- A retrospective analysis was conducted on 28 patients with a clinical history of unilateral trauma and a confirmed unilateral rib fracture diagnosed by spectral CT between May 2024 and September 2024. Inclusion criteria for the study group were: (1) trauma within 48 hours; (2) unilateral chest wall trauma with a CT diagnosis of unilateral rib fracture; (3) no significant separation or displacement of the fracture ends. Exclusion criteria were: (1) a history of cancer; (2) motion artifacts in the rib images; (3) a history of rib fracture or old fractures detected by rib CT; (4) a marrow cavity at the fracture site smaller than 4mm. Two radiologists with more than five years of experience in chest imaging jointly analyzed the CT images, recorded the electron density values within the marrow cavity at the fracture site and the corresponding contralateral healthy segment, calculated the difference in electron density values between the fracture site and the contralateral healthy segment, and analyzed the differences in electron density values at the fracture site and the corresponding contralateral healthy segment.
- A retrospective analysis was conducted on 6 patients confirmed to have no rib fractures upon re-examination between May 2024 and September 2024. Inclusion criteria for the control group were: (1) negative rib CT results within 48 hours after trauma; (2) negative rib CT re-examination results within 3-4 weeks after trauma. Exclusion criteria were the same as those for the study group. The differences in electron density values between corresponding anatomical segments of the left and right ribs were analyzed in the control group.
- The differences in electron density values between the affected and contralateral healthy ribs in the fracture group were compared with the differences between the left and right ribs in the healthy group. The ROC curve was used to analyze the diagnostic value of the difference in electron density values between the affected and contralateral sides in the study group for rib fractures.
