目的:探讨MSCT对结肠癌诊断价值。方法:收集我院手术病理证实且经MSCT检查的结肠癌患者,对其CT表现进行分析,并与纤维结肠镜(FC),钡灌肠对比研究。结果:所有收集的结肠癌患者,MSCT均能多角度,多方法显示病变。结论: MSCT检查对结肠癌具有较高的诊断价值且对临床治疗有重大指导意义。
目的：探讨胆囊癌肝侵犯的CT诊断及临床价值。方法：回顾性分析经手术、病理证实的17例胆囊癌肝侵犯CT资料。结果：肿块型11例，腔内型2例，厚壁型4例。侵犯肝左内叶5例，肝右叶前段3例，同时侵犯肝左内叶及右叶前段9例。5例侵犯深度＜2 cm，12例侵犯深度＞2 cm。CT表现为胆囊窝脂肪间隙消失，邻近胆囊窝的肝脏组织内出现不规则形低密度影，边界模糊，胆囊癌肿与肝脏组织分界不清，增强后肝内病灶不规则强化。结论：CT对胆囊癌肝侵犯的诊断及临床分期、治疗方案的选择具有重要价值。
摘要:目的:评价64层螺旋CT对冠心病的诊断价值。方法:对25例典型病例的CT图片进行分析、总结,观察64层螺旋CT对冠状动脉的管腔狭窄程度及冠脉内斑块性质的显示能力,并对桥血管和支架通畅性进行观察。结果:近端冠脉中度以上狭窄的敏感度、准确度、阳性预测值分别为93.5%,90.3%,88.5%,对左主干及前降支病变诊断价值较高;对冠状动脉内软斑块显示较佳;对桥血管及支架通畅和有无再狭窄显示良好。结论:MSCT冠状动脉成像在冠心病筛查及冠状动脉支架术后和搭桥术后的随访发挥重要作用。Abstract: Objective: To study the diagnose value of 64slice spiral CT for coronary heart disease. Methods:The CT pictures of 25 typical cases of coronary heart disease were analyzed so as to survey the displaying ability coronal arterial stenosis, its degree and the character plaques, the patency of bypass graft and stents by 64slice spiral CT. Results:The sensitivity, accuracy, positive predictive value for RCA1 narrow above moderate was 93.5%, 90.3%, 88.5% respectively. For LM and LAD, its diagnose value was high. The coronary soft or fibrous plaque, stent and bypass graft were displayed well. Conclusion:MSCT plays an important role in filtering coronary heart disease and reexamination after stents and bypass.
