“…Our study demonstrates that the technical success rate of PNB under this CBCT virtual navigation system was 100.0%, which corresponds to the rate reported by Tselikas et al,12 who investigated bone biopsy under CT and CBCT (both 100%). In our study, sufficient tissue for histopathological analysis was obtained in 93.7% of lesions.…”

ObjectivesTo assess the clinical role of flat-panel cone beam CT (CBCT) in performing percutaneous needle biopsy (PNB) of bone lesions. Flat-panel cone beam CT systems have been used as a guidance tool for performing percutaneous biopsy. Real-time fluoroscopy and virtual navigation systems help simplify needle path planning and shorten procedure times.MethodsFrom March 2012 to March 2016, 80 patients with 80 bone lesions were retrospectively enrolled in the study in Zhengzhou city of China. Technical success, diagnostic accuracy, puncture performance, procedure time, complications, and effective radiation exposure were calculated.ResultsAll biopsies were technically successful (100%). Sufficient tissue for histopathological analysis was obtained in 75 of 80 cases. The sensitivity of PNB of bone lesions was 95.5%, the specificity was 83.3%, and accuracy was 93.7%. The mean scoring of puncture performance was 3.9 ± 1.3. The mean total procedure time was 13.20 ± 4.4 min, resulting in a mean exposure dose of 11.3 ± 5.1 mSv. The complication rate was 8.7%.ConclusionPercutaneous bone biopsy using CBCT is a safe and effective method that simplifies needle path planning and shortens procedure times.

“…This finding was in accordance with data reported in clinical literature [10,19], although we would have expected much lower values for CACT. We believe that these results are caused by the higher number of CACT acquisitions in some patients.…”

Ziel: Evaluation der Durchführbarkeit und Effizienz der Kombination aus C-Arm Flachdetektor-CT (FD-CT) und elektromagnetischer Navigation (EMN) bei der Steuerung perkutaner Nadelbiopsien. Abstract !Purpose: To evaluate the feasibility and efficacy of C-arm fluoroscopic cone-beam computed tomography (CACT) in combination with a new electromagnetic tracking (EMT) system for needle guidance during percutaneous biopsies. Materials and Methods: 53 patients were referred for biopsy of thoracic (n = 19) and abdominal (n = 34) lesions. CT-like images of the anatomical region of interest (ROI) were generated using a flat panel-based angiographic system. These images were transmitted to an EMT system. A coaxial puncture needle with a sensor in its tip was connected with the navigation system and tracked into an electromagnetic field created via a field generator. Data generated within this field were merged with the CACT images. On a monitor both the anatomical ROI and needle tip position were displayed to enable precise needle insertion into the target. Through the coaxial needle, biopsy specimens for the histologic evaluation were extracted. Number of representative biopsy samples, number of core biopsies/patient, total procedure time, dose-area product, fluoroscopic time, and complications were recorded. Results: 53 CACT/EMT-guided biopsy procedures were performed, 48 of which (91 %) yielded representative tissue samples. Four core biopsies were obtained from each patient. 40 (75 %) lesions were malignant and 13 (25 %) lesions were benign. The total procedure time was 9 ± 5 min (range, 3 -23 min), fluoroscopic time was 0.8 ± 0.4 min (range, 0.4 -2 min). The mean dosearea product (cGy cm²) was 7373 (range, 895 -26 904). The rate of complications (1 pneumothorax, 2 hemoptyses) was 6 %. Conclusion: CACT combined with EMT appears to be a feasible and effective technique for the guidance of percutaneous biopsies with a low rate of therapeutically relevant complications.This document was downloaded for personal use only.

“…The radiation dose is naturally higher than with standard fluoroscopy. However, compared with complex punctures with standard multidetector computed tomography (MDCT), the radiation dose even might be lower in cone-beam CT-guided procedures as with the Uro Dyna-CT [13][14][15].…”
