【摘要】 目的　评价磁共振成像 (MRI)导引肝脏穿刺活检的临床应用价值。方法　应用常规 0 5TMRI扫描机对 13例病人作MRI导引经皮肝穿刺活检 ,用 19GMRI兼容的抽吸穿刺针作穿刺。采用快速梯度回波和快速自旋回波技术扫描。结果　MR导引经皮肝穿刺均获成功 ,未出现任何并发症。刺中率为 10 0 % ,活检正确率为 92 3% ,假阴性率 7 7%。结论　MRI导引经皮肝穿刺活检是一种安全、正确有效的诊断和鉴别诊断方法更多还原

【Abstract】 Objective To evaluate the clinical application of MR guided aspiration biopsy of liver lesions. Methods MR guided aspiration biopsy of liver lesions with 0.5T Conventional MR system and 19 gauge MRI compatible aspiration needle was performed in 13 patients. For MR guidance,fast gradient echo sequence or fast spin echo sequence was used. Results MR guided aspiration liver biopsy was performed successfully without any complication on all patients. The accurate needle puncture rate was 100%, accurate diagnosis rate 92.3%,and false negative rate 7.7%. Conclusion MR guided transcutaneous aspiration biopsy of liver lesions is a safe,accurate and effective method for diagnosis and differential diagnosis.更多还原
