AIM
To differentiate two common aetiologies of "ring lesions," tuberculomas and cysticercal cysts, using T2 relaxometry.
MATERIALS AND METHODS
Fifty-five ring-enhancing lesions of the brain (32 cysticercal cysts; 23 tuberculomas) in 27 patients with focal seizures were studied for T2 relaxation times.
RESULTS
The mean T2 relaxation times of cysticercal cysts was 617 ms (range 305-1365 ms; SD 272.2) and that of tuberculomas 161 ms (range 83-290 ms; SD 60.3; 95% confidence).
CONCLUSION
T2 relaxometry is a simple, reliable and valuable non-invasive magnetic resonance imaging (MRI) technique to differentiate between intracranial cysticercal cysts and tuberculomas, and may be incorporated in routine diagnostic protocols.
目的
使用T2弛豫测量法鉴别“环形病变”的两种常见病因，即结核瘤和囊尾蚴囊肿。
材料与方法
对27例局灶性癫痫患者脑内的55个环形强化病变（32个囊尾蚴囊肿；23个结核瘤）进行T2弛豫时间研究。
结果
囊尾蚴囊肿的平均T2弛豫时间为617毫秒（范围305 - 1365毫秒；标准差272.2），结核瘤的平均T2弛豫时间为161毫秒（范围83 - 290毫秒；标准差60.3；95%置信区间）。
结论
T2弛豫测量法是一种简单、可靠且有价值的非侵入性磁共振成像（MRI）技术，可用于鉴别颅内囊尾蚴囊肿和结核瘤，并且可纳入常规诊断方案。
