目的：探讨肝脏小结节病变的磁共振(MRI)不同表现在诊断与鉴别诊断中的价值。方法：选取2008年1月至2012年8月经黑龙江省医院临床证实的直径≤3 cm肝脏小结节病变的76例患者，采用美国GE公司双梯度Signa3.0T HD MRI，先行平扫，通过注射钆喷酸葡胺进行增强扫描，分析肝脏结节的MRI表现。结果：各种疾病在MRI的T1WI和T2WI表现上各有特点，加之钆剂增强不同的强化特点，对肝脏小结节病变基本可以给出正确的诊断，经MRI诊断出原发肝细胞癌(HCC)15例，转移癌12例，再生性结节(RN)40例，肝细胞腺瘤(HAC)6例，局灶性结节样增生(FNH)3例。其中，原发肝细胞癌和转移癌与病理验证相符。结论：MRI平扫、多期增强扫描对肝脏小结节病变的诊断与鉴别诊断价值较高。

Objective:To study the imaging features and differential diagnosis by MRI in liver small hepatic nodules. Methods:Confirmed by clinical the hepatic small nodulars of diameter≤3cm in 76 cases in our hospital during January 2008-August 2012. The USA GE dual gradient Signa 3.0T HD MRI was used to first scan and be enhanced scanning and performed by injection of gadopentetate dimeglumine and analyse MRI findings of the liver hepatic nodules. Results:Because all kinds of diseases have their own characteristics in the T1WI and T2WI of MRI and GD DTPA enhancement of different enhancement features, a correct diagnosis can be given for the liver small nodulars. Diagnosis by MRI is 15 cases of carcinoma(HCC), 12 of metastatic carcinoma, 40 of regenerative nodules (RN), 6 of hepatocellular adenoma (HAC), 3 of focal nodular hyperplasia(FNH). Conclusion:Correct imaging diagnosis is possible in liver small nodules by plain and multi-phase enhanced scan MRI, and it is of great value in differential diagnosis.
