Abstract

Five patients with a diagnosis of rectal carcinoma were examined by magnetic resonance and computerized tomography (CT) to determine if magnetic resonance imaging (MRI) added any information to that obtained by computerized tomography. In each case, the imaging studies agreed with the surgical description of the tumor. The studies agreed on the presence of perirectal fat invasion and tumor position. Both modalities were positive for involved lymph nodes in the patient with metastatic disease to pelvic nodes, but both studies underestimated the number of nodes involved. These five cases were examined using two magnetic resonance scanners. The older one operated at 0.3 tesla (T) while the newer scanner operated at 1 T. Spatial resolution was improved with the newer scanner. In addition, the difference in signal intensity between tumor tissue and normal tissue was greater on the 1 T scanner. Tissue differentiation was useful in one case in which CT suggested extension of tumor into the vagina. The extension was confirmed on the MRI scan.

摘要

对5例诊断为直肠癌的患者进行了磁共振成像（MRI）和计算机断层扫描（CT）检查，以确定MRI是否能提供比CT更多的信息。在每例患者中，影像学检查结果与手术中对肿瘤的描述一致。两项检查在直肠周围脂肪浸润情况和肿瘤位置方面的结果相符。对于盆腔淋巴结转移的患者，两种检查方法对受累淋巴结的判断均为阳性，但二者均低估了受累淋巴结的数量。这5例患者使用了两台磁共振扫描仪进行检查。较旧的一台磁场强度为0.3特斯拉（T），较新的一台磁场强度为1 T。较新的扫描仪提高了空间分辨率。此外，在1 T扫描仪上，肿瘤组织与正常组织之间的信号强度差异更大。在1例CT提示肿瘤侵犯阴道的病例中，组织分化情况有助于明确诊断，MRI扫描证实了肿瘤的侵犯。
