目的：探讨磁共振成像（MR）在预测颈动脉周围头颈部肿瘤可切除性中的价值。材料与方法：49例有头颈部肿块和颈动脉壁侵犯临床证据的患者行MR成像，其中男性28例，女性21例，年龄17-79岁，平均57.3岁。分析t1加权、t2加权和钆增强t1加权图像，以确定53条动脉被肿瘤累及。结果：超过270度的周向累及被认为提示恶性肿瘤不可切除；270度或更小被认为没有入侵。MR影像学诊断不可切除病变的敏感性为100%（12例中的12例），特异性为88%（41例中的36例），准确性为91%（53例中的48例）。鳞状细胞癌的准确率为100% （n = 29）。结论：肿瘤包含颈动脉270度以上可能无法从动脉中切除。累及动脉270度以下的肿瘤可以切除。
PURPOSE: To determine the value of magnetic resonance (MR) imaging in predicting resectability of head and neck neoplasms around the carotid arteries.MATERIALS AND METHODS: Forty-nine patients (28 male patients and 21 female patients aged 17-79 years; mean, 57.3 years) with head and neck masses and clinical evidence of carotid wall invasion underwent MR imaging. T1-weighted, T2-weighted, and gadolinium-enhanced T1-weighted images were analyzed to determine circumferential involvement of 53 arteries by tumor.RESULTS: More than 270 degrees of circumferential involvement was considered suggestive of unresectability of the malignant neoplasm; 270 degrees or less was considered lack of invasion. The sensitivity of MR imaging for determination of unresectable disease was 100% (12 of 12 cases), specificity was 88% (36 of 41), and accuracy was 91% (48 of 53). Accuracy was 100% for squamous cell carcinoma (n = 29).CONCLUSION: Tumor that encompasses more than 270 degrees of the carotid artery probably cannot be removed from the artery. Tumor that involves 270 degrees or less of the artery can be removed.
