OBJECTIVE
The objective of this study was to demonstrate the usefulness of high-resolution three-dimensional (3D) constructive interference in steady-state (CISS) MR imaging for evaluating mural invasion and the morphologic features of gastric cancers in vitro.
MATERIALS AND METHODS
High-resolution 3D-CISS MR images were obtained in three surgical specimens containing three different gastric cancers.
RESULTS
In early carcinoma, advanced carcinoma, and leiomyosarcoma, the depth of mural invasion at 3D-CISS MR imaging correlated well with the histopathologic stage.
CONCLUSION
High-resolution 3D-CISS MR imaging is a useful method for evaluating mural invasion and the macroscopic features of gastric cancers in vitro.
目的
本研究的目的是证明高分辨率三维稳态构成干扰序列（CISS）磁共振成像在体外评估胃癌壁内侵犯及形态学特征方面的实用性。
材料与方法
对包含三种不同胃癌的三个手术标本进行高分辨率三维CISS磁共振成像。
结果
在早期癌、进展期癌和平滑肌肉瘤中，三维CISS磁共振成像显示的壁内侵犯深度与组织病理学分期密切相关。
结论
高分辨率三维CISS磁共振成像是体外评估胃癌壁内侵犯及大体特征的一种有用方法。
