The echogenicity of clotting human blood in sterile plastic bags was studied for up to 21 days and correlated with the histology of the clots. As observed with a 6-MHz A-scanner and a 5-MHz real-time gray-scale scanner, fresh blood and fresh clots were rich in internal echoes. The blood clot gradually became anechoic as a result of erythrocyte packing, hemolysis, and formation of fibrin thrombus, except for the irregular upper border, which also remained histologically inhomogeneous. This study shows that the echogenicity of a hematoma or clot is dependent on its histology; namely, on the distribution and integrity of cells within the clot.
对无菌塑料袋中凝固的人体血液的回声特性进行了长达21天的研究，并与血栓的组织学进行了关联。使用6兆赫A扫描仪和5兆赫实时灰阶扫描仪观察到，新鲜血液和新鲜血栓内部回声丰富。由于红细胞堆积、溶血和纤维蛋白血栓形成，血凝块逐渐变为无回声，但不规则的上边界除外，其在组织学上也保持不均匀。这项研究表明，血肿或血栓的回声特性取决于其组织学；也就是说，取决于血栓内细胞的分布和完整性。
