To develop a new method of magnetic resonance arthrography (MRA) of the knee using an anterior approach analogous to the portals used for knee arthroscopy.
An anterior approach to the knee joint was devised mimicking anterior portals used for knee arthroscopy. Seven patients scheduled for routine knee MRA were placed in a decubitus position and under fluoroscopic guidance a needle was advanced from a position adjacent to the patellar tendon into the knee joint. After confirmation of the needle tip location, a dilute gadolinium solution was injected.
All the arthrograms were technically successful. The anterior approach to knee MRA has greater technical ease than the traditional approach with little patient discomfort.
开发一种膝关节磁共振关节造影（MRA）的新方法，采用类似于膝关节镜检查所用入口的前入路。
设计了一种膝关节前入路，模仿膝关节镜检查所用的前入口。7例计划进行常规膝关节MRA的患者取卧位，在透视引导下，将一根针从髌腱附近的位置推进膝关节。确认针尖位置后，注入稀释的钆溶液。
所有关节造影在技术上均获成功。膝关节MRA的前入路在技术上比传统入路更容易，患者不适感小。
