摘要

背景:我们旨在比较多载体计算机断层扫描(MDCT)和锥束计算机断层扫描(CBCT)在高(HR)和低(LR)分辨率模式下评估鼻腔和副鼻窦的诊断质量:这项体外研究使用 CBCT 和 MDCT 扫描仪在高分辨率和低分辨率模式下对 5 个干燥的人类头骨进行扫描,以评估它们对鼻腔 21 个解剖标志的诊断质量。图像质量由两名口腔颌面放射科医生和一名牙科医生使用李克特四点量表进行评估,即(I)差、(II)较差、(III)好和(IV)优。数据采用 STATA 进行分析,置信区间为 95%。采用卡方检验比较不同扫描仪类型的地标显示质量:结果:HR CBCT 和 CT 对大多数地标的诊断质量高于 LR CBCT 和 CT(PP=0.010)、嗅裂(P=0.032)、蝶窦凹(P=0.032)和鼻泪管(P=0.014),而 LR CBCT 对中鼻甲(P=0.046)和中鼻肉(P=0.031)的诊断质量明显高于 MDCT:结论:HR CBCT 和 CT 对鼻腔和副鼻窦大部分地标的诊断质量高于 LR CBCT 和 CT。对于大多数地标,CBCT 和 CT 的诊断质量相同;而对于某些地标,HR 和 LR CBCT 的诊断质量高于 HR 和 LR CT。总的来说,CBCT 对鼻旁窦和鼻腔的评估具有很高的疗效,所提供的诊断信息与 CT 相当,但辐射剂量要低得多。

Comparison of Diagnostic Quality of Multidetector Computed Tomography and Cone-Beam Computed Tomography in High and Low Resolution Modes for Assessment of the Nasal Cavity.

Background: We aimed to compare the diagnostic quality of multidetector computed tomography (MDCT) and cone-beam computed tomography (CBCT) in high (HR) and low (LR) resolution modes for assessment of the nasal cavity and paranasal sinuses.

Methods: This in vitro study was conducted on 5 dry human skulls by using a CBCT and a MDCT scanner in HR and LR modes to assess their diagnostic quality for 21 anatomical landmarks of the nose. The quality of images was evaluated by two oral and maxillofacial radiologists and a dentist using a four-point Likert scale of (I) poor, (II) decreased, (III) good, and (IV) excellent. Data were analyzed by STATA at 95% confidence interval. The Chi-square test was applied to compare the quality of visualization of landmarks based on the type of scanner.

Results: The diagnostic quality of HR CBCT and CT for the majority of landmarks was higher than that of LR CBCT and CT (P<0.05). The diagnostic quality of HR CBCT for agger nasi cells (P=0.010), olfactory cleft (P=0.032), sphenoethmoidal recess (P=0.032), and nasolacrimal duct (P=0.014) and LR CBCT for the middle turbinate (P=0.046) and middle meatus (P=0.031) was significantly higher than that of MDCT.

Conclusion: The diagnostic quality of HR CBCT and CT for the majority of the landmarks in the nasal cavity and paranasal sinuses was higher than that of LR CBCT and CT. For the majority of landmarks, the diagnostic quality of CBCT and CT was the same; while for some landmarks, the diagnostic quality of HR and LR CBCT was higher than HR and LR CT. In general, CBCT has high efficacy for evaluation of the paranasal sinuses and the nasal cavity, and provides diagnostic information comparable to those provided by CT, but with a much lower radiation dose.
