【摘要】 目的 探討多層螺旋CT血管造影（MSCTA）對腹部巨大腫塊定位定性的診斷價值。 方法 收集2005年6月-2009年12月98例腹部巨大腫塊，作MSCTA檢查，觀察供血動脈來源和腫塊與血管關系。 結果 98例腫塊發現有主要供血動脈76例，其中惡性腫塊69例，血管受侵改變51例。 結論 由于MSCTA快捷、無創、經濟、方便、空間分辨率高等優點，對腹部巨大腫塊定位定性有較高診斷價值。【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誤診的原因,以提高對不典型肺癌的認識水平。方法:回顧性經手術、病理及細胞學檢查證實的不典型肺癌誤診病例65例的臨床及CT資料。其中胸部CT平掃20例,平掃+增強掃描45例。結果:誤診為肺結核28例,肺炎23例,慢性阻塞性肺病11例,支氣管擴張2例,肺膿腫1例。誤診時間1～11個月。結論:不典型肺癌CT表現呈多樣性,當肺部有多發病灶特別是合并基礎疾病時,容易造成誤診。反復脫落細胞檢查、及時纖支鏡檢、穿刺活檢及密切隨訪復查是減少不典型肺癌誤診的有效方法。
