To determine the relation between erythrocyte sedimentation rate and blood echogenicity and whether measurement of erythrocyte sedimentation rate could be replaced by measurement of blood echogenicity in monitoring acute phase reactions.
Simultaneous measurement of echogenicity of flowing blood and erythrocyte sedimentation rate in blood samples and comparison of results.
A radiological department in a university hospital.
83 patients with a suspected venous thrombosis and 36 healthy volunteers.
Correlations between the erythrocyte sedimentation rate, packed cell volume, and echogenicity of flowing blood.
Blood echogenicity correlated poorly with the packed cell volume, but strongly correlated with the erythrocyte sedimentation rate (when the packed cell volume was within reference limits) (correlation coefficient = 0.73). Blood samples with a greatly raised erythrocyte sedimentation rate were highly echogenic. Only one of the 30 samples with an erythrocyte sedimentation rate below 10 mm in first hour had a higher echogenicity than the least echogenic sample of the 19 with a sedimentation rate above 30 mm in first hour.
Echogenicity of flowing blood correlates with the erythrocyte sedimentation rate and its measurement may compete with conventional methods for evaluating the long term changes in acute phase reactions. Also, it has the added advantage that non-invasive in vivo measurements of blood echogenicity may become possible.
确定红细胞沉降率与血液回声性之间的关系，以及在监测急性期反应时红细胞沉降率的测量是否可被血液回声性的测量所取代。
同时测量血样中流动血液的回声性和红细胞沉降率，并比较结果。
一所大学医院的放射科。
83例疑似静脉血栓形成患者和36名健康志愿者。
红细胞沉降率、血细胞比容与流动血液回声性之间的相关性。
血液回声性与血细胞比容的相关性较差，但与红细胞沉降率密切相关（当血细胞比容在参考范围内时）（相关系数=0.73）。红细胞沉降率大幅升高的血样回声性很高。在第一小时红细胞沉降率低于10mm的30个样本中，只有1个样本的回声性高于第一小时沉降率高于30mm的19个样本中回声性最低的样本。
流动血液的回声性与红细胞沉降率相关，其测量可能与评估急性期反应长期变化的传统方法相竞争。此外，它还有一个额外的优势，即有可能实现血液回声性的非侵入性体内测量。
