目的：探讨磁共振动态增强检查和水分子扩散加权成像（DWI）在肝结节性病变与小肝癌诊断及鉴别诊断的价值及局限性，对比研究两种检查方法对肝脏占位性病变的检出效能。方法：收集125例肝脏占位性病变患者共172个病灶，常规MRI 平扫、LAVA 增强及 DWI 检查（b 值分别为0和500 s/ mm2），对比分析 LAVA 三期扫描（A 组）、DWI（B 组）及这两种方法联合应用（C 组）在肝结节病及小肝癌检出和定性的诊断价值。结果：在结节检出方面：A 组检出146个结节，B 组检出138个，C 组检出172个，三组组间比较差异有统计学意义（χ2＝35.756，P <0.01）。在结节的定性诊断方面：在取得临床或病理证实的116个病例中，A 组诊断正确82例（70.7%），B 组诊断正确76例（65.5%），C 组为108例（93.1%），三组组间比较差异有统计学意义（A组与 C 组对比χ2＝19.653，P <0.01；B 组与 C 组对比χ2＝21.274，P <0.01）。结论：动态增强扫描联合 DWI 有助于提高肝脏结节性病变的检出率，增加诊断信息，提高诊断正确率。
目的：探討磁共振動態增彊檢查和水分子擴散加權成像（DWI）在肝結節性病變與小肝癌診斷及鑒彆診斷的價值及跼限性，對比研究兩種檢查方法對肝髒佔位性病變的檢齣效能。方法：收集125例肝髒佔位性病變患者共172箇病竈，常規MRI 平掃、LAVA 增彊及 DWI 檢查（b 值分彆為0和500 s/ mm2），對比分析 LAVA 三期掃描（A 組）、DWI（B 組）及這兩種方法聯閤應用（C 組）在肝結節病及小肝癌檢齣和定性的診斷價值。結果：在結節檢齣方麵：A 組檢齣146箇結節，B 組檢齣138箇，C 組檢齣172箇，三組組間比較差異有統計學意義（χ2＝35.756，P <0.01）。在結節的定性診斷方麵：在取得臨床或病理證實的116箇病例中，A 組診斷正確82例（70.7%），B 組診斷正確76例（65.5%），C 組為108例（93.1%），三組組間比較差異有統計學意義（A組與 C 組對比χ2＝19.653，P <0.01；B 組與 C 組對比χ2＝21.274，P <0.01）。結論：動態增彊掃描聯閤 DWI 有助于提高肝髒結節性病變的檢齣率，增加診斷信息，提高診斷正確率。

Objective To study the value in diagnosis and differential diagnosis of MRI dynamic enhanced and DWI in the diagnosis of intrahepatic nodular lesions and small liver carcinoma,comparative study the detection efficacy of the two examine. Methods Collected 125 patientS with Intrahepatic occupying lesion with total 172 focal hepatic lesions were examined by routine conventional and dynamic en-hanced MRI incombination with DWI(SE/ EPI technique,b value as 0 and 500s/ mm2 respectively). The values of detection and diagnosis of Intrahepatic nodular lesions and small liver carcinoma by dynamic enhanced MRI(groupA),DWI(groupB)and dynamic enhanced MRI in combination with DWI(groupC)were comparedandanalyzed. Results In the respect of detecting intra - hepatic small nodular lesions,146 intra - hepatic small nodular lesions were detected by(groupA),138 lesions by(groupB)and 172 lesions by(groupC),significant statistical differences were existed(χ2 = 35. 756,P < 0. 01). Inthe respect of qualitative diagnosis of intra - hepatic small nodular lesions,there were 116 clinical or pathology proved nodular lesions,correct diagnosis was obtained in 82 cases(70. 7% )by(groupA),76cases(65. 5% )by (group B),108 cases(93. 1% )by(group C),with significant statistica1 difference(group A)compared with(group C)χ2 = 19. 653,P <0. 01;(group B)compared with(group C)χ2 = 21. 274,P < 0. 01). Conclusion DWI in combination with LAVA dynamic enhanced addable diagnostic information,raise correct rate in diagnosis.
