摘要 【目的】比较X射线断层融合成像、全数字化X射线摄影对桡骨头骨折分型诊断价值及辐射剂量。【方法】回顾性分析2020年2月至2022年2月两院收治的201例桡骨头骨折患者的临床资料,以临床最终诊断为金标准,其中Mason分型Ⅰ型83例、Ⅱ型77例、Ⅲ型41例。所有患者均接受X射线断层融合成像、全数字化X射线摄影检查,比较两种影像学检查对桡骨头骨折的检出率、对桡骨头骨折分型的诊断价值、显示骨质结构与周围软组织图像质量及检查的辐射剂量。【结果】X射线断层融合成像对桡骨头骨折的检出率高于全数字化X射线摄影,差异有统计学意义(P<0.05)。X射线断层融合成像诊断桡骨头骨折的总灵敏度高于数字化X射线摄影,差异有统计学意义(P<0.05)。X射线断层融合成像对Mason分型Ⅱ型、Ⅲ型骨折的灵敏度高于全数字化X射线摄影,差异有统计学意义(P<0.05)。X射线断层融合成像显示骨质结构的优秀率高于全数字化X射线摄影,差异有统计学意义(P<0.05)。X射线断层融合成像显示周围软组织的优良率高于全数字化X射线摄影,差异有统计学意义(P<0.05)。X射线断层融合成像辐射剂量低于全数字化X射线摄影,差异有统计学意义(P<0.05)。【结论】相比于全数字化X射线摄影,X射线断层融合成像对桡骨头骨折分型的诊断价值更高,其可提高图像质量,且可降低辐射剂量。

Abstract：【Objective】 To compare the diagnostic value and radiation dose of tomosynthesis and full digital radiography for the classification of radial head fractures. 【Methods】 The clinical data of 201 patients with radial head fractures treated in the two hospitals from February 2020 to February 2022 were retrospectively analyzed, with the final clinical diagnosis as the gold standard. Among them, there were 83 cases of Mason type Ⅰ fractures, 77 cases of Mason type Ⅱ fractures and 41 cases of Mason type Ⅲ fractures. All patients underwent tomosynthesis and full digital radiography. The two imaging modalities were compared in terms of fracture detection rate, diagnostic performance for radial head fracture classification, image quality of bone structure and surrounding soft tissues, as well as radiation exposure. 【Results】 Tomosynthesis achieved a significantly higher fracture detection rate than full digital radiography (P<0.05). The overall diagnostic sensitivity of tomosynthesis for radial head fractures was statistically superior to full digital radiography (P<0.05). For Mason type Ⅱ and Ⅲ fractures, tomosynthesis showed significantly higher diagnostic sensitivity (P<0.05). Tomosynthesis yielded a significantly higher excellent visualization rate of bone structures and a better excellent/good rate of surrounding soft tissues (P<0.05). In addition, tomosynthesis delivered significantly lower radiation dose than full digital radiography (P<0.05). 【Conclusions】 Compared with full digital radiography, tomosynthesis has higher diagnostic value for radial head fracture classification, and it can optimize image quality while reducing radiation exposure.
