前列腺癌骨转移影像诊断方法研究进展

Progress of imaging in the diagnosis of bone metastases of prostate cancer

前列腺癌具有很高的骨转移倾向，在初次诊断时即有较高的骨转移率，所以前列腺癌患者早期筛查骨转移对前列腺癌的分期、治疗及预后判断具有重要意义。放射性核素骨显像是临床常用的骨转移影像学检查方法，对骨转移瘤早期即有较高的检出率，辅以X线平片、CT、MRI等手段，有助于进一步提高诊断的准确性。笔者就前列腺癌骨转移的影像学检查的研究现状做一综述，为临床早期诊断骨转移瘤提供影像学依据。

Prostate cancer has a high bone metastasis tendency. At the time of initial diagnosis, there is a high rate of bone metastasis. Early detection of bone metastases in patients with prostate cancer has important significance for staging, treatment and prognosis of prostate cancer. Radionuclide bone imaging（SPECT） is a commonly used imaging examination method of bone metastases, which had a higher detection rate in early bone metastases. Combined with X-ray, CT, MRI and other ways can improve the accuracy of bone metastases. This review summarizes the research status of the imaging examination of bone metastasis of prostate cancer, which provides the imaging evidence for early diagnosis of bone metastases.
