Dynamic magnetic resonance imaging (MRI) was performed in two patients with hepatic tumors (one cavernous hemangioma and one hepatoma). A sequential timed scanning technique with spin echo images (TR: 100 msec; TE: 20 msec; data acquisition time: 26 sec) was used with a bolus injection of 0.05 mmol/kg gadolinium DTPA. Dynamic MRI findings in the two cases were similar to those obtained with dynamic CT and angiography using iodinated contrast medium. Our early experience suggested that the less invasive technique of dynamic MRI could replace conventional dynamic CT in assessing the hemodynamics of hepatic tumors.
对两名患有肝脏肿瘤(一名为海绵状血管瘤,一名为肝癌)的患者进行了动态磁共振成像(MRI)检查。采用自旋回波图像的顺序定时扫描技术(重复时间:100毫秒;回波时间:20毫秒;数据采集时间:26秒),并团注0.05毫摩尔/千克的钆喷酸葡胺。这两例患者的动态MRI表现与使用碘化造影剂的动态CT及血管造影检查结果相似。我们早期的经验表明,在评估肝脏肿瘤血流动力学方面,侵入性较小的动态MRI技术可以取代传统的动态CT。
