Vibration white finger is a vasospastic disorder caused by long-term exposure to vibration tools. In an attempt to assess the extent of obliterative vessel disease in this disorder, hyperaemic hand blood flow was measured using technetium-labelled human albumin and a gamma camera. This method quantitates blood flow in ml/100 ml of tissue per min in addition to providing a perfusion image used to assess vessel disease. A perfusion score is then given to this image to reflect the extent of disease. The results of this study demonstrate that 78% of patients with vibration white finger had evidence of organic vessel disease. Moreover, patients with advanced disease tend to be bilaterally affected. The use of this simple method is advocated to aid in the diagnosis of vibration white finger; this may be particularly important for medicolegal purposes.
振动性白指是一种由长期接触振动工具引起的血管痉挛性疾病。为了评估这种疾病中闭塞性血管疾病的程度，使用锝标记的人白蛋白和γ相机测量了手部充血血流量。这种方法除了提供用于评估血管疾病的灌注图像外，还能以每分钟每100毫升组织中毫升数来定量血流量。然后给该图像一个灌注评分以反映疾病的程度。这项研究的结果表明，78%的振动性白指患者有器质性血管疾病的证据。此外，病情较重的患者往往双侧受累。提倡使用这种简单方法来辅助诊断振动性白指；这对于法医学目的可能尤为重要。
