The ability of different MRI sequences to depict characteristic findings suggestive of ventriculitis was compared.
The study comprised 20 brain MRI studies in 13 patients who had a final diagnosis of ventriculitis. Both diffusion-weighted imaging and FLAIR imaging were equally and highly sensitive for detecting intraventricular debris and pus--the most common MRI finding suggestive of ventriculitis. FLAIR imaging was superior to contrast-enhanced T1-weighted imaging for depicting ventricular wall abnormalities--a less common finding that also is suggestive of ventriculitis.
比较不同MRI序列描绘提示脑室炎特征性表现的能力。
该研究纳入了13例最终诊断为脑室炎患者的20份脑部MRI检查。弥散加权成像和液体衰减反转恢复序列成像在检测脑室内碎片和脓液方面同样具有高度敏感性，这是提示脑室炎最常见的MRI表现。在描绘脑室壁异常方面，液体衰减反转恢复序列成像优于增强T1加权成像，脑室壁异常是提示脑室炎的一种较不常见的表现。
