DR双能量减影技术在急诊胸腹部外伤诊断中的应用价值
Effectiveness of Application of the DES-DR Technique in Diagnosis of Chest and Abdominal Emergency Trauma
摘要
Abstract
Objective To investigate the effectiveness of application of DES-DR (Dual-Energy Subtraction Digital Radiography) technique in diagnosis of chest and abdominal emergency trauma.Methods DES was performed in 75 patients with 159 rib fractures, 60 pneumothorax patients and 45 subphrenic free gas patients so as to compare and analyze the results with standard DR images.Results The standard DR images showed 135 cases of fractures, 50 cases of pneumothorax and 30 cases of subphrenic free gas with the detection rates 84.9%, 83.3 % and 66.7% respectively. The DES images revealed 150 cases of fractures, 60 cases of pneumothorax and 42 cases of subphrenic free gas with the detection rates 94.3%, 100% and 95.6% respectively. Obviously higher detection rates were achieved through DES than standard DR. Conclusion DES-DR could clearly show lesions including the rib fractures, slight pneumothorax, small pulmonary nodules and a small amount of abdominal free gas, which realized the high diagnosis rate of chest and abdomen emergency trauma and deserved wider clinical promotion.关键词
