摘要
目的探讨结肠癌在多层螺旋CT双期动态扫描中的强化表现。方法38例结肠癌患者,分为肿块型和肠壁浸润型,术前采用4层螺旋CT进行平扫和动脉期、静脉期双期增强扫描,并与术后病理结果进行对比分析。结果38例结肠癌,肿块型肿瘤动脉期肿块呈现明显强化,静脉期轻度或中度强化。肠壁浸润型静脉期强化大于动脉期限,静脉期可显示肿块周围侵犯范围要大于动脉期,T期分期较高,结果与手术病理一致。结论MSCT双期扫描可以动态显示结肠癌的强化特点、确定肿瘤的侵犯范围,对外科手术治疗提供很大的参考意义,有助于制定合理的治疗方案。
Objective To investiging the imaging characteristcs of dual-phase scans in colonic tumors. Methods 38 colonic patients were scanned by the 4-slices spial-CT. The patients were performed plan, enhancement scanned by arterial phase and venous phase, and correlated with surgical as well as pathologic findings were compared and analyzed. Results The colonic tumors in 38 cases were enhanced obviously in the arterial phase and slightly enhance in the venous phase. The average enhance scope in venous phase are bigger than that of arterial phase. Conclusion Spiral CT can clearly display sites, thickness, extension, and complications of hematoma. MSCT can be used as the first means in the diagnosis and follow-up of AAD.
