The objective of this retrospective study was to identify and categorize incidental findings (IFs) discovered on limited field of view (LFOV) cone beam computed tomographic (CBCT) scans of the maxillofacial region. The sequential LFOV CBCT radiology reports created by 2 board-certified radiologists from January 1, 2017, to December 31, 2017, were retrospectively reviewed. The CBCT scans were acquired for implant site evaluation. Incidental findings of pathologic or anatomical defects were categorized as endodontic, periodontal, sinus-related, nonodontogenic, or other concerns. Of 474 radiology reports that were evaluated, 244 (51.5%) recorded at least 1 detectable IF. Fifty-one of these 244 (10.8% of the total sample) recorded that multiple IFs were detected on a single CBCT scan. On 3 reports, 3 IFs were detected, while the remaining 48 reports showed 2 IFs. More than half of the 295 unique IFs were categorized as endodontic or sinus-related concerns. The majority (70.5%) of IFs were recommended for referral or additional treatment. The results indicate that the use of a CBCT system with an LFOV does not diminish the need to conduct a thorough evaluation of the images.
本回顾性研究旨在识别和分类颌面区域小视野（LFOV）锥形束 CT（CBCT）扫描中偶然发现的（IF）。对 2017 年 1 月 1 日至 2017 年 12 月 31 日期间由 2 位经过董事会认证的放射科医生创建的连续 LFOV CBCT 放射学报告进行了回顾性审查。这些 CBCT 扫描是为评估种植部位而采集的。偶然发现的病理或解剖缺陷被归类为牙髓、牙周、窦相关、非牙源性或其他问题。在评估的 474 份放射学报告中，有 244 份（51.5%）记录了至少 1 个可检测的 IF。在这 244 份报告中，有 51 份（总样本的 10.8%）记录了在单次 CBCT 扫描中检测到多个 IF。在 3 份报告中，检测到 3 个 IF，而其余 48 份报告显示 2 个 IF。295 个独特 IF 中超过一半被归类为牙髓或窦相关问题。大多数（70.5%）的 IF 被建议转诊或进一步治疗。结果表明，使用具有 LFOV 的 CBCT 系统并不会减少对图像进行全面评估的必要性。
