[摘要]目的 探討128层螺旋CT检查及多平面重组(MPR)后处理技术在胃肠间质瘤(GIST)术前诊断中的应用价值,为今后的临床诊断工作提供有价值的参考依据。方法 选取2017年1月~2019年6月我院收治的20例经手术病理及免疫组织化学证实的GIST患者作为研究对象,对其进行128层螺旋CT检查,并应用MPR后处理技术,以病理及免疫组化结果为依据,统计病灶检出情况、CT检查及MPR后处理技术的定位、定性结果。结果 患者经CT检查及MPR后处理技术,检出GIST病灶位于胃部者13例,位于小肠者5例,位于十二指肠者2例;黏膜状态表现为光滑者13例,黏膜存在明显溃疡者7例;囊实性15例,实性5例;增强扫描可观察到肿瘤均匀强化者12例,不均匀强化者8例;均匀强化患者中,病灶确诊为良性者11例,潜在恶性1例;不均匀强化患者中,病灶确诊为良性者2例,恶性者6例。CT检查及MPR后处理技术的定位及定性结果与病理检查比较,差异无统计学意义(P>0.05)。结论 128层螺旋CT检查及MPR后处理技术可获得准确的定位与定性结果,具有较高的临床诊断准确率,值得关注并推广。

[Abstract] Objective To analyze the application value of 128-slice spiral CT and multi-planar (MPR) post-processing technology in preoperative diagnosis of gastrointestinal stromal tumor (GIST), so as to valuable reference for clinical diagnosis in the future. Methods From January 2017 to June 2019, 20 GIST patients confirmed by surgical pathology and immunohistochemistry were selected as the research objects. A total of 128 slice spiral CT was performed on them, and MPR post-processing technology was applied. Based on the results of pathology and immunohistochemistry, the detection of lesions, the location and qualitative results of CT and MPR post-processing technology were statistically analyzed. Results By CT and MPR post-processing technology, 13 cases of gist were located in stomach, 5 in small intestine and 2 in duodenum. There were 13 cases of mucosal appearance and 7 cases of obvious ulcer in mucosa. There were 15 cases of solid capsule and 5 cases of solidity. Enhanced scanning revealed 12 cases of uniform tumor enhancement and 8 cases of uneven enhancement. Among the patients with uniform enhancement, 11 cases were diagnosed as benign and 1 case was potentially malignant. Among the patients with uneven enhancement, the lesions were diagnosed as benign in 2 cases and malignant in 6 cases. There were no significant differences between the location and qualitative results of CT and MPR post-processing technology and pathological examination (P>0.05). Conclusion 128-slice spiral CT and MPR post-processing technology can obtain accurate localization and qualitative results, and have high clinical diagnostic accuracy, which is worthy of attention and promotion.

CT检查为目前GIST的主要检查手段,其不仅可以对病灶形态、内部结构进行显示,并且能够观察包块与周边组织器官的毗邻关系,依据影像特征对病变性质进行判断,对术前治疗方案选择、术后监测等均具有重要作用[10-11]。经实践证实,在影像学诊断过程中,多层螺旋CT具有扫描时间短、定位准确、扫描速度快等优势,能够对肿瘤血供呛咳、肿瘤供血血管进行动态观察,可为临床诊断提供重要的参考信息[12-13]。

本研究选取我院收治的20例GIST患者作为研究对象进行回顾性分析,结果显示,CT检查及MPR后处理技术的定位及定性结果与病理检查结果比较,差异无统计学意义(P>0.05)。提示采用128层螺旋CT检查及MRP后处理技术可取得高质量的图像,方便诊断医师对GIST发生具体部位、肿瘤的大小、形态边界、密度、生长方式、胃肠道管腔、淋巴结或远处转移等情况进行精确分析,有利于提高诊断定位及定性准确率,方便临床进行手术治疗及预后处理,降低了手术风险及医疗事故发生率。MPR后处理技术,是一个非常方便实用的技术。利用该技术对全身脏器的各种病变进行冠状位、矢状位、水平位和斜位的重建,该技术在GIST的应用,使得医师能够获得更全面、更立体的图像信息[14-15]。

综上所述,128层螺旋CT检查及MRP后处理技术可以取得高质量的图像,并且术后可随访复查,方便诊断医师对病变进行精确诊断,提高了诊查效率,并可有效地指导临床治疗,对于优化提升医院的诊疗水平以及改善患者预后均具有积极意义。
