回顾了三名健康志愿者髋关节和膝关节的磁共振（MR）图像，并与三名积液患者髋关节的图像进行了比较。还进行了比较，从两个猪膝关节后，在一个注射生理盐水和血液中的其他获得的MR图像。膝关节和髋关节的解剖结构明确。髋关节积液都很容易识别。猪膝关节的MR图像清楚地显示了实验产生的关节积液。髋关节积液和实验引入的血液和生理盐水都具有长T1和T2值，从而易于与关节软骨区分。我们无法区分膝关节内的新鲜血液和生理盐水。
Magnetic resonance (MR) images of the hips and knees of three healthy volunteers were reviewed and compared with images obtained from the hips of three patients with effusions. Comparison was also made with MR images obtained from two swine knees following the injections of saline in one and blood in the other. The anatomy of the knees and hips was well defined. The hip effusions were all easily recognized. MR images of the swine knees clearly demonstrated the experimentally produced joint effusions. The hip effusions and the experimentally introduced blood and saline all had long T1 and T2 values allowing easy differentiation from articular cartilage. We were unable to distinguish fresh blood from saline in the knee joints.
