摘要
规范的CT检查前处置和扫描方案的合理运用,可有效提高早期胃癌的显示能力。联合多平面重建和仿真内镜技术有助于早期胃癌的检出。CT血管成像可辅助术前对血管变异的评价和把握,有利于手术方案的制定。目前基于常规形态学的CT标准对早期胃癌的区分能力有限,结合能谱CT提高分辨率及结合相关功能影像学指标,或可成为进一步提高早期胃癌分期准确率的突破口。

Abstract
The depiction of early gastric cancer (EGC) can be improved through the proper application of standard preparation processes and scanning protocols. The combination of multiplanar reconstruction and virtual endoscopy can help the detection of EGC. CT angiography can facilitate the evaluation of variation of blood vessels and help the determination of the operation protocols. The criteria based on the conventional CT morphological modality are limited in the discrimination of EGC. The exploration of the resolution enhancement and functional indicators provided by spectral CT may provide the breakthrough for the further improvement of EGC evaluation.
