T2-weighted magnetic resonance imaging (MRI) presents paranasal sinus pathology with remarkable clarity. However, it has yet to be demonstrated that all MRI findings represent true pathology and not minor or incidental findings of no consequence. In an effort to resolve this question, we have analysed retrospectively 263 consecutive T2-weighted MRI examinations of the head performed for indications not associated with possible sinus pathology. We examined these studies for abnormally increased signal in the paranasal sinuses and the sites of involvement. Mucoperiosteal thickening, mucus retention cysts, air-fluid levels or total sinus opacification were recorded. Of the 263 studies examined, 65 (24.7%) demonstrated abnormalities in the paranasal sinuses. We conclude that because of its great sensitivity MRI will often detect abnormalities in the paranasal sinuses which are unrelated to the patients' presenting problems.
T2加权磁共振成像（MRI）能非常清晰地显示鼻窦病变。然而，目前尚未证实所有的MRI表现均代表真正的病变，而非无临床意义的轻微或偶然发现。为了解决这一问题，我们回顾性分析了连续263例因与鼻窦病变无关的指征而行头部T2加权MRI检查的病例。我们检查这些研究中鼻窦内异常增高的信号及受累部位。记录黏膜骨膜增厚、黏液潴留囊肿、气液平面或鼻窦完全混浊的情况。在检查的263例研究中，65例（24.7%）显示鼻窦有异常。我们得出结论，由于MRI敏感性高，它常常会检测到与患者当前问题无关的鼻窦异常。
