“…The high levels of diagnostic accuracy with and without CTF are comparable to those of previous reports, ranging from 81% to 94% [9,[21][22][23][24][25][26]. We were unable to document significantly improved diagnostic accuracy using CTF in this study.…”

“…Contrary to US or fluoroscopy, conventional CT-guided procedures are limited by the lack of real-time capability, and the imaging steps required to monitor and document needle placement are often timeconsuming. Compared with conventional CT-guidance, CTF is faster and requires fewer needle passes than conventional CT-guided techniques [5,6,[8][9][10]. CTF provides an excellent real-time view of the procedure.…”

“…Therefore, CT fluoroscopy guidance decreases procedure time and requires fewer needle passes than CTguided procedures without fluoroscopy [5,6,[8][9][10]. Clinical studies have shown that CT fluoroscopy is a safe and effective tool to guide percutaneous intervention procedures in the chest, spine, abdomen, and pelvis [7,[10][11][12].…”

“…CTF provides real-time guidance of the biopsy needle, decreases procedure time and requires fewer needle passes than CT-guided procedures without fluoroscopic guidance [2][3][4][5][6]. CTF has furthermore been shown to significantly reduce radiation doses to the patients, but it exposes the radiologist to radiation, as the operator is in the room at the time [7,8].…”

The aim of this study was to determine the diagnostic accuracy and frequency of complications of lung biopsy procedures with or without CTF guidance of needle insertion. Records and images of 99 consecutive percutaneous coaxial cutting needle lung biopsy procedures performed on 85 patients were reviewed retrospectively. Fifty-seven and 42 procedures had been done with and without CTF guidance, respectively. Histological results were compared to diagnosis after surgery or after a follow-up period of 12 months. Diagnostic accuracy and the occurrence of pneumothorax and/or bleeding related to the procedures were registered. The level of accuracy of the diagnosis was comparable. The diagnostic accuracy was 96% (50/52) and 95% (34/36) sensitivity 95% (35/37) and 93% (26/28), specificity 100% (15/15) and 100% (8/8) with CTF and conventional CT techniques, respectively. There were fewer post procedure pneumothoraces using the CTF than conventional technique [26% (15/57) vs. 38% (16/42)], but the difference was not statistically significant (P = 0.274). The insertion of a chest tube was required in only one (2%) procedure using the CTF technique, while this was needed in four (10%) using the conventional technique. Small or large hemorrhages occurred in 23% of the procedures, with no apparent difference between the two groups. In conclusion, CTF-guided biopsy of lung lesions provides high diagnostic accuracy, comparable to that of conventional CT-guided procedures, with a low rate of complications, even for small tumors.

“…Definitely, CT has been proven to be an effective guidance technique for obtaining diagnostic specimens especially in anatomical regions which are considered inaccessible when utilizing alternative guidance modalities such as conventional fluoroscopy or ultrasonography [7,13,14]. Some investigators who examined the usefulness of CT coupled with magnetic guidance inferred that this combination might be beneficial in terms of accuracy and safety, especially in out-of-plane biopsy approaches [22].…”

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.
