放射治疗引起的光减少异常在骨扫描上识别是重要的，因为它们经常影响纵向或横向对称性。在通过67个端口（包括中轴骨骼）治疗的43名患者中研究了这种现象。骨剂量范围为450- 6，700 R（平均值+/- S.D.）= 3，600 +/-1，700 R），治疗中点至扫描时间间隔为1-19个月。治疗后4 ~ 6个月出现光减少缺陷。在治疗后超过4个月研究的20例患者（31个端口）中，14例（45%）存在此类缺陷。在接收不到2，000 R的地区没有检测到。作者得出结论，了解患者的放疗史是解释后续骨扫描的重要前提。
Photopenic abnormalities induced by radiation therapy are important to recognize on bone scans, since they often affect longitudinal or lateral symmetry. This phenomenon was studied in 43 patients treated through 67 ports (including the axial skeleton). Bone doses spanned 450-6,700 R (mean +/- S.D. = 3,600 +/- 1,700 R), and the interval from the midpoint of therapy to the time of the scan was 1-19 months. Photopenic defects appeared between 4 and 6 months after therapy. Of 20 patients (31 ports) studied more than 4 months after therapy, 14 (45%) had such defects. None was detected in regions receiving less than 2,000 R. The authors conclude that knowledge of a patient's radiotherapy history is an important prerequisite to interpretation of subsequent bone scans.
