Abstract
Objective To explore the value of high frequency ultrasound and MSCT in the diagnosis of occult fracture of rib. Methods 50 cases of occult rib fracture were in accordance with the principle of voluntary were divided into two groups, 32 cases of group A and group B, 18 cases of line of high frequency ultrasound and MSCT examination respectively, analysis of the image data. Results ①A set of ultrasonic diagnosis of rib fracture 30 cases (52), 2 cases of misdiagnosis, diagnosis accuracy rate 93.75%.Single fractured ribs on 20 cases, 11 cases multiple fractured ribs, costal cartilage fracture in 1 case, rib fracture with 3~10 before and axil ary edge, fracture dislocation, 0.5 to 6.5 mm.②The B group of MSCT in the diagnosis of rib fracture of 17 cases (35), 1 case of missed diagnosis, diagnostic accuracy of 94.44%.Single rib fractures in 12 cases, 6 cases of multiple fractured ribs, completeness fractured ribs 21 root, incomplete 14 root ribs fracture, 21 root complete interruption of fractured ribs end displacement are not more than three cortical thickness. ③both the accuracy rate of diagnosis is consistent, the fracture location, number and displacement can clearly display.Conclusion High frequency ultrasound and MSCT in the diagnosis of occult rib fracture were higher accuracy.Considering both the advantages and disadvantages, ultrasound can be as the main examination methods of diagnosing occult rib fracture.关键词
