摘要
目的探究低剂量CT容积扫描联合三维重建对鼻骨骨折患者的诊断效果观察分析。方法回顾性分析我院骨科2020年6月-2022年8月收治鼻骨骨折患者84例,采用数字抽签法将患者平均分成低剂量组(42例),高剂量组(42例)。低剂量组采用低剂量CT容积扫描联合三维重建处理,高剂量组采用高剂量CT容积扫描联合三维重建处理;比较低剂量组和高剂量组患者的扫描时间、CT容积剂量指数、剂量长乘积、有效辐射剂量以及图像质量。结果低剂量组的扫描时间、CT容积剂量指数(mGy)、剂量长乘积(mGy.cn)、有效辐射剂量(mSv)等四个维度均低于高剂量组,差异具备统计学意义(P<0.05)。低剂量组图像优良率(80.95)低于高剂量组(97.62),差异具备统计学意义(P<0.05)。结论低剂量CT扫描联合三维重建技术在诊断鼻骨骨折这一疾病的应用效果良好,有效降低了辐射剂量,图像质量也得到一定保障,提高了患者检查的安全性,值得在临床上广泛使用。
Objective To investigate the effect of low-dose CT volume scanning combined with threedimensional reconstruction in the diagnosis of nasal bone fracture.Methods Retrospective analysis was made on 84 patients with nasal bone fracture treated in our orthopedics department from June 2020 to August 2022.The patients were divided into low dose group(42 cases)and high dose group(42 cases)by digital lottery.Low dose CT volume scanning combined with 3D reconstruction was used in the low-dose group,while high-dose CT volume scanning combined with 3D reconstruction was used in the high-dose group;The scanning time,CT volume dose index,long dose product,effective radiation dose and image quality of patients in low-dose group and highdose group were compared.Results The scanning time,CT volume dose index(mGy),long dose product(mGy.cn),and effective radiation dose(mSv)in the low-dose group were lower than those in the high-dose group,with statistically significant differences(P<0.05).The image excellent rate of low-dose group(80.95)was lower than that of high-dose group(97.62),with a statistically significant difference(P<0.05).Conclusion The application of low-dose CT scanning combined with three-dimensional reconstruction technology in the diagnosis of nasal bone fracture has a good effect,which effectively reduces the radiation dose,ensures the image quality,improves the safety of patient examination,and is worthy of extensive clinical use.
