摘要
目的探讨多层螺旋CT(MSCT)影像诊断中老年胃肠道间质瘤(GIST)的价值。方法选取2017年4月~2018年12月我院接受治疗的186例GIST患者,均经手术病理证实,分析术前MSCT增强扫描及常规CT扫描,观察其影像表现。并根据检查方式不同将其分为对照组(常规CT)和观察组(MSCT),比较两组诊断的准确率、特异性、敏感性、漏诊率、诊断费用与诊断时间指标,并对GIST不同疾病严重程度患者的病灶形态、大小、生长方式、部位情况作分析比较。结果观察组诊断准确率、特异性、敏感性、诊断费用指标高于对照组,差异有统计学意义(P<0.05);观察组漏诊率低于对照组,差异有统计学意义(P<0.05);观察组诊断时间短于对照组,差异有统计学意义(P<0.05);两组疾病严重程度不同患者的病灶形态、大小、生长方式、部位情况比较,差异有统计学意义(P<0.05)。结论MSCT影像检查方法可有效显示GIST患者病理状况,提高其检出率,值得临床推广使用。
Objective To investigate the value of multi-slice spiral CT (MSCT) imaging in the diagnosis of gastrointestinal stromal tumors (GIST) in the elderly. Methods A total of 186 patients with GIST who treated in our hospital from April 2017 to December 2018 were selected confirmed by surgical pathology. The preoperative MSCT enhanced scan and conventional CT scan were performed to observe the results, image performance. According to different examination methods, they were divided into control group (conventional CT) and observation group (MSCT), and the accuracy, specificity, sensitivity, missed diagnosis rate, diagnosis cost and diagnosis time index of the two groups were compared. Analyze and compare the lesion morphology, size, growth pattern and location of patients with different severity of GIST. Results At the end of the test, the accuracy, specificity, sensitivity and diagnostic cost of the observation group were higher than those of the control group, and the differences were statistically significant (P<0.05). The missed diagnosis rate of the observation group was lower than that of the control group, and the difference was statistically significant (P<0.05);the diagnosis time of the observation group was shorter than that of the control group, and the difference was statistically significant (P<0.05). The difference of the lesion morphology, size, growth mode and location of the patients with different disease severity was statistically significant (P<0.05). Conclusion MSCT imaging method can effectively display the pathological status of patients with GIST and improve its detection rate, which is worthy of popularization.
