观察3.0TMR动态增强扫描及弥散成像联合应用诊断小肝癌的影像价值

Imaging Diagnostic Value of Combined 3.0 TMR Dynamic Contrast-enhanced Scan and Diffusion Weighted Imaging for Small Hepatocellular Carcinoma

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 diagnostic value of combined 3.0 TMR dynamic contrast-enhanced scan （DCE-MRI） and diffusion weighted imaging （DWI） for small hepatocellular carcinoma （SHCC）. Methods： 30 patients of SHCC treated in our hospital from 2011 January to 2013 December were selected. We analyzed data of the patients of DWI, DCE-MRI and MR and compared the results. Results： We scanned the 30 patients and we found 39 lesions. The lesion diameter ranged from 3 cm to 3 cm with an average of 1.69cm. DCE-MRI showed that there were 41 lesions, with 25 lesions of quick-rising-quick-declining type, 6 lesions of sustained-enhancing type, 5 lesions of slow-rising-quick-declining type and 5 lesions of no-significant-enhancing type. DWI showed lesions＇ ADC scores reached （0.815±0.173） ×10^-3mm2/s while the scores of normal tissues around lesions reached （1.886±0.314）×10^-3mm2/s, with significant difference （P〈0.05）. Conclusion： Combined 3.0 TMR DCE-MRI and DWI shows high diagnostic accuracy which is worthy of promotion.
