“…Our results are consistent with previous reports in terms of diagnostic success for PLB [ 20 ]. In a study, which included 180 patients, Grasso et al found a diagnostic success rate of 96% in the navigation group and 90% in the standard group [ 20 ].…”

“…The automatic recording and detection of the magnetic transmitter on the patient’s skin has always been effective and has never prevented the use of the navigation system. In a randomized study on 180 patients using a navigation system based on optical tracking in the field of lung biopsies, Grasso et al found a significant reduction in the procedure time, the number of control scans and the radiation dose [ 20 ]. In another study, this optical navigation system called SIRIO (MASMEC S.p.A., Modugno, BA, Italy) has been shown to be more accurate for percutaneous lung biopsies of lesions <20 mm [ 21 ].…”

“…In order to improve accuracy and limit X-ray exposure, a series of navigational guidance tools have been developed, based on the principle of “augmented reality” [ 1 , 9 ]. These new systems allow electromagnetic [ 2 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 ], or optical tracking of devices [ 19 , 20 , 21 , 22 , 23 ], that are used for interventional radiology or surgical procedures. Data from a previous patient’s scan can be used in a model to perform virtual real time navigation.…”

The aim of our study was to assess the efficacy of a computed tomography (CT)-Navigation™ electromagnetic system compared to conventional CT methods for percutaneous lung biopsies (PLB). In this single-center retrospective study, data of a CT-Navigation™ system guided PLB (NAV-group) and conventional CT PLB (CT-group) performed between January 2017 and February 2020 were reviewed. The primary endpoint was the diagnostic success. Secondary endpoints were technical success, total procedure duration, number of CT acquisitions and the dose length product (DLP) during step ∆1 (from planning to initial needle placement), step ∆2 (progression to target), and the entire intervention (from planning to final control) and complications. Additional parameters were recorded, such as the lesion’s size and trajectory angles. Sixty patients were included in each group. The lesions median size and median values of the two trajectory angles were significantly lower (20 vs. 29.5 mm, p = 0.006) and higher in the NAV-group (15.5° and 10° vs. 6° and 1°; p < 0.01), respectively. Technical and diagnostic success rates were similar in both groups, respectively 95% and 93.3% in the NAV-group, and 93.3% and 91.6% in the CT-group. There was no significant difference in total procedure duration (p = 0.487) and total number of CT acquisitions (p = 0.066), but the DLP was significantly lower in the NAV-group (p < 0.01). There was no significant difference in complication rate. For PLB, CT-Navigation™ system is efficient and safe as compared to the conventional CT method.

“…The results of questionnaire evaluation and electromyography test indicate that ARG can help correct surgeons' poor posture during video-assisted surgery and reduced muscular fatigue of the upper body. More than this, AR performed a good value in the lesion-navigation system (32,48,49) and multi-center joint surgery virtual system (50).…”

“…AR systems map cross-sectional data onto the subject's body; therefore, the interventional operator can visualize the anatomic structures inside the patient. Preclinical investigations have documented the applicability of AR systems for interventional procedures guided with magnetic resonance imaging (3-9), ultrasonography (10,11), and CT (12,13), and early clinical investigations have begun (14). Because the AR described in our study is video based, its use instead of fluoroscopy during cone-beam CT -guided procedures results in a reduction in radiation dose.…”

Purpose To compare the navigational accuracy and radiation dose during needle localization of targets for augmented reality (AR) with and without motion compensation (MC) versus those for cone-beam computed tomography (CT) with real-time fluoroscopy navigation in a pig model. Materials and Methods This study was approved by the Institutional Animal Care and Use Committee. Three operators each localized 15 targets (bone fragments) approximately 7 cm deep in the paraspinal muscles of nine Yorkshire pigs by using each of the three modalities (AR with and without MC and cone-beam CT with fluoroscopy). Target depth, accuracy (distance between needle tip and target), and radiation dose (dose-area product [DAP]) were recorded for each procedure. Correlation between accuracy and depth of target was assessed by using the Pearson correlation coefficient. Two-way analysis of variance was used for differentiating accuracy and DAPs across navigation techniques and operator backgrounds. Results There was no correlation between depth of target and accuracy. There was no significant difference in accuracy between modalities (mean distance, 3.0 mm ± 1.9 [standard deviation] for cone-beam CT with fluoroscopy, 2.5 mm ± 2.0 for AR, and 3.2 mm ± 2.7 for AR with MC [P = .33]). There was, however, a significant difference in fluoroscopy radiation dose (10.4 Gy · cm(2) ± 10.6 for cone-beam CT fluoroscopy, 2.3 Gy · cm(2) ± 2.4 for AR, and 3.3 Gy · cm(2) ± 4.6 for AR with MC [P < .05]) and therefore in total procedural radiation dose (20.5 Gy · cm(2) ± 13.4 for cone-beam CT fluoroscopy, 12.6 Gy · cm(2) ± 5.3 for AR, 13.6 Gy · cm(2) ± 7.4 for AR with MC [P < .05]). Conclusion Use of an AR C-arm system reduces radiation dose while maintaining navigational accuracy compared with cone-beam CT fluoroscopy during image-guided percutaneous needle placement in a pig model.
