胃间质瘤(GST)是一种起源于间叶组织、具有分化潜能的胃肠道肿瘤,起病隐匿,多数因出现症状而就诊,临床表现差异较大,且部分恶性程度较高,严重影响患者的生命健康。早期诊断、正确评估肿瘤的良恶性对选择合适的治疗方案具有重要意义,可明显改善患者预后。影像学检查在术前对病灶进行定位、危险程度评估、术后评价治疗疗效上具有重要意义。本文综述了GST在影像学上的表现及最近几年影像学诊断新技术,为临床诊疗提供指导。
Gastrointestinal stromal tumor (GST) is a gastrointestinal tumor with differentiation potential originated from mesenchymal tissue. Occult onset is occult. The majority of patients have symptoms because of their different clinical manifestations. Some of them are highly malignant Affect the patient’s life and health. Early diagnosis, a correct assessment of the benign and malignant tumors of the right choice of treatment programs of great significance, can significantly improve the prognosis of patients. Imaging examination in the preoperative localization of the lesion, the assessment of the degree of risk, postoperative evaluation of the efficacy of the treatment of great significance. This review summarizes the imaging findings of GST and new imaging diagnostic techniques in recent years, providing guidance for clinical diagnosis and treatment.
