ObjectiveTo explore the application value of SPECT/CT on fracture healing.

MethodsA retrospective analysis was done among 76 patients with fracture as evidenced by image data from January 2008 to August 2017. Fifty-eight cases with fracture revealed by a SPECT/CT fusion image with surgical treatment, 18 cases with nonsurgical treatment, and 76 cases of bone fracture clinical healing that failed to meet standards were retrospectively analyzed after more than 6 months of treatment. A SPECT/CT image fusion imaging device was applied to 76 cases of fracture detected with SPECT, CT scan, and SPECT/CT fusion imaging. The characteristics of the fractures in terms of radioactive distribution and CT were examined, and the radioactive strength of the fracture was observed to determine whether radioactivity passed continuously through the fracture line or crossed both sides of the fracture. The healing ability of the fracture was evaluated, and fracture healing cases were confirmed through surgery or clinical follow-up.

ResultsA total of 76 fractures were collected and examined through SPECT/CT, and 58 cases of uptake that passed through the fracture line and crossed on both sides of the fracture end were obtained. This finding indicated that the fracture was in the process of healing and that fracture could heal. Furthermore, 52 cases were confirmed after conservative treatment was administered, and 6 cases of fracture were nonunion. For 18 cases, no nuclide concentration was detected in the fracture end, and the fracture was nonunion. The final diagnosis was confirmed through surgery, and the diagnostic accuracy rates were 89.66%(52/58) for fracture healing and 100%(18/18) for nonunion.

ConclusionSPECT/CT imaging could accurately evaluate fracture healing and had an important application value.
