Abstract

BackgroundTo explore the clinical significance of digital tomographic fusion imaging in the diagnosis of avascular disease of the femoral head in adults.MethodsEighty-two adult patients with avascular necrosis of the femoral head confirmed by MRI in the department of orthopedics of our hospital were studied retrospectively. The related signs of adult avascular necrosis of the femoral head were diagnosed by digital tomographic fusion imaging, and the detection rates of digital X-ray (DR) and digital tomosynthesis (DTS) were compared to clarify the clinical value of digital tomographic fusion imaging in the diagnosis of adult avascular necrosis of the femoral head.ResultsDTS detected DR and 78 cases identified 55 cases. Taking the results of CT/MRI as the gold standard, the sensitivity, specificity, positive predictive value, and negative predictive value of DR and DTS in the diagnosis of ANFH were calculated. There was a significant difference in the detection rate between the two methods (P < 0.05).ConclusionThe digital tomographic fusion imaging technique has the advantages of high detection rate and excellent image quality, is economical, and is worth popularizing. For those with negative X-rays, DTS diagnosis and CT or/and MRI can avoid unnecessary CT and MRI examinations, which is helpful to reduce the waste of medical resources.

Highlights

To explore the clinical significance of digital tomographic fusion imaging in the diagnosis of avascular disease of the femoral head in adults
We examine the related signs of adult Avascular necrosis of the femoral head (ANFH) diagnosed by digital tomosynthesis (DTS) and the detection rates of digital X-ray (DR) and DTS to clarify the clinical value of digital tomographic fusion imaging in the diagnosis of adult avascular necrosis of the femoral head
DR can display the full picture of the hip joint and the femoral head, observe the changes of the joint space, and determine whether there is bone destruction, but because the DR images of some patients are not typical, it is easy to cause missed diagnosis and misdiagnosis
