【摘要】 目的 探讨多层螺旋CT血管造影（MSCTA）对腹部巨大肿块定位定性的诊断价值。 方法 收集2005年6月-2009年12月98例腹部巨大肿块，作MSCTA检查，观察供血动脉来源和肿块与血管关系。 结果 98例肿块发现有主要供血动脉76例，其中恶性肿块69例，血管受侵改变51例。 结论 由于MSCTA快捷、无创、经济、方便、空间分辨率高等优点，对腹部巨大肿块定位定性有较高诊断价值。【Abstract】 Objective To investigate the diagnostic value of multislice CT angiography (MSCTA) to abdominal huge mass from June 2005 to December 2009. The relation among blood vessel and supply origin and tumor was analyzed. Methods MSCTA was performed in 98 cases with abdomenial huge mass. Results The feeding artery of mass was discovered in 76 cases, in which malignant tumors were confirmed in 69 cases, the vessels were encroached on in 51 cases. Conclusion MSCTA may be of high value to diagnose abdominal huge mass because of noninvasiveness, convenience, and high resolution.
目的:分析不典型肺癌CT误诊的原因,以提高对不典型肺癌的认识水平。方法:回顾性经手术、病理及细胞学检查证实的不典型肺癌误诊病例65例的临床及CT资料。其中胸部CT平扫20例,平扫+增强扫描45例。结果:误诊为肺结核28例,肺炎23例,慢性阻塞性肺病11例,支气管扩张2例,肺脓肿1例。误诊时间1～11个月。结论:不典型肺癌CT表现呈多样性,当肺部有多发病灶特别是合并基础疾病时,容易造成误诊。反复脱落细胞检查、及时纤支镜检、穿刺活检及密切随访复查是减少不典型肺癌误诊的有效方法。
