Purpose Rib fractures are the most common form of fracture in blunt chest trauma, with an incidence rate of approximately 50% [1]. Traditional chest X-ray radiography has a sensitivity of only 15% for detecting rib fractures [2]. Although CT scans are currently the primary diagnostic tool in clinical practice and can detect more rib fractures than chest X-rays, some rib fractures may still be missed during the initial CT examination [3]. Even when artificial intelligence technology is used as an auxiliary...
Read more Methods and materials 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...
Read more Results The average electron density value within the marrow cavity at the fracture site in the unilateral rib fracture group was 106.1% EDW, higher than the corresponding contralateral healthy segment at 102.1% EDW (P<0.001). There was no statistically significant difference in electron density values between corresponding anatomical segments of the left and right ribs in the normal control group (P>0.05). The average difference in electron density values between the affected and contralateral sides in the fracture group was 4.07% EDW, higher...
Read more Conclusion Electron density mapping in spectral CT has certain diagnostic value for detecting rib fractures.Limitations: (1) This study was conducted over a short period and did not collect enough follow-up cases of rib fractures to identify occult fractures based on bone callus formation as the gold standard. Therefore, further collection of cases undergoing rib CT follow-up is needed, with bone callus formation as the gold standard, to evaluate the value of electron density technology in detecting occult fractures; (2) The sample...
