The purpose of our study has been to describe the pre-operatively MR Imaging appearance of masses in the parotid gland which may be sources of clinical and radiological confusion.
Sixty-eight adults patients with a parotid mass (39 female, 29 male) has been prospectively investigated. T1-weighted, T2-weighted, diffusion-weighted and contrast-enhanced dynamic MR images were performed by using a 1.5 or 1 T MR Imaging unit (Philips Gyroscan Intera 1.5 T. Siemens Expert 1 T). All patients underwent a parotidectomy with histopathologic analysis.
RESULTS-CONCLUSIONS: In case of pleomorphic adenoma (N=30) MR imaging sensibility, specificity and accuracy were respectively 87.5, 80.5 and 83%. In case of Warthin tumors (N=13) the same values were respectively 45.5, 93 and 85%. In case of malignant tumors (N=13) theses values were respectively 71, 89 and 87%. Our routine MR Imaging study appears excellent not only for assessing the type and extent of benign salivary gland tumors and the relationship to adjacent structures, but also for determining whether the tumor is benign or malignant.
我们研究的目的是描述腮腺肿块术前的磁共振成像（MR）表现，这些表现可能会在临床和影像学上造成混淆。
对68例腮腺肿块成年患者（39例女性，29例男性）进行了前瞻性研究。使用1.5T或1T磁共振成像设备（飞利浦Gyroscan Intera 1.5T、西门子Expert 1T）进行T1加权、T2加权、扩散加权和对比增强动态MR图像检查。所有患者均接受了腮腺切除术及组织病理学分析。
结果-结论：对于多形性腺瘤（N = 30），MR成像的敏感性、特异性和准确性分别为87.5%、80.5%和83%。对于沃辛瘤（N = 13），相同的值分别为45.5%、93%和85%。对于恶性肿瘤（N = 13），这些值分别为71%、89%和87%。我们的常规MR成像研究不仅在评估涎腺良性肿瘤的类型和范围以及与相邻结构的关系方面表现出色，而且在确定肿瘤是良性还是恶性方面也表现出色。
