Seventy-five patients with a wide range of sinus disease have been investigated by magnetic resonance (MR): these included congenital conditions, allergic and inflammatory sinus disease, fungus infections, and the necrotizing granulomata. In addition, a variety of benign and malignant tumours have been examined, and in the more recent sinus malignancies the paramagnetic contrast agent, Gadolinium (Gd) DTPA (Schering Health Care) has been used. This experience of magnetic resonance scanning has shown that it is superior to computed tomography in demonstrating the extent of malignant disease in the nose and sinuses; most especially when Gd DTPA is used, reaching an accuracy of over 96% by biopsy correlation. An additional advantage of this technique is the wide coverage of the head and neck for the assessment of malignant disease, provided by direct 3 plane imaging and the multislice facility. The main disadvantage of magnetic resonance of the sinuses is the poor demonstration of calcification and bone. For this reason the MR scans may need to be augmented by high resolution CT performed specifically to show bone detail.
75名患有各种鼻窦疾病的患者接受了磁共振(MR)检查:这些疾病包括先天性疾病、过敏性和炎症性鼻窦疾病、真菌感染以及坏死性肉芽肿。此外,还检查了各种良性和恶性肿瘤,在最近的鼻窦恶性肿瘤检查中使用了顺磁性造影剂钆(Gd)二乙三胺五乙酸(Gd DTPA,先灵葆雅医疗保健公司生产)。磁共振扫描的经验表明,在显示鼻和鼻窦恶性疾病的范围方面,它优于计算机断层扫描;尤其是使用Gd DTPA时,经活检相关性验证,准确率超过96%。该技术的另一个优点是,通过直接的三平面成像和多层扫描设备,对头颈部进行广泛覆盖,以评估恶性疾病。鼻窦磁共振成像的主要缺点是对钙化和骨质的显示不佳。因此,可能需要通过专门为显示骨质细节而进行的高分辨率CT来补充MR扫描。
