CT扫描技术在贲门癌诊断中的应用

分析３８例贲门癌双期增强动态ＣＴ扫描的影像表现，并与手术、病理进行对比，进一步评价动态ＣＴ扫描对肿瘤检出及ＴＮＭ分期的价值。结果显示早期、进展期贲门癌检出率分别为 ８０．０％和 ９３．９％。ＴＮＭ分期准确率８１．６％，贲门癌可切除准确率８９．７％。贲门癌主要ＣＴ表现是胃壁局限或广泛增厚，增强早期胃癌呈不均匀强化。提示双期增强动态ＣＴ扫描对贲门癌诊断有意义，以增强早期效果好。在选择治疗方案时，提供有益信息。

CT Features of Cardiac Carcinoma and Its Diagnostic Values

To analyze two-phase dynamic CT features of 38 cases with cardiac carcinoma and to assess its usefulness for tumor detection and stages compared with surgical and pathologic findings. The detectablity of two-phase enhanced CT scanning for early and advanced cardiac carcinoma was 80% and 93.3% respectively. The accuracy of TNM stages and predicted surgery was 81.6% and 89.7% respectively. The manifestation of cardiac carcinoma included local or extensive thickening of gastric wall shown moderate or marked heterogeneous enhancement in the first phase (early enhancing phase). However, they shown homogeneous enhancement in the second phase. The results suggest that enhanced dynamic CT scan plays significant role in the diagnosis of cardiac carcinoma. the early enhancing phase scan demonstrates the tumor lesions. and it offers helpful information for selecting the method of therapy.
