To correlate the features of inflammatory changes in the paranasal sinuses on magnetic resonance imaging (MRI) with computed tomography (CT).
One hundred and fourteen patients with histologically proven nasopharyngeal carcinoma (NPC) were staged with both CT and MRI. All CT and MRI images of patients with mucosal thickening but no tumour involvement of the sinuses were retrospectively analysed.
There were inflammatory changes in 36 maxillary, 21 sphenoid and 16 ethmoid sinuses. These changes include mucosal thickening, retention cysts, retained secretions, inspissated secretions and dystrophic calcification. MRI is superior to CT in separating thickened mucosa, retained secretions and retentions cysts.
It is important to appreciate CT changes of sinusitis and the corresponding spectrum of MRI features.
将鼻窦炎性改变在磁共振成像（MRI）上的特征与计算机断层扫描（CT）进行关联。
114例经组织学证实的鼻咽癌（NPC）患者同时接受CT和MRI分期。对所有鼻窦有黏膜增厚但无肿瘤累及的患者的CT和MRI图像进行回顾性分析。
36个上颌窦、21个蝶窦和16个筛窦存在炎性改变。这些改变包括黏膜增厚、潴留囊肿、潴留分泌物、浓缩分泌物和营养不良性钙化。在区分增厚的黏膜、潴留分泌物和潴留囊肿方面，MRI优于CT。
认识鼻窦炎的CT改变及相应的MRI特征谱很重要。
