16层螺旋CT三维及多平面重建在儿童头颈部血管瘤的应用

Application of 16 MSCT in Diagnosis of Angioma of Head and Cervix in Children

目的探讨多层螺旋CT(MSCT)三维(3D)多平面重建(MPR)技术显示儿童头颈部血管瘤的价值。资料与方法搜集MSCT增强扫描的头颈部血管瘤患儿22例进行回顾性分析,观察肿瘤外形、肿瘤血管、供血及回流血管、与颅内有无交通。结果血管瘤呈均匀或不均匀强化,3DMPR清晰显示了22例血管瘤的位置、形态、大小、范围以及与周围组织的关系,其中供血动脉及回流静脉清晰显示16例,未显示者2例,回流静脉血管显示而供血动脉未显示者4例。2例血管瘤引流血管与颅内血管及血窦相通,余20例血管瘤与颅内无交通。结论MSCT3DMPR技术对于血管瘤的定位,显示其大小、范围、供血和回流血管、是否与颅内相沟通等方面具有优势。是观察头颈部血管瘤的首选方法。

Objective To discuss the value of MSCT 3D and MPR in diagnosis of angioma of head and cervix in children. Materials and Methods 22 cases with angiomas in head and cervical examined by 16MSCT enhanced CT scan were analyzed respectively, and to observe the shape, in and out vessels of angioma, relation between the angioma and encephalic structure. Resuits 22 cases were manifested as homogeneous or inhomogeneous enhancement, the angioma＇s location, shape, size, range, relation with surrounding structure, supplying and drainage vessels were displayed in 16 cases, not displayed in 2 cases, supplying vessel not be displayed and draining vein displayed in 4 cases by 3D MPR. 20 cases had no relationship with encephalic structure, 2 cases had vessels between the angioma and encephulic blood sinus or vessel. Conclusion MSCT 3D and MPR have advantage in showing the shape, location, in and out vessels of angioma, relation between the angioma and encephalic structure, it is a first choice to diagnose angioma of head and cervix.
