Abstract
Objective To study the diagnostic value of multi slice spiral CT volume scan with different reconstruction al-gorithms in the diagnosis of occult fracture of rib. Methods 194 cases of occult rib fractures in patients with first chest CT images were analyzed retrospectively,all cases were used 8 kinds of reconstruction algorithms ( soft tissue, standards, chest, lung, fine, bone,bone,edge) ,and the postprocessing image were by multiplanar reconstruction( multi-planar reconstruction,MPR) and curved planar reformation( curved planer reconstruction,CPR) . Results In the 194 cases of chest trauma,521 of occult fracture,8 kinds of reconstruction algorithms were detected occult fracture as the ( 362、378、401、419、467、507、495、472 ) . The detection of bone and bone +reconstruction algorithms were the highest,respectively 97. 3%,95. 0%,and the difference between the two reconstruc-tion algorithms was no statistical significance ( P>0. 05 ) . Conclusion It was beneficial to improve the detection rate of occult fracture of rib by selecting bone or bone + reconstruction algorithm in clinical work.关键词
