目的:重点探索3.0TMR动态增强扫描结合弥散成像在小肝癌患者中的诊断价值。方法:选取的研究对象是2011年1月-2013年12月在我院接受治疗的30例小肝癌患者,分析这些患者的弥散成像资料、动态增强检察资料、MR平扫资料,对比检查结果。结果:对30例患者进行平扫,结果发现39个病灶。病灶的直径最长达到3 cm,病灶的直径最短为3.0 cm,病灶的平均直径为1.69 cm。动态增强扫描结果显示的病灶总共有41处,其中速升速降型总共有25个病灶、持续强化型总共有6个病灶、缓升速降型总共有5个病灶、无明显强化型总共有5个病灶。DWI诊断小肝癌病灶的ADC值达到(0.815±0.173)×10~(-3)mm~2/s,DWI诊断病灶四周正常肝组织的ADC值达到(1.886±0.314)×10~(-3)mm~2/s,两个ADC值具有明显的差别(P<0.05)。结论:3.0TMR动态增强扫描结合弥散成像在小肝癌患者的诊断中诊断准确性较高,值得推荐。
Objective: To explore the diagnostic value of 3.0T MR dynamic contrast-enhanced radiography combined with diffusion imaging in patients with small hepatocellular carcinoma. Methods: Thirty patients with small hepatocellular carcinoma who were treated in our hospital from January 2011 to December 2013 were enrolled in this study. Diffusion imaging data, dynamically enhanced screening data, MR plain scan data were compared between the two groups. Results: Thirty patients were scanned plainly, and 39 lesions were found. The longest diameter of the lesion reached 3 cm, the shortest diameter of the lesion was 3.0 cm, and the average diameter of the lesion was 1.69 cm. Dynamic enhanced scan results showed a total of 41 lesions, of which the rate of ascending-speed reduction of a total of 25 lesions, continuous enhancement of a total of 6 lesions, slow-down slow-down a total of 5 lesions, no significant enhancement of the total 5 lesions. The ADC value of DWI was 0.815 ± 0.173 × 10 ~ (-3) mm ~ 2 / s for diagnosis of small hepatocellular carcinoma and 1.886 ± 0.314 × 10 -3 for DWI. mm ~ 2 / s, there is a significant difference between the two ADC values (P <0.05). Conclusion: 3.0T MR dynamic enhanced scan combined with diffusion imaging in the diagnosis of small hepatocellular carcinoma in patients with high diagnostic accuracy, it is recommended.
