Abstract 【Objective】To compare the diagnostic value of the first dual energy subtraction (DES) and low-dose multi-slice spiral CT (MSCT) in the diagnosis of concealed/occult rib fractures in a short period of time. 【Methods】The imaging data of 118 highly suspected rib fracture patients admitted to our hospital from October 2017 to October 2018 were retrospectively analyzed. All patients underwent DES and low-dose MSCT within 3 days after trauma. The results were compared with gold standard image data which were collected with routine dose of MSCT after 4 ~ 8 weeks. 【Results】Of the 118 patients diagnosed with conventional MSCT, 147 had rib fractures, of which 88 were diagnosed as occult rib fractures. The sensitivity, specificity and coincidence rate of low dose MSCT in the diagnosis of occult rib fracture were 97. 40% (75/77), 81. 43% (57/70) and 89. 80% (132/147), respectively. The sensitivity of DES in the diagnosis of occult rib fracture was 96.25% (77/80), the specificity was 83.58% (56/67), and the coincidence rate was 90.48% (133/147).There was no significant difference in sensitivity, specificity and coincidence rate between the two methods (P > 0.05). 【Conclusion】 DES and low-dose MSCT have comparable diagnostic value in the diagnosis of occult rib fracture. We can choose different examination methods according to the patient's specific situation and the indication of the disease.
