Problems solved by technology
The main techniques for early clinical diagnosis of avascular necrosis of the femoral head are X-ray, X-ray computed tomography (Computed Tomography, CT) and magnetic resonance imaging (Magnetic Resonance Imaging, MRI). , in addition to the advantages of MRI in early diagnosis, the specificity and sensitivity of these imaging diagnostic methods are low
With the advancement and development of medical technology, a new diagnostic technology has emerged in clinic, that is, single-photon emission computed tomography (Single-Photon Emission Computed Tomography, SPECT) / X-ray computed tomography (Computed Tomography, CT) quantitative research, However, after reviewing the literature, there are few studies on SPECT / CT quantitative methods for bone metabolism in avascular necrosis of the femoral head.

The invention discloses a quantitative detection method for avascular necrosis of the femoral head. The quantitative index is the radioactive distribution per gram of tissues. The method includes theimplementation steps of an image acquisition step, a data acquisition step, a bone density calculation step and a step of calculating the radioactivity distribution per gram of tissues. According to the quantitative detection method, the quantitative index of SPECT / CT avascular necrosis of the femoral head can be obtained, and the difficulty in quantitative analysis of the avascular necrosis of the femoral head can be solved by utilizing SPECT / CT imaging. The method can be used for assessment of the avascular necrosis of the femoral head and has high specificity.
Description
technical field [0001] The invention relates to the field of orthopedic imaging identification, in particular to a quantitative detection method for avascular necrosis of the femoral head. Background technique [0002] Avascular necrosis of the femoral head is one of the more common clinical diseases. The femoral head necrosis is mainly a process of pathological evolution. The main clinical symptoms are changes in the structure of the femoral head, and joint inflammation leads to femoral head dysfunction. Most patients with femoral head necrosis have severe pain, which makes walking dysfunction. The main techniques for early clinical diagnosis of avascular necrosis of the femoral head are X-ray, X-ray computed tomography (Computed Tomography, CT) and magnetic resonance imaging (Magnetic Resonance Imaging, MRI). , in addition to the advantages of MRI in early diagnosis, the specificity and sensitivity of these imaging diagnostic methods are low. With the advancement and dev...
