Magnetic resonance imaging is able to demonstrate a wide range of sinus abnormalities. Incidental findings in patients referred for neuroradiology because of suspected intracranial pathology are surprisingly common and were present in 37.5 per cent of 483 images examined. The maxillary and ethmoid sinuses were most commonly affected with 27 and 26 per cent of images abnormal whereas the frontal and sphenoid sinuses were less commonly affected with 5 per cent of each abnormal. If minor changes were excluded then 17 per cent of patients had either fluid, a polyp or marked mucosal thickening in at least one sinus. Nasal symptoms, other than the presence of a cold, showed no statistically significant relationship to abnormal findings. Many people with inflammatory changes in their sinuses demonstrated on MRI do not have symptoms classically attributed to sinusitis.
磁共振成像能够显示多种鼻窦异常情况。因疑似颅内病变而转诊至神经放射科的患者中，偶然发现的鼻窦异常情况出奇地常见，在检查的483份影像中，有37.5%出现了这种情况。上颌窦和筛窦受影响最为常见，分别有27%和26%的影像显示异常，而额窦和蝶窦受影响较少，各有5%的影像显示异常。如果排除轻微变化，那么17%的患者至少有一个鼻窦出现积液、息肉或明显的黏膜增厚。除了感冒外，鼻部症状与异常发现之间没有统计学上的显著关联。许多鼻窦在磁共振成像上显示有炎症变化的人并没有典型的鼻窦炎症状。
