骨组织是乳腺癌远隔转移的最常见部位，骨转移也是导致患者死亡的首要原因。在众多检查中，影像学检查对于乳腺癌骨转移的意义最为重大。临床研究的深入开展使得X线、骨扫描、磁共振等传统检查技术诊断效能不断提高，而正电子发射计算机断层显像（position emission computed tomography，PET）及PET/CT的广泛使用、分子核医学研究的不断深入及影像成像标志物的应用使得众多的进展期乳腺癌患者明显获益。PET以及PET/CT检出率高特异性好，同时可观察肿瘤的全身组织播散情况，是肿瘤影像诊断的最高手段。本文作者旨在就PET和PET/CT对乳腺癌骨转移早期诊断的价值进行文献复习探讨，为今后的临床诊断提供一定的参考依据。
