| 目的 观察基于5.0T MRI的磁敏感加权成像(SWI)诊断肝细胞癌(HCC)合并静脉癌栓的价值。方法 回顾性分析63例HCC患者,其中17例合并静脉癌栓; 观察5.0T SWI检出静脉癌栓的效能,比较5.0T与3.0T 图像质量。结果 5.0T SWI显示16例癌栓,未能检出1例位于门静脉左支左外叶上段的癌栓。5.0T增强MRI门静脉期和肝胆期图像显示肝脏边缘评分、整体图像质量评分、信噪比和对比度噪声比均高于3.0T(P均<0.05)。结论 5.0T SWI有助于诊断HCC合并静脉癌栓。 |

| Objective To observe the value of susceptibility weighted imaging (SWI) based on 5.0T MRI for diagnosing hepatocellular carcinoma (HCC) complicated with vein tumor thrombi. Methods Totally 63 HCC patients were retrospectively enrolled, among them 17 complicated with vein tumor thrombi. The efficacy of 5.0T SWI for detecting vein tumor thrombus was observed, and the image quality were compared between 5.0T and 3.0T. Results 5.0T SWI displayed vein tumor thrombi in 16 cases, except for 1 case with vein tumor thrombi in the upper segment of the left lateral lobe of the left portal vein. The liver edge score, overall image quality score, signal-to-noise ratio and contrast-to-noise ratio of portal venous phase and hepatobiliary phase in 5.0T enhanced MRI were all higher than those in 3.0T (all P<0.05). Conclusion 5.0T SWI was helpful for diagnosing HCC complicated with vein tumor thrombi. |
