To compare the sensitivities of superparamagnetic iron oxide-enhanced and unenhanced magnetic resonance (MR) imaging at 1.5 T with those of percutaneous ultrasound (US), intraoperative US (IOUS), and dynamic computed tomography (CT) in the preoperative assessment of metastatic liver disease.
Eighteen patients with liver metastases who were candidates for curative surgery underwent presurgical imaging. Thirteen patients underwent surgery and IOUS after undergoing preoperative US, CT, and MR imaging.
In the preoperative imaging group, the standard of reference was the total number of lesions detected with any of the modalities. Superparamagnetic iron oxide-enhanced MR imaging was the most sensitive modality (99%). In the surgical group, the standard of reference was the total number of metastases identified at IOUS and pathologic examination. IOUS had the highest sensitivity (80%), followed by superparamagnetic iron oxide-enhanced MR imaging (56%).
Superparamagnetic iron oxide-enhanced high-field-strength MR imaging facilitates the preoperative evaluation of potentially curable metastatic liver disease; however, it is inferior to IOUS.
比较1.5T场强下超顺磁性氧化铁增强磁共振成像（MRI）及未增强MRI与经皮超声（US）、术中超声（IOUS）和动态计算机断层扫描（CT）在转移性肝病术前评估中的敏感性。
18例拟行根治性手术的肝转移患者术前行影像学检查。13例患者在术前行US、CT和MRI检查后接受手术及IOUS检查。
在术前成像组中，参考标准为通过任何一种检查方式检测到的病变总数。超顺磁性氧化铁增强MRI是最敏感的检查方式（99%）。在手术组中，参考标准为IOUS及病理检查发现的转移灶总数。IOUS敏感性最高（80%），其次是超顺磁性氧化铁增强MRI（56%）。
超顺磁性氧化铁增强高场强MRI有助于对潜在可治愈的转移性肝病进行术前评估；然而，其敏感性低于IOUS。
