影像检查在胃肠道间质瘤诊断及危险度分级中的应用进展

Application of imaging diagnosis in the diagnosis and risk grading of gastrointestinal stromal tumors

胃肠道间质瘤(gastrointestinal stromal tumor,GIST)是消化系统常见的间叶性肿瘤,具有恶性潜能,学者们根据其危险程度提出了GIST的危险度分级。影像检查在评估GIST危险程度上具有重要的意义,胃充盈超声、内镜超声(endoscopic ultrasonography,EUS)、X线钡餐、计算机断层成像(computed tomography,CT)、核磁共振成像(magnetic resonance imaging,MRI)等影像学技术均可用于GIST危险程度分级。然而,不同的影像学检查方法各有优缺点,如何利用影像学手段在术前精准评估GIST的危险程度仍需进一步研究。本文对影像检查在胃肠道间质瘤危险度分级中的应用进展做一综述,以期为临床诊疗提供借鉴和参考。

Gastrointestinal stromal tumor(GIST)is a common mesenchymal tumor of the digestive system.Because of its malig⁃nant potential,scholars have proposed risk classification of GIST according to its risk degree.Imaging examination plays an important role in evaluating the classification of GIST risk degree.Imaging techniques such as gastric filling ultrasound,endoscopic ultrasound(EUS),barium meal X-ray,computed tomography(CT)and magnetic resonance imaging(MRI)can be applied to evaluate the classifi⁃cation of GIST risk degree.However,different imaging methods have their own advantages and disadvantages,and how to accurately evaluate the classification of GIST risk degree by using imaging methods before surgery is still a subject that needs to be studied.In this paper,the application of imaging diagnosis in risk classification of gastrointestinal stromal tumors was reviewed in order to provide refer⁃ence for clinical diagnosis and treatment.
