Twenty patients with surgically proved neoplasms of the parotid gland were evaluated in order to compare contrast material-enhanced computed tomography (CT) and magnetic resonance (MR) imaging. In 14 patients both CT and MR imaging examinations were performed, while in six only MR imaging was performed. Because contrast resolution is better with MR imaging, it appears to be superior to CT in distinguishing the parotid gland from surrounding structures. Four intraparotid lesions were more conspicuous on T2-weighted MR images than on CT scans. MR imaging appears to be superior to CT for evaluating parotid masses and for distinguishing neoplasms of the parotid gland from those originating within the parapharyngeal space.
为了比较对比剂增强计算机断层扫描（CT）和磁共振（MR）成像，对20例经手术证实患有腮腺肿瘤的患者进行了评估。14例患者同时进行了CT和MR成像检查，6例仅进行了MR成像检查。由于MR成像的对比分辨率更高，在区分腮腺与周围结构方面似乎优于CT。4例腮腺内病变在T2加权MR图像上比在CT扫描上更明显。MR成像在评估腮腺肿块以及区分腮腺肿瘤与起源于咽旁间隙的肿瘤方面似乎优于CT。
