液体流注效应在CT诊断感染性病变中的临床研究

Clinical study on value of liquid flow injection effect in CT diagnosis of infectious disease

目的：探讨液体流注效应在CT诊断腹膜腔及体腔壁感染性病变的作用，分析液体流注效应对CT诊断感染性疾病的临床价值，提高临床诊断准确率。方法选取2010年2月－2014年1月腹膜腔及体腔壁感染性病变患者31例为研究对象，对所有患者均进行CT检查，对患者先行常规腹腔至上而下扫描，层厚和层间距均为10mm，局部细节层厚为5mm，速率为1．5～2．0ml／s，然后在造影剂注入后的45s在进行扫描调整准直器宽度在5～10mm，观察使用检查结果。结果所有患者在造影剂注入后检查结果显示，在腹膜腔、盆腔、体腔壁感染的CT影像学上表现均较明确，主要体现为梭状的线形影。结论运用液体流注效应能提高CT诊断腹膜腔及体腔壁感染性病变的诊断准确率。

OBJECTIVE To explore the role of liquid flow injection effect in CT diagnosis of peritoneal and body cav‐ity wall infections and analyze the clinical value of the liquid flow injection effect in the CT diagnosis of infection diseases so as to improve the accuracy of clinical diagnosis .METHODS A total of 31 patients with peritoneal and body cavity wall infections who were treated in the hospital from Feb 2010 to Jan 2014 were recruited as the study objects ,all the patients underwent the CT examination ,the patients were firstly given routine top‐down abdominal scan ,with both the layer thickness and spacing of 10 mm ,the thickness of the local detail of 5 mm ,the velocity of 1 .5‐2 .0 ml/s ,finally the patients were scanned with the width of collimator adjusted as 5‐10 mm at 45s of being injected with contrast agents ,and the examination results were observed .RESULTS After the contrast agents were injected ,the examination results showed that the CT imaging was characterized by the peritoneal ,pelvic ,and body cavity wall infections ,with the line of condition dominant .CONCLUSION The application of the liquid flow injection effect may improve the accuracy of CT diagnosis of the peritoneal and body cavity wall infectious disease .
