Radionuclide arthrography of the knee is described using Tc-99m sulfur colloid, which is injected into the synovial cavity following partial distension of the joint space with saline. The preliminary findings in Baker's cyst are described. There appear to be four patterns: 1) a herniation or cyst that can be posterior, inferior, medial or lateral to the knee synovial space; 2) a limited leak inferiorly toward the calf or superiorly toward the thigh; 3) extensive leak: giant cyst found in patients with rheumatoid arthritis; 4) multiple "cysts" or communications with the knee synovial space. The series is small, and more work is needed before these preliminary findings can be used as firm categories. Radionuclide arthrography should be considered in patients with unexplained calf pain or pain behind the knee, especially with a history of previous internal knee derangement, or rheumatoid arthritis in whom ruptured cysts can closely mimic acute thrombophlebitis. Radionuclide arthrography has certain advantages over contrast arthrography and also arthroscopy in the diagnosis of Baker's cyst.
本文描述了使用锝-99m硫胶体进行膝关节放射性核素关节造影的方法，即在关节腔用盐水部分扩张后，将其注入滑膜腔。文中描述了腘窝囊肿的初步检查结果。似乎有四种类型：1）疝或囊肿，可位于膝关节滑膜腔的后方、下方、内侧或外侧；2）向小腿下方或大腿上方的局限性渗漏；3）广泛渗漏：类风湿关节炎患者中发现的巨大囊肿；4）多个“囊肿”或与膝关节滑膜腔相通。该系列病例数量较少，在这些初步检查结果可作为确定的类别使用之前，还需要更多的研究。对于不明原因的小腿疼痛或膝关节后方疼痛的患者，尤其是有既往膝关节内部紊乱病史或类风湿关节炎的患者，应考虑进行放射性核素关节造影，因为破裂的囊肿可能与急性血栓性静脉炎极为相似。放射性核素关节造影在腘窝囊肿的诊断方面比造影剂关节造影和关节镜检查具有某些优势。
