对２３例腮腺肿块进行了ＭＲＩ扫描，部份病例同时作了Ｂ超、造影及ＣＴ，并追踪术后病检．结果表明：①ＭＲＩ对腮腺具有较ＣＴ更强的组织分辨力，能显示腺内主要的神经、血管．②能准确判定腺内有无占位性病变．③能准确判定腺内、外肿瘤．④立体成像，能多方位观察肿瘤位置、范围及周围组织关系．恶性肿瘤可了解颈部转移情况，有助于指导临床分期、治疗及预后估计．⑤根据形态及边界特点，能判断大多数肿瘤的良恶性，但两者的Ｔ１，Ｔ２信号变化无特异性．⑥腮腺非肿瘤性病变的Ｔ１，Ｔ２信号变化无特异性，不如常规Ｘ线造影．
Twenty-three cases of parotid gland masses were scanned by MRI. In some cases, B-mode ultrasound, CT and CT were performed at the same time. The results showed that: ① MRI of the parotid gland than CT has a stronger tissue resolution, can show the main glandular nerves and blood vessels. ② can accurately determine the presence of gland lesions. ③ can accurately determine the gland, outside the tumor. ④ three-dimensional imaging, multi-directional observation of tumor location, scope and the surrounding tissue. Malignant tumor can understand the situation of neck metastasis, help to guide the clinical stage, treatment and prognosis. ⑤ According to the morphology and the characteristics of the border, most of the tumors can be judged benign and malignant, but the two T1 and T2 signal changes without specificity. ⑥ parotid non-neoplastic lesions T1, T2 signal changes without specificity, as conventional radiography.
