ObjectiveTo investigate the value of multislice spiral computed tomography (MSCT) post-processing reconstruction technique applied to the diagnosis of incomplete rib fracture. MethodsThe clinical data of 60 patients with incomplete rib fracture were analyzed retrospectively, whose conventional MSCT images were thinned down to 1.25 mm, and the images of incomplete fractures were analyzed by using three post-processing reconstruction techniques, including multiplane reconstruction (MPR), volume rendering (VR) and curve planar reformation (CPR). The effect and practicability between each technique in the diagnosis of incomplete rib fracture were compared. ResultsAmong the 60 patients, there were 138 incomplete rib fractures, of which 129 were detected by MPR, 117 by VR and 134 by CPR. The diagnostic accuracy rates were 93.48%, 84.78% and 97.10%, respectively, and there were statistically significant differences in diagnostic accuracy rates among different reconstruction techniques (all P＜0.05). The accuracy rate of VR+CPR+MPR in the combined diagnosis of incomplete rib fracture was 99.28% (137/138). ConclusionMPR is more convenient and practical in diagnosing incomplete rib fractures, and CPR is more effective in displaying incomplete rib fractures. The combined application of multiple post-processing techniques can improve the diagnostic accuracy rate.
