目的分析胃淋巴瘤(GL)的CT征象特点,并评价64排旋螺CT的诊断价值。方法随机选取我院于2014年4月至2016年4月收治的30例GL患者为研究对象,治疗前均经64排旋螺CT扫描诊断,将扫描结果与最终的病理诊断结果相对比,观察其诊断符合率,总结CT征象特点。结果 64排螺旋CT诊断与病理诊断的符合率为93.33%;CT征象显示GL有单一型受累和多样型受累之分;胃壁呈弥漫性不均匀增厚,其中胃壁最大厚度在10.0 mm以上的患者比例大于20.0 mm以上患者(P<0.05);病灶CT强化程度与周围肌肉强化程度无显著差异(P>0.05);肝胰直接受累比例明显大于左肾周围脂肪囊直接受累(P<0.05)。结论 GL的CT征象特点突出,而且采用64排旋螺CT可提高GL的确诊率,对临床治疗具有重要意义。
Objective To analyze the CT features of gastric lymphoma (GL) and evaluate the diagnostic value of 64-row spiral CT. Methods Thirty patients with GL who were treated in our hospital from April 2014 to April 2016 were randomly selected. All cases were examined by 64 spiral CT scan before treatment, and the results were compared with the final pathological diagnosis. The diagnosis coincidence rate, summarize the characteristics of CT signs. Results The coincidence rate of 64-slice spiral CT diagnosis and pathological diagnosis was 93.33%. The CT findings showed that GL had a single type of involvement and multiple types of involvement. The gastric wall showed diffuse uneven thickening. The patients with maximum gastric wall thickness above 10.0 mm (P <0.05). There was no significant difference in the degree of CT enhancement between the lesion and the surrounding muscle (P> 0.05). The proportion of direct involvement of hepatopancreas was significantly higher than that of the direct fat capsule around the left kidney (P <0.05). Conclusion The CT features of GL are prominent, and using 64-row spiral CT can improve the diagnosis rate of GL, which is of great significance for clinical treatment.
