Twenty-five patients with nonseminomatous germ cell carcinoma of the testis underwent CT and nuclear magnetic resonance (NMR) of the retroperitoneum followed by radical retroperitoneal lymph node dissection for surgical proof of metastatic disease. Computed tomography correctly predicted the presence or absence of adenopathy in 88% and assigned the correct stage in 84%. Nuclear magnetic resonance had comparable figures of 84 and 80%. Computed tomography appeared superior to NMR in detecting other abdominal abnormalities, although these were few in number. Nuclear magnetic resonance is nearly equivalent to CT in staging retroperitoneal lymphadenopathy from testicular cancer and may surpass CT following technical advances and the introduction of oral contrast agents.
25例睾丸非精原细胞瘤患者接受了腹膜后CT和核磁共振（NMR）检查，随后进行了根治性腹膜后淋巴结清扫术，以获得转移性疾病的手术证据。计算机断层扫描正确预测淋巴结病存在与否的准确率为88%，正确分期的准确率为84%。核磁共振的相应数字分别为84%和80%。在检测其他腹部异常方面，计算机断层扫描似乎优于核磁共振，尽管此类异常数量较少。在对睾丸癌腹膜后淋巴结进行分期方面，核磁共振与CT几乎相当，随着技术进步和口服造影剂的引入，核磁共振可能会超过CT。
