A study was undertaken to determine whether or not intravenous MR arthrography can be used in clinical practice. Forty patients with internal derangement of the knee (11-68 years old) were imaged with MRI before and after intravenous injection of Gd-DTPA. In all knees there was enhancement of joint fluid, regardless of the amount of fluid. The peak enhancement of joint fluid was reached at 30 minutes after the administration of the contrast agent. The contrast between joint fluid and meniscus/cartilage was higher in MR arthrography than in proton density images. There was an increase in contrast between grade III lesions in the meniscus and intact meniscus on MR arthrography. It was concluded that intravenous MR arthrography can be a useful alternative to intra-articular arthrography.
开展了一项研究以确定静脉内磁共振关节造影术是否可用于临床实践。40例膝关节内部紊乱患者(年龄11 - 68岁)在静脉注射钆喷酸葡胺前后接受了磁共振成像检查。在所有膝关节中,无论关节液量多少,关节液均有强化。关节液的强化峰值在注射造影剂后30分钟达到。磁共振关节造影术中关节液与半月板/软骨之间的对比度高于质子密度图像。在磁共振关节造影术中,半月板III级损伤与完整半月板之间的对比度有所增加。得出的结论是,静脉内磁共振关节造影术可成为关节内造影术的一种有用替代方法。
