- Abstract
Purpose: To evaluate a new adjunctive guidance device, a puncture guide, constructed to simplify computed tomography (CT)‐guided punctures and to make the procedure more accurate and safe. Material and Methods: 17 patients referred for CT‐guided punctures were included in the study. There were 10 thoracic and 7 abdominal or pelvic lesions with a mean maximum diameter of 29±18 mm. All punctures were performed using a laser guide combined with the new device. The needle guide created a streak artefact in the image, indicating the needle path. Results: The puncture was successful at the first attempt in 15 of the 17 patients. The artefact was visible in all patients, and in the majority there was a distinct artefact reaching from the entry point to the lesion. The deviation between the angle of the streak artefact and the final angle of the needle was 1.1°. Conclusion: The benefits of the puncture guide were the artefact pointing at the target, the needle support, and accuracy when performing CT‐guided punctures.
