摘 要: | 目的探讨磁共振扩散加权成像在肝脏肿瘤性病变中的诊断价值。 方法对180肝脏肿瘤进行常规MRI平扫和扩散加权成像,表观扩散系数(b值)分别为0 s/mm2和1000 s/mm2,测量病变的表面扩散系数(ADC)值,65肝脏肿瘤同时进行了多期增强扫描。 结果肝癌、肝脏转移瘤患者病变区的ADC值分别为(1.12±0.23)×10-3 mm2/s、(1.51±0.43)×10-3mm2/s;肝囊肿、肝脏血管瘤患者病变区的ADC值分别为(2.43±0.68)×10-3 mm2/s、(1.99±0.78)×10-3 mm2/s;肝脏良性病变与恶性病变区域内的ADC值差异有统计学意义(P < 0.05)。 结论磁共振弥散成像对肝脏肿瘤的诊断具有很大的价值,特别是对肝脏良恶性的鉴别诊断有一定的价值。

Abstract: | Objective DWI lesions in the liver tumor diagnosis. Methods A total of 180 cases of liver tumors unenhanced routine MRI and diffusion-weighted imaging, apparent diffusion coefficient (b value) were 0 s/mm2 and 1000 s/mm2, measurement of lesions on the surface diffusion coefficient (ADC) values, 65 patients with liver tumors simultaneous multi-phase scan. Results Liver cancer, liver metastases in patients with lesions of the ADC values were (1.12±0.23)×10-3 mm2/s, (1.51±0.43)×10-3 mm2 /s; liver cyst, liver lesions in patients with vascular tumors ADC values were (2.43±0.68)×10-3 mm2/s, (1.99±0.78)×10-3 mm2/s; benign and malignant liver lesions in the region ADC values were significantly (P < 0.05). Conclusion MR diffusion imaging diagnosis of liver tumors of great value, especially for the differential diagnosis of benign and malignant liver has a certain value. |
