A case is presented where skeletal metastases from a prostate carcinoma were detected during 99mTc DTPA scintigraphy performed for evaluation of renal function. The lumbar vertebrae in camera field of view were intensely perfused on the arterial phase of the radionuclide flow study. Tracer pooling in these vertebrae, visualized on initial serial images, progressively faded over the 30 minute study. Widespread areas of increased radionuclide uptake, consistent with skeletal metastases, were detected on 99mTc MDP bone imaging performed two days later. Subsequent prostatic biopsy revealed a well differentiated primary adenocarcinoma.
本文报告一例在进行99mTc DTPA肾动态显像以评估肾功能时，发现前列腺癌骨转移的病例。在放射性核素血流研究的动脉期，相机视野内的腰椎有强烈的灌注。在最初的系列图像上可见这些椎体有示踪剂聚集，在30分钟的检查过程中逐渐消退。两天后进行的99mTc MDP骨显像发现广泛的放射性核素摄取增加区域，符合骨转移表现。随后的前列腺活检显示为高分化原发性腺癌。
