A retrospective study was carried out to determine the prevalence of abnormality in the paranasal sinuses in a British population having magnetic resonance imaging (MRI) scans for neurological signs and symptoms. The T2-weighted scans of 130 patients were studied. Abnormalities in the paranasal sinuses show as high signal on the T2-weighted scans and thus are clearly seen. Abnormalities included mucosal thickening, fluid levels, sinus opacification and retention cysts/polyps. Of the patients studied, 49.2 per cent showed one or more abnormality. Mucosal thickening was the most common abnormality noted and the ethmoid sinuses the most commonly affected.
开展了一项回顾性研究，以确定因神经系统体征和症状而接受磁共振成像（MRI）扫描的英国人群中鼻窦异常的患病率。对130例患者的T2加权扫描进行了研究。鼻窦异常在T2加权扫描上表现为高信号，因此清晰可见。异常包括黏膜增厚、液平面、鼻窦混浊和潴留囊肿/息肉。在所研究的患者中，49.2%表现出一种或多种异常。黏膜增厚是最常见的异常表现，筛窦是最常受累的鼻窦。
