Magnetic resonance (MR) imaging has quickly emerged and already replaced computerized tomography (CT) in the evaluation of cerebellopontine angle (CPA) lesions, although even MR scanning may occasionally yield equivocal results. We recently studied six patients with a new MR image-enhancing contrast, gadolinium-DTPA (Gd-DTPA). All patients were suspected of having CPA pathology, and the standard MR scan was either negative, equivocal, or left unanswered questions regarding confirmed lesions. The Gd-DTPA-enhanced MR scan confirmed tumors or added useful information in five of six patients.
磁共振（MR）成像已迅速兴起，在桥小脑角（CPA）病变评估中已取代计算机断层扫描（CT），尽管即使是MR扫描偶尔也可能产生模棱两可的结果。我们最近对6例患者使用了一种新的MR图像增强造影剂钆-二乙三胺五醋酸（Gd-DTPA）进行研究。所有患者均怀疑患有CPA病变，标准MR扫描结果要么为阴性、模棱两可，要么对于已确诊的病变仍存在未解答的问题。Gd-DTPA增强MR扫描在6例患者中的5例中确诊了肿瘤或提供了有用信息。
