摘　　要：目的:探讨64层螺旋CT血管成像(CTA)对明确颈部包块与周围血管关系的价值。方法:采用GE LightSpeed6 4层螺旋CT对25例颈部包块患者行颈部平扫及增强扫描,将获得的原始数据传入ADW4.3后处理工作站,血管重建技术选择容积重建(VR),诊断采用VR与轴位图像相结合的方式。结果:淋巴性病变10例,包括淋巴结结核2例、淋巴结转移4例、淋巴瘤4例,非淋巴性病变15例,包括淋巴管瘤1例、腮腺混合瘤2例、甲状腺癌4例、甲状腺腺瘤3例、孤立性纤维瘤1例、蔓状血管瘤2例、表皮样囊肿1例、咽旁脓肿1例。包块位于气管两侧6例,左侧15例,右侧4例;位于甲状腺内7例,腮腺内2例,颈动脉间隙11例,1例位于咽旁,其余4例位于颈部表浅组织内;颈部包块致毗邻血管移位、变形9例,其中动脉7例、静脉2例;颈部包块侵袭及包绕血管3例,包括动脉1例、静脉2例,其中1例静脉内血栓形成;颈部包块与血管关系密切2例;颈动脉发出分支供应颈部包块1例;其余10例与颈部血管无明显关系。结论:64层螺旋CTA容积重建结合轴位图像,可较准确地明确颈部包块与血管之间的关系。Objective： To explore the the value of axial view and volume rendering image in identify the relationship of tumor and blood vessel in cervical part with 64-slice MSCT angiography.clinical suspicious artherosclerosis in Methods： CT plain scan and enhancement scanning was performed in 25 patients with tumor of cervical part, by a GE LightSpeed 64-slice MSCT scanner. Then the row date was transmitted the AW 4.3P work station, Source images were processed by post-processing softwarethe VR techniques,diagnosis was obtained by tow doctors combine with VR and axial view image. Results： There are 11 patients with lymphoid lesions, including 2 crewels, 4 lymph node metastasis and 4 lymphadenoma; 15 patients with non-lymphoid lesions, including 1 angiolymphoma, 2 mixed tumor of parotid gland,4 struma maligna, 3 thyroid adenoma, 1 isolate fibroid, 2 angioma arteriale racemosu, 1 epidermoid cyst, 1 parapharyngeal abscess; The location of tumors： 6 cases were located on both sides of the trachea; 15,on the left;4 ,on the right.7 cases were located in the thyroid gland;2 ,in the parotid gland,11 ,in the carotid space;1, in the parapharyngeal. Cervical tumors of 9 casess led to adjacent blood vessels displacement and deformation, including 7 arteries and 2 veins.There were 3 casess of cervical blood vessels invaded and surrounded by cervical tumors, including 1 arteries and 2 veins（1 vein thrombosis）. There were no close relationship between cervical tumor and blood vessels in most cases,but in 2 cases. Conclusions： 64-slice MSCT angiography can accurately confirm the relationship between cervical tumor and blood vessels.
