Clinical application of SPECT bone imaging in diagnosing bone metastasis from prostate cancer

Objective:To probe the clinical value of the combined detection of radionuclide bone imaging and plasma levels of prostate specific antigen(PSA) in patients with prostate cancer.Methods: Whole body bone imaging was performed for 163 patients with prostate cancer,and the incidence rate of bone metastasis predilection site,focus distribution and The relation between PSA and bone metastasis was analyzed.Results: Among 163 cases,125 cases with bone metastases were found by radionuclide bone imaging,with the positive rate 76.7 %.In the 125 cases,the vertebral body has the most incident of osseous metastasis(76.8 %),then the pelvis(71.2 %),thoracic part(53.6%),limbs bone(13.6%),skull and the other parts(8.8%).Conclusion: The incidence rate of osseous metastasis is very high for the prostate cancer patients,and the incidence of the osseous metastasis has definite rules and features.It is worth diagnosing the prostate cancer with the whole body nuclide bone imaging and plasma levels of prostate specific antigen(PSA),it should be a routine examination for the prostate cancer.
