Abstract

Background: Temporal bone computed tomography delivers a relatively high radiation dose. Cone beam computed tomography could be a promising alternative, offering good performance with reduced radiation exposure. This study aimed to compare the irradiation during temporal bone imaging using computed tomography versus cone beam computed tomography.

Materials and methods: We conducted a single-centre prospective study evaluating dosimetric data collected from patients undergoing temporal bone imaging via computed tomography or cone beam computed tomography. Absorbed doses (milligrays) were measured using mini-dosimeters placed on key anatomical sites: eyes, ears, lower neck and pubic region, and compared between the two imaging modalities.

Results: CBCT significantly reduced radiation, with absorbed doses being two to six times lower than those observed with conventional computed tomography, depending on the measured sites.

Conclusion: Our findings align with existing literature, confirming the reduced irradiation with cone beam computed tomography in ear imaging. Further studies are warranted to evaluate image quality relative to radiation dose between the two techniques.

锥形束与多探测器扫描仪辐照耳部成像的比较。

背景：颞骨计算机断层扫描的辐射剂量相对较高。锥束计算机断层扫描可能是一种很有前途的替代方法，在减少辐射暴露的情况下提供良好的性能。本研究的目的是比较在颞骨成像中使用计算机断层扫描和锥形束计算机断层扫描的照射。材料和方法：我们进行了一项单中心前瞻性研究，评估了通过计算机断层扫描或锥束计算机断层扫描接受颞骨成像的患者收集的剂量学数据。吸收剂量（毫克）是通过放置在关键解剖部位的微型剂量计测量的：眼睛、耳朵、下颈部和阴部，并比较两种成像方式。结果：CBCT显着减少了辐射，吸收剂量比传统计算机断层扫描观察到的剂量低2至6倍，具体取决于测量部位。结论：我们的研究结果与现有文献一致，证实了圆锥束计算机断层扫描在耳成像中的减少照射。需要进一步的研究来评估两种技术之间相对于辐射剂量的图像质量。

期刊介绍： The Journal of Laryngology & Otology (JLO) is a leading, monthly journal containing original scientific articles and clinical records in otology, rhinology, laryngology and related specialties. Founded in 1887, JLO is absorbing reading for ENT specialists and trainees. The journal has an international outlook with contributions from around the world, relevant to all specialists in this area regardless of the country in which they practise. JLO contains main articles (original, review and historical), case reports and short reports as well as radiology, pathology or oncology in focus, a selection of abstracts, book reviews, letters to the editor, general notes and calendar, operative surgery techniques, and occasional supplements. It is fully illustrated and has become a definitive reference source in this fast-moving subject area. Published monthly an annual subscription is excellent value for money. Included in the subscription is access to the JLO interactive web site with searchable abstract database of the journal archive back to 1887.
