Abstract:
Objective:To discuss the X-ray digital tomosynthesis (Digital Tomosynthesis, DTS) application value in the occult fractures of the scaphoid. Methods: we selected 19 patients in our hospital in 2012 examined by DTS, who were negative or highly suspicious of occult fracture with X-ray examination, and spiral CT (SCT) three-dimensional (3D) reconstructions were applied in seven patients. Results:There were 17 patients with fracture by DTS.7 patients showed fracture by spiral CT(SCT) three-dimensional(3D) reconstructions. Conclusion:Compared with X-ray examination, the image quality of Digital Tomosynthesis (DTS) is higher, which can show occult fracture better. Compared with CT, DTS can show spatial location of bony anatomy more clearly and can obtain more detailed information. With the important extension and supplement of CT and MRI, the distal tomosynthesisis is worth to be generalized for lower radiation, lower price, higher positive rate and high quality of the pictures.
