Figure 7: Axial image from CT cisternogram demonstrates intrathecal contrast leaking into the expanded right sphenoid sinus along the septum (orange arrow).
图7：轴位CT脑池造影显示硬膜下造影剂沿着中隔渗漏到扩张的右侧蝶窦腔内。
Methods Axial and coronal scan the paranasal sinus for 271 patients, to analyze the types and areas of paranasal sinus diseases.
方法对271例患者行副鼻窦轴扫和冠扫，分析副鼻窦疾病病变的类型、范围。
Purpose To select the best scanning method for accessory sinus lesions by comparing the advantages with the disadvantages of ct axial films and coronal films.
目的：分析副鼻窦病变CT扫描轴位片与冠状位片的优劣，探讨鼻窦扫描方法的最佳选择。
Figure 2: T2-weighted axial image once again demonstrates a large, heterogeneous lesion located in the ethmoidal sinus (arrow). The lesion is predominately isointense to grey matter.
图2：T2序列轴位影像再次显示一个大的不均匀病变，位于筛窦（箭头）。病变的信号类似于灰质。
Methods In the contrast study, CT axial scanning plus reconstruction was performed in 45 randomized cases and so was coronal scanning in 45 randomized cases of accessory sinus lesions.
方法：分别对随机分组的副鼻窦病变采用轴位加重建45例，冠状位45例，进行扫描，对比其对诊断的优越性。
Methods:8 cases with maxillary sinus aspergillosis were proformed by surgical speciment and histological examination. All were examinated by stand or sited position X-ray plain film and axial CT scan.
方法：经手术和病理诊断的上颌窦曲菌病8例，均照有站立或坐位平片和轴位CT扫描。
