Diagnostic difficulties in discriminating brain abscess from necrotic or cystic tumors using conventional CT and MRI have been reported. In this article, we examine the diagnostic ability of diffusion-weighted imaging to discriminate brain abscess from necrotic or cystic tumors. In previous reports, necrotic or cystic tumors show low signal intensity in diffusion-weighted imaging, indicating a high apparent diffusion coefficient (ADC). In contrast, in our study, high signal intensity was observed in the abscess fluid, associated with low ADC.
据报道，使用传统CT和MRI鉴别脑脓肿与坏死性或囊性肿瘤存在诊断困难。在本文中，我们研究了扩散加权成像鉴别脑脓肿与坏死性或囊性肿瘤的诊断能力。在以往的报道中，坏死性或囊性肿瘤在扩散加权成像中表现为低信号强度，表明表观扩散系数（ADC）较高。相比之下，在我们的研究中，脓肿液中观察到高信号强度，伴有低ADC。
