Pathological lesions of the parotid gland were examined comparatively with different examination sequences both plain and with the contrast medium Gd-DTPA. There were 36 benign lesions (parotitis, Sjögren's syndrome, adenoma, etc.) and 24 malignant tumours (squamous cell carcinoma, adenocarcinoma, adenoid cystic carcinoma etc.) Examinations were carried out at 1.0 T with long and short spin echo sequences in transverse and frontal layer orientation before and after application of Gd-DTPA as contrast medium. In the patients suffering from parotitis the best results were obtained with plain T1 and T2 sequences; the contrast medium Gd-DTPA remained without superior diagnostic relevance. However, in Sjögren's syndrome (myoepithelial sialadenitis) administration of the contrast medium always yielded a characteristic honeycomblike pattern. In benign and malignant space-occupying growths MRI supplied additional diagnostic information with Gd-DTPA in respect of defining the tumour borderlines and paths of infiltration. MRI is now a significant diagnostic tool in inflammatory and tumorous lesions of the parotid gland.
采用不同的检查序列（平扫及使用钆喷酸葡胺造影剂）对腮腺的病理损害进行了对比检查。共有36例良性病变（腮腺炎、干燥综合征、腺瘤等）和24例恶性肿瘤（鳞状细胞癌、腺癌、腺样囊性癌等）。以钆喷酸葡胺作为造影剂，在1.0 T磁场下，于应用造影剂前后，采用长、短自旋回波序列，在横断面和冠状面进行检查。对于患腮腺炎的患者，平扫T1和T2序列的检查结果最佳；钆喷酸葡胺造影剂并无更高的诊断价值。然而，在干燥综合征（肌上皮涎腺炎）中，使用造影剂总能产生特征性的蜂窝状图像。对于良性和恶性占位性病变，MRI在使用钆喷酸葡胺时，在界定肿瘤边界和浸润路径方面提供了额外的诊断信息。MRI现在是腮腺炎性和肿瘤性病变的一种重要诊断工具。
