| 目的 探讨3.0T磁共振扩散加权成像(DWI)在肝脏良恶性病变诊断中的应用价值。 方法 收集35例肝脏占位患者,对患者进行DWI 扫描。 结果 肝细胞癌、肝转移瘤DWI均呈高信号,测得表观弥散系数(ADC)较低,分别为(1.00±0.19)×10-3 mm2/s和(1.16±0.34)×10-3 mm2/s,肝囊肿DWI呈高、等或低信号,肝血管瘤DWI呈稍高信号,测得ADC值均较高,分别为(3.36±0.79)×10-3 mm2/s和(1.99±0.14)×10-3 mm2/s,统计发现:DWI 扫描对肝脏良恶性鉴别差异有统计学意义(P＜0.05)。 结论 DWI 扫描对肝脏良恶性病变的诊断具有明显优势。 |

| Objective To explore the application value of 3.0T magnetic resonance DWI in the diagnosis of benign and malignant liver lesions. Methods Thirty-five cases with liver masses were collected and performed by DWI scan. Results DWI values of hepatocellular carcinoma (HCC) and liver metastatic tumors displayed hyperintense,and the apparent diffusion coefficient were low,the value was (1.00±0.19)×10-3 mm2/s and (1.16±0.34)×10-3 mm2/s,respectively.DWI value of liver cyst showed low signal,signal or high signal.The DWI of hepatic hemangioma was slightly higher.The apparent diffusion coefficient was (3.36±0.79)×10-3 mm2/s and (1.99±0.14)×10-3 mm2/s,respectively.Statistical findings:DWI scanning showed statistically significant difference in differentiating between malignant and benign liver leisions. Conclusion DWI scan has obvious advantages in the diagnosis of benign and malignant liver lesions,which can improve the diagnosis rate of hepatic lesions. |
