Augmented reality navigation system for percutaneous computed tomography (CT)-guided pulmonary biopsies has recently been introduced. There are no studies in literature about its use for ground glass lesions biopsies. The aim of this study is to evaluate the effectiveness of an augmented reality infrared navigation system performance on CT-guided percutaneous lung ground glass opacity (GGO) biopsy compared to a standard CT-guided technique.
A total of 80 patients with lung GGO who underwent to a percutaneous CT-guided lung biopsy with an augmented reality infrared navigation system were retrospectively enrolled in the study. Comparison was performed with a group of 80 patients who underwent to lung biopsy with the standard CT-guided technique. Evaluation of maximum lesion diameter (MLD), distance between lesion and pleural surface (DPS), distance travelled by the needle (DTP), procedural time, validity of histological sample, procedural complications and the radiation dose to the patient's chest were recorded for each patient of both groups. In addition, each group was divided into two subgroups based on lesion size, according to a cut-off of 1.5 cm (<1.5 cm; ≥1.5 cm).
Augmented reality navigation system showed a significant reduction in procedural time, radiation dose administrated to patients and complications rate compared to a standard CT-guided technique. Technical success was achieved in the 100% of cases in both groups, but the diagnostical success was higher in the group where patients underwent to lung biopsies with the use of navigation system. We also found that using an augmented reality navigation system increases the diagnostical success rate for lesion <1.5 cm. MLD, DPS and DTP did not differ significantly between the two groups of patients.
The use of an augmented reality navigation system for percutaneous CT-guided pulmonary GGO biopsies has demonstrated a lower incidence of post-procedural complications, a significantly reduction of the radiation dose administered to patients and a higher diagnostical success rate.
经皮计算机断层扫描（CT）引导下肺活检的增强现实导航系统最近已被引入。文献中尚无关于其用于磨玻璃病变活检的研究。本研究的目的是评估与标准CT引导技术相比，增强现实红外导航系统在CT引导下经皮肺磨玻璃密度影（GGO）活检中的有效性。
本研究回顾性纳入了80例行增强现实红外导航系统引导下经皮CT引导肺活检的肺GGO患者。与一组80例行标准CT引导技术肺活检的患者进行比较。记录两组每位患者的最大病变直径（MLD）、病变与胸膜表面的距离（DPS）、穿刺针行进的距离（DTP）、操作时间、组织学样本的有效性、操作并发症以及患者胸部的辐射剂量。此外，根据1.5 cm的截断值（<1.5 cm；≥1.5 cm），每组患者又分为两个亚组。
与标准CT引导技术相比，增强现实导航系统在操作时间、给予患者的辐射剂量和并发症发生率方面均有显著降低。两组病例的技术成功率均为100%，但在使用导航系统进行肺活检的组中诊断成功率更高。我们还发现，使用增强现实导航系统可提高<1.5 cm病变的诊断成功率。两组患者的MLD、DPS和DTP无显著差异。
在经皮CT引导下肺GGO活检中使用增强现实导航系统已证明术后并发症发生率较低，给予患者的辐射剂量显著降低，诊断成功率更高。
