Thirty-seven gallium-67 images were reviewed retrospectively to determine relative renal gallium activity ( RGA ) in patients with no evidence of renal disease. Twenty-four patients were classified as having no evidence of renal disease (NRD). RGA was identified in 50.0% (12/24) of patients in the NRD group. We conclude that the presence of RGA neither suggests nor rules out renal disease. Altered nonrenal biological factors (such as saturation of iron-binding capacity) may decrease soft-tissue gallium accumulation while activity in the kidney remains unchanged. The latter provides renal images with better signal-to-noise ratio. Current imaging equipment may allow renal visualization in these patients.
对37例镓-67图像进行回顾性分析，以确定无肾脏疾病证据患者的相对肾镓活性（RGA）。24例患者被分类为无肾脏疾病证据（NRD）。NRD组中50.0%（12/24）的患者发现有RGA。我们得出结论，RGA的存在既不提示也不排除肾脏疾病。非肾脏生物学因素的改变（如铁结合能力饱和）可能会减少软组织中的镓蓄积，而肾脏中的活性保持不变。后者可提供具有更好信噪比的肾脏图像。当前的成像设备可能使这些患者的肾脏显影。
