目的探讨磁共振成像（MRI）在颈深部肿瘤的临床应用价值。方法收集20例疑似颈深部肿瘤作MRI检查，统计肿瘤的检出率及其对肿瘤定性的准确率，其中5例加作磁共振血管造影（MRA）。结果MRI对肿瘤的检出率为100％，对肿瘤良恶性推断准确率为95％。MRI清晰地显示出肿物的形态和毗邻关系，并清楚地显示血管的概况。结论MRI具有优越的软组织分辨力，对肿物检出率高，为肿瘤的诊断及鉴别诊断和手术设计提供客观依据。
Objective To investigate the clinical value of magnetic resonance imaging (MRI) in deep cervical tumors. Methods Twenty patients with suspected deep neck tumors were collected for MRI examination. The tumor detection rate and its accuracy for tumor characterization were calculated. Five of them were included in magnetic resonance angiography (MRA). Results The detection rate of MRI on tumors was 100%, and the accuracy of inferring benign and malignant tumors was 95%. MRI clearly shows the morphology and adjacency of the tumor and clearly shows the vascular profile. Conclusion MRI has superior soft tissue resolution and high detection rate for tumors, providing an objective basis for the diagnosis, differential diagnosis and surgical design of tumors.
