Blood and blood products, and solutions of albumin and chondroitin sulfate of varying concentrations were imaged by ultrasound and computed tomography in a phantom having ultrasonic and CT characteristics of liver tissue. Measurements of CT number, ultrasonic absorption, and viscosity were obtained for selected fluids. All fluids, including concentrated solutions of albumin and chondroitin sulfate having high viscosity, were detectable as echofree regions on ultrasound scans. Acoustical enhancement distal to fluids was noted to decrease in prominence with increasing sound absorption in the fluid. On CT scans, fluids with CT numbers close to those of their surroundings were poorly detected.
在具有肝脏组织超声和CT特征的模型中，对血液、血液制品以及不同浓度的白蛋白和硫酸软骨素溶液进行了超声和计算机断层扫描成像。对选定的液体进行了CT值、超声吸收和粘度的测量。所有液体，包括具有高粘度的白蛋白和硫酸软骨素浓缩溶液，在超声扫描中均被检测为无回声区。随着液体中声音吸收的增加，液体远端的声学增强在突出程度上有所降低。在CT扫描中，CT值与其周围环境接近的液体很难被检测到。
