在前列腺癌的分期中必须作骨扫描。所用示踪剂为~(99m)Tc(锝)的化合物,目前常用的是~(99m)Tc-MDP(锝-二磷酸甲基)。可描出异常图象主要是指放射性同位素(RI)集积较多。作者例举了一例椎体、肋骨、髂骨中见有异常集积的图象。但在局部的骨质增生、关节炎、骨折、骨髓炎、骨质疏松症中亦可见之。另一例触诊为B或C期的前列腺癌,因超声断层诊断为B期而先作骨扫描。在骨扫描中,两侧腕骨骨干、股骨下端可见呈对称性的RI异常集积。这些部位X线摄片时各关节
Bone scans must be performed during the staging of prostate cancer. The tracer used is a compound of ~(99m)Tc(bismuth), which is currently used for ~(99m)Tc-MDP (methylphosphonium-diphosphate). Abnormal images can be described mainly refers to the accumulation of radioactive isotopes (RI). The author exemplifies an image of abnormal accumulation in the vertebral body, ribs, and sacrum. However, it is also seen in local bone hyperplasia, arthritis, fractures, osteomyelitis, and osteoporosis. Another palpated prostate cancer with stage B or C. Bone scan was performed because the ultrasound was diagnosed as stage B. In the bone scan, symmetrical RI anomalies accumulate on both the carpal shafts and the lower femur.
