Conclusion: It is feasible to use gold anchor marker for Cyberknife. Ball shape or Tadpole gold anchor markers are recommended. Visual confirmation of lock-on is important due to the irregular shape of gold anchor markers. More study is needed to evaluate clinical effect.

Conclusion: We describe the use of the Gold Anchor fiducial markers in this poster. They have the advantage that a small amount of ferromagnetic material is mixed in the gold alloy to allow better visibility on MRI imaging than gold alloy fiducials alone. There are other markers that have been described (ref. 1) that also […]
Summary: This is the largest series reporting the feasibility and complications of the use of the Gold Anchor 25G system for percutaneous puncture in the lung. This is a quick procedure, performed under local anesthesia. A single marker per lesion minimizes the risk of complications related to the implementation: with a pneumothorax rate of 25% […]
Summary: In Italy, ultrasound guided implantation in liver was performed in 50 patients of 68 gold grain markers 1×4 mm through 17-gauge needles, 78 Gold Anchors 0.4×10 mm through 22-gauge needles, and 17 Gold Anchors 0.28×10 mm through 25-gauge needles. The use of 17-gauge needles resulted in five patients developing abdominal pain and the migration […]
Summary: Gold Anchors were implanted percutaneously via the trans-thoracic route in lung in 80 patients for CyberKnife treatments at the Hartmann Radiotherapy Institute in France. This led to 9 cases (11%) of pneumothorax, out of which 2 cases (2.5%) required a drain. All implanted fiducials were effectively tracked by CyberKnife. Article in Radiation Oncology, 2019
“Evaluation of computed tomography metal artifact and CyberKnife fiducial recognition for novel size fiducial markers” Purpose: This study aimed to compare fiducial markers used in CyberKnife treatment in terms of metal artifact intensity observed in CT images and fiducial recognition in the CyberKnife system affected by patient body thickness and type of marker. Methods (extract): […]
