薄层MSCT扫描对食管异物检出情况及图像显示质量研究

Detection and the Quality of Image Display of Thin-Layer MSCT for Esophageal Foreign Bodies

目的分析薄层MSCT扫描对食管异物检出情况及图像显示质量。方法选取本院2016年3月至2019年9月收治且经内镜或手术确诊的71例食管异物患者作为研究对象。分析异物形状、大小与周围组织关系等影像学特征;比较MSCT检查与X线对食管异物的检出率。结果71例食管异物患者经薄层MSCT诊断,检出率为100.00%;经X线平片诊断,检出率为83.10%,明显低于薄层MSCT检查(P<0.05);CT可见高密度影,呈条状、小片样及斑片样,34例异物形态不规则或呈分叉状。71例患者中2例异物刺入主动脉,4例并发纵隔脓肿积气。结论薄层MSCT对食管异物的检出率高于X线平片,且图像显示质量好,临床在经X线等常规检查无法明确诊断或显像欠清楚的情况下进行CT扫描,可有效减少漏诊、误诊率,提高诊断准确率。

Objective To analyze the detection and the quality of image display of thin-layer MSCT for esophageal foreign bodies.Methods 71 patients with foreign body in the esophagus who were admitted to our hospital from March 2016 to September 2019 and diagnosed by endoscopy or surgery were selected.The imaging features such as the shape and size of the foreign body and the relationship with the surrounding tissues were analyzed.The detection rates of esophageal foreign bodies between MSCT and X-ray were compared.Results Among 71 patients with foreign body in the esophagus,the detection rate of thin-layer MSCT was 100.00%.The detection rate of X-ray was 83.10%,which was significantly lower than that of thin-layer MSCT(P<0.05).CT showed high-density shadows,which were strip-shaped,patch-like,and patch-like.The foreign bodies in 34 cases were irregular or bifurcated.In the 71 patients,and 4 patients had mediastinal abscess pneumatosis.Conclusion The detection rate of thin-layer MSCT for esophageal foreign bodies is higher than that of X-ray,and the quality of image display is good.In clinic,CT scan is performed when routine examinations such as X-rays cannot be clearly diagnosed or imaging is not clear,which can effectively reduce the rate of missed diagnosis and misdiagnosis and improve the accuracy of diagnosis.
