目的利用螺旋CT轴位扫描和多平面重建,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及副鼻窦轴位扫描能否代替直接冠状位扫描。方法将副鼻窦病变254例分成两组,观察组轴位扫描直接观片或多平面重建后再观片,对照组直接采用冠状位扫描。将两组图像分析,对比其诊断的优越性。结果轴位扫描后重组所得图像也能使诊断医师及临床医师从多方位多角度观察,且伪影较少并为患者乐于接受。结论副鼻窦螺旋CT轴位扫描一般可以代替副鼻窦直接冠状位扫描。
Objective To analyze the advantages and disadvantages of CT scan and coronal radiographs of paranasal sinus lesions by using spiral CT axial and multiplanar reconstruction to explore whether the best choice of paranasal sinus scanning and paranasal sinus axial scanning can replace direct coronal scanning . Methods A total of 254 cases of paranasal sinus lesions were divided into two groups. The axial scanning of the observation group was performed either directly or after multiplanar reconstructions. The control group received coronal scanning directly. The two groups of images were analyzed to compare the superiority of their diagnosis. Results The reconstructed images after axial scanning can also enable diagnosticians and clinicians to observe from multiple perspectives with less artifacts and patient acceptance. Conclusions The paranasal sinus CT scan can replace the direct coronal scan of paranasal sinuses.
