| 摘 要： | 目的观察叶内型肺隔离症的CT影像特征,分析疾病发病机理,提高影像诊断的准确率。资料与方法对16例叶内型肺隔离症患者发病部位、形态、病变周围情况、病变与血供关系等影像学表现进行回顾性分析,全部病例均采用多层螺旋CT(MSCT)平扫及增强扫描,应用多平面重组(MPR)、曲面重组(CPR)及最大密度投影(MIP)等方法进行观察。结果 16例中病变位于右下肺5例,左下肺11例。表现为大片状不均实变其间囊状透亮区8例,表现为软组织肿块影或囊实性肿块影4例,表现为单纯囊性肿块3例,仅见到异常供血动脉而肺组织未见明确异常1例。除以上表现外,异常供血区内肺组织见到肺气肿8例,支气管扩张4例。所有病例均经MPR、MIP及CPR等重组方法发现异常体动脉供血,所有体循环供血动脉均来自主动脉,供血动脉1支15例,2支1例,只有异常供血动脉及引流静脉无隔离肺肿块1例,引流静脉为肺静脉14例,引流入奇静脉2例。供血动脉分支范围在病变范围内10例,供血动脉分支范围大于病变范围6例。结论叶内型肺隔离症实质是局部肺血供的异常,体循环异常供血动脉既供应影像学表现异常的肺组织,同时也可供应其周边的影像学表现正常的肺组织;异常供血区内可见到正常、支...

| Abstract: | Objective To analyze the CT features of intralobar pulmonary sequestration and improve its diagnostic accuracy.Materials and Methods A total of 16 patients with intralobar pulmonary sequestration were analyzed retrospectively.The location,appearance,surrounding structure,the blood supply and so on were observed.All patients were examined by multi-detector spiral CT,and multiplanar reformation(MPR),curved planar reformation(CPR) and maximum intensity projection(MIP)were adopted.Results Among the 16 patients,... |
