Analysis of diagnostic value of multi-row spiral CT in thoracoabdominal joint injury / 中国基层医药

ABSTRACT

Objective To evaluate the diagnostic value of multi－slice spiral CT in thoracic and abdominal joint injury. Methods From January 2015 to January 2018,200 patients with acute trauma were selected in the First Hospital of Yuncheng. Chest and abdomen X － ray examination and multi － row spiral CT examination were performed. The diagnostic sensitivity,specificity and accuracy of X－ray and spiral CT in the diagnosis of thoracoab-dominal joint injury were calculated and compared. The coincidence rate of X－ray and spiral CT in diagnosis of rib fracture and intrathoracic and abdominal organ injury was compared. Consistency test was used to analyze the consistency between X －ray, spiral CT diagnosis and clinical comprehensive diagnosis. Results The sensitivity, specificity and accuracy of X － ray in the diagnosis of chest joint damage were 89. 58% (129/144),85. 93% (47/56),88. 00% (176/200),respectively,which were lower than those of spiral CT[97. 22% (140/144),96. 43% (54/56),97.00% (194/200)](χ2=6. 818,4. 940,11. 676,all P ＜0. 05). The diagnostic coincidence rates of spiral CT for rib fracture,lung contusion,liver contusion,splenic rupture,pancreas injury and peritoneal injury were 97.67%(84/86),97. 06% (33/34),100. 00% (25/25),100. 00% (27/27),100. 00% (21/21),97. 96% (48/49),which were higher than those of X－ray(χ2=5. 733,3. 981,4. 348,5. 510,4. 421,5. 995,all P＜0. 05). After consistency test, there was good consistency between spiral CT and clinical comprehensive diagnostic results(Kappa=0. 747),and medium consistency between X － ray and clinical comprehensive diagnostic results (Kappa=0. 563). Conclusion Multi －row spiral CT can be used to accurately diagnose the combined injury of chest and abdomen,as well as to identify the fracture of rib and the injury of internal organs and organs in the chest and abdominal cavity.
