Abstract
Purpose : To evaluate the loss of bone mineral contents(BMC) in lumbar spine within the radiation field for cervical cancer treatment, BMC in the irradiated patient group was compared with that of a normal control group. Method and materials : Measurements of BMC in the trabecular bone in lumbar spines(L3-L5) were performed in the both patient and normal control groups. Investigators used dual-energy quantitative computerized tomography(DEQCT) using Photon energy of 120 and 80kVp, The numbers of Patient and control groups were 43 in each with age distribution of fifth to seventh decade of women. The numbers of control group were 22 in fifth, 10 in sixth and 11 in seventh decade, those of patient group were 14 in filth, 14 in sixth, and 15 in seventh decade of women. The radiation field was extended to L5 spine for Pelvic irrdiation with 45-54Gy of external radiation dose and 30Gy of high dose rate brachytherapy in cervical cancer, Results : The BMC is decreased as increasing age in both control and patient groups. BMC in lumbar spine of patient group was decreased by about
목적 : 자궁경부암 환자에서 방사선치료시 방사선조사면내의 골무기물 함량변화를 정상대조군 촉 환자군의 골무기물 함량을 비교하여 방사선이 골무기물에 미치는 영향을 조사하였다. 재료 및 방법 : 120kVp와 80kVp X선을 이용하는 이중에너지 전산화단층 촬영을 이용하여 환자군과 정상대조군에서 제 3, 4 및 제 5 요추의 해면골무기물 함량을 정량적으로 측정하였다. 총인원수는 정상대조군 43명과 환자군 43명으로서 86명이며 각 연령별로는 정상대조군 40대 22명, 50대 10명, 60대 11명이었고, 환자군에서는 40대 14명, 50대 14명, 60대 15명이었다. 방사선조사 부위는 골반과 제 5 요추를 포함하여 치료하였으며 외부방사선량은 45-54Gy였으며, 강내치료는 고선량률로 300y를 조사하였다 결과 : 정상대조군과 환자군의 여성에서 골무기물 함량은 나이가 증가함에 따라 감소함을 보였으며, 환자군은 정상군에 비해 약
