Computed tomography has greatly improved the accuracy of sinus imaging. While contiguous coronal computed tomography scanning of the sinuses provides detailed imaging as compared with plain sinus radiography, this modality is significantly more expensive and involves exposure of the patient to a higher dose of radiation. It has become increasingly common to obtain screening, or non-contiguous, CT scans of the sinuses when screening for the presence of sinusitis.
To calculate the sensitivity and specificity of the screening coronal CT scan of the sinuses in screening for inflammatory disease using the contiguous coronal CT examination of the sinuses as the standard.
From contiguous coronal computed tomograms of the paranasal sinuses, screening coronal computed tomographic examinations were created for 44 patients. Patients were being screened for the presence of sinusitis in the Comprehensive Sinus Clinic at St. Louis University. The two examinations were reviewed independently and in random order by two neuroradiologists. Using the original examinations as the standard, the sensitivity and specificity of the screening studies were calculated for various situations.
Overall, a sensitivity of 93.3% and a specificity of 89.3% for the detection of inflammatory disease of the sinuses by the screening examination was observed.
The screening coronal computed tomogram of the paranasal sinuses may be useful in the evaluation of the patient with possible sinusitis.
计算机断层扫描极大地提高了鼻窦成像的准确性。与普通鼻窦X线摄影相比，鼻窦连续冠状位计算机断层扫描能提供详细的影像，但这种检查方式成本显著更高，且患者所接受的辐射剂量也更大。在筛查鼻窦炎时，获取鼻窦的筛查性（即非连续的）CT扫描已变得越来越普遍。
以鼻窦连续冠状位CT检查作为标准，计算鼻窦筛查性冠状位CT扫描在筛查炎症性疾病时的敏感性和特异性。
从44例患者的鼻窦连续冠状位计算机断层扫描图像中生成筛查性冠状位计算机断层扫描图像。这些患者在圣路易斯大学综合鼻窦诊所接受鼻窦炎筛查。两名神经放射科医生独立且随机地对这两种检查进行评估。以原始检查作为标准，计算筛查性研究在各种情况下的敏感性和特异性。
总体而言，筛查性检查对鼻窦炎症性疾病检测的敏感性为93.3%，特异性为89.3%。
鼻窦筛查性冠状位计算机断层扫描在评估可能患有鼻窦炎的患者时可能有用。
