【摘要】 目的 评价3D-FFE薄层增强扫描在脑囊虫病定性诊断中的意义。 方法 通过对238例脑囊虫病患者常规序列扫描(即T 1 WI/SE、T 2 WI/TSE、FLAIR、T 1 WI/SE增强扫描)及3DFFE薄层双倍量增强扫描，比较T 1 WI/SE增强扫描及3DFFE薄层增强扫描图像的信躁比，病变与脑灰质的对比噪声比及病灶的对比噪声比以及病变检出率、头节检出率进行对比。 结果 3DFFE/T 1 WI薄层增强扫描的SNR高于T 1 WI/SE增强扫描，脑灰白质对比噪声比低于T 1 WI/SE增强扫描，对于病变的检出、头节检出及多环征的检出，3D-FFE/T 1 WI薄层增强扫描明显高于T 1 WI/SE增强扫描。 结论 3D-FFE薄层增强扫描，能大大提高囊虫检出率及定性诊断率，可作为脑囊虫病检查的常规序列。
