX成像技术在胰腺肿瘤诊断中的应用价值。

方法:

收集12例经病理证实的胰腺癌患者,术前行3.0T磁共振常规序列、DWI和LAVA-FLEX序列检查,观察与分析LAVA-FLEX序列与常规扫描序列在胰腺癌病变的敏感性和特异性。

结果:

12例胰腺癌在常规序列显示胰腺癌为长T2信号灶8例,略长T2信号2例,等T2信号2例,12例在DWI均呈高信号,T1WI呈等信号。LAVA-FLEX序列图像质量高,压脂均匀,组织对比度高,扫描速度快,12例胰腺癌均呈低信号,较常规T1WI具有明显优势。注射对比剂增强后特征性明显。

结论:

LAVA-FLEX序列作为新技术,在胰腺癌诊断中具有与DWI相近的特异性与敏感性,可取代常规T1WI、压脂T1WI和3D动态增强T1WI序列。

Objective:

To investigate the diagnostic value of 3.0T magnetic resonance LAVA-FLEX sequence in detecting pancreatic adenocarcinoma.

Methods:

12 patients with pathologically proved pancreatic adenocarcinoma were enrolled in this study, whose imaging data of LAVA-FLEX and conventional sequences and DWI preoperative with 3.0T MRI prior to surgery were analyzed in terms of the sensitivity and specificity.

Results:

8 cases showed long T2 signal, 2 showed slightly long T2 signal, and 2 showed even T2 signal. All 12 cases showed high signal in DWI, and the same signal intensity in T1WI. LAVA-FLEX showed low signal in all 12 cases, indicating an obvious advantage over the conventional T1WI.

Conclusions:

LAVA-FLEX as a new technology sequence, has similar specificity and sensitivity as DWI in diagnosis of pancreatic adenocarcinoma, and it can replace the conventional T1WI, Fat-saturation T1WI and 3D dynamic enhanced T1WI.
