AIMS
To compare the clinical utility of contrast enhanced magnetic resonance imaging (MRI) to ultrasound (USS) and computed tomography (CT) in focal hepatic lesions (FHLs)
METHODS
This retrospective study analysed 125 consecutive iron oxide enhanced (SPIO) MRI.
RESULTS
MRI made a difference in 74% of patients who had USS and in 42% of patients who had a CT scan. In suspected cancer, MRI changed diagnosis in 58% and 37% (13/35), respectively.
CONCLUSIONS
MRI is superior to other noninvasive imaging modalities for lesion identification and characterisation.
目的
比较对比增强磁共振成像（MRI）与超声（USS）及计算机断层扫描（CT）在肝脏局灶性病变（FHLs）中的临床应用价值。
方法
这项回顾性研究分析了连续125例接受超顺磁性氧化铁增强（SPIO）MRI检查的患者。
结果
MRI对74%接受USS检查的患者以及42%接受CT扫描的患者的诊断产生了影响。在疑似癌症患者中，MRI分别使58%（13/23）和37%（13/35）的患者诊断发生改变。
结论
在病变识别和特征描述方面，MRI优于其他非侵入性成像方式。
