目的探讨螺旋CT对胃间质瘤的诊断价值及其表现。方法回顾性分析我院2010年1月至2012年1月期间收治的32例胃间质瘤患者,所有患者均进行了螺旋CT平扫和增强扫描。结果这32例患者经过螺旋CT平扫后发现,患者的胃腔内、胃腔外或胃腔内外同时发现有软组织肿块存在,肿块呈密度均匀或不均匀分布密度影。经过增强处理后,肿块呈中心坏死、囊变、周边强化或肿块强化明显。其中,良性肿瘤11例,肿块最大的直径约<5cm,肿瘤边界清楚,多呈均匀强化状态;而恶性肿瘤21例,肿块直径平均>5cm,肿瘤边界不清楚,有15例肿块内出现坏死灶,7例出现病灶转移现象。结论通过应用螺旋CT平扫和增强扫描技术后,临床诊断胃间质瘤的检出率和准确率明显提高,同时,螺旋CT增强平扫对胃间质瘤的定位诊断和定性诊断具有显著的诊断学意义。
Objective To investigate the diagnostic value and performance of spiral CT in gastric stromal tumors. Methods A retrospective analysis of 32 patients with gastric stromal tumors admitted to our hospital from January 2010 to January 2012, all patients underwent spiral CT plain scan and enhanced scan. Results The 32 patients after spiral CT plain scan found that patients with gastric cavity, gastric cavity or gastric cavity both inside and outside the presence of soft tissue mass, mass density or uneven distribution of density. After enhanced treatment, the tumor showed central necrosis, cystic degeneration, peripheral enhancement or mass enhancement significantly. Among them, benign tumors in 11 cases, the largest diameter of the tumor about <5cm, the tumor clear boundary, mostly uniformly enhanced state; and malignant tumors in 21 cases, the average tumor diameter> 5cm, tumor boundaries are not clear, there were 15 cases of necrosis within the tumor , 7 cases of focal metastasis. Conclusions The detection rate and accuracy of clinical diagnosis of gastric stromal tumors were significantly improved by using spiral CT scan and enhanced scan technique. At the same time, the enhanced scan by spiral CT enhanced the localization and diagnosis of gastric stromal tumors Diagnostic Significance.
