目的探讨数字化断层融合技术在隐蔽骨折诊断中的优势.方法搜集X线平片可疑骨折但不确定或平片阴性但临床体征明显、不能排除隐蔽骨折的135例外伤患者,行数字化断层融合检查,对比观察X线平片及数字化断层融合图像,分析行数字化断层融合技术对隐蔽骨折显示的优势.随访135例患者的临床资料,并与影像诊断结果对照.结果 61例X线平片检查阴性,数字化断层融合图像显示寰枢椎骨折3例,半脱位4例;四肢关节骨折20例;手足及腕部骨折11例;颈椎、胸椎、腰椎骨折7例;骶尾骨骨折8例;鼻骨骨折4例;胸骨骨折、肋骨骨折、眼眶骨折、下颌骨骨折各1例;X线平片可疑骨折或脱位51例,数字化断层融合图像肯定骨折诊断34例,排除骨折17例;X线平片和数字化断层融合均诊断正常23例.随访观察断层融合技术诊断与临床诊断相符,诊断骨折共95例.结论数字化断层融合技术在诊断一些深在部位和复杂部位的骨折方面具有独特的优越性,提高了骨折的检出率和诊断正确率.

Objective To evaluate the digital tomosynthesis in the diagnosis of occult bone fracture. Methods Both DR and DTS were performed in 135 cases with traumatic-induced pain. All the cases were suspected of bone fractures but with no abnormal findings in DR images. Two radiologists reviewed all the images and diagnosed in consensus. All cases were followed up and the imaging diagnoses were reviewed. Results Bone fractures or joint dislocations of 61 cases were shown in DTS images but not in DR images, including atlanto-axial fracture and subluxation in 7 cases, articular fracture of limbs in 20 cases, bone fractures of wrist, hand and foot in 11 cases, fractures of cervical, thoracic and lumbar vertebra in 7 cases, fracture of sacrococcyx in 8 cases, fracture of nasal bone in 4 cases, fractures of Sternum ,rib ,orbit and mandible in 1 case. Thirty-four cases with bone fractures were determined by using DTS in suspected cases and 17 cases were denied. Both DR and DTS images showed normal findings in 23 cases. Imaging diagnoses of all cases were consistent with the results of follow up. Conclusion DTS can depict bone fractures especially in the deep and complex bony structures, which may improve the diagnostic accuracy of bone fracture.
