Abstract:
Objective To compare the characteristics of the distribution of bone metastases in lung cancer, breast cancer and esophageal cancer.
Methods SPECT bone imaging of the entire body was performed after the injection of99Tcm-methylene diphosphonate(99Tcm-MDP)in 454 cases.Analyzed the distribution of metastatic bone lesions in upper limbs'middle and distal or the pelvis and lower limbs and the distinction of metastatic bone lesions between different diseases were distinguished.
Results Of all the 454 patients, 120 cases showed abnormal radionuclide concentration in the region of upper limbs'middle and distal or the pelvis and lower limbs.One thousand three hundreds and three metastatic bone lesions were found in all the patients893 were in lung cancer(64.4%), 361 were in breast cancer(27.7%)and 103 were in esophageal cancer(7.9%).Radioactive uptake in rotor area of femur lesions in these diseases was demonstrated to be of large proportion.
Conclusions The result of99Tcm-MDP bone imaging shows that the distribution of the metastatic bone lesions in lung cancer, breast cancer and esophageal cancer vary from place to place.
