Conclusion: The new MRI compatible Gold Anchor™ adds new features on top of the existing advantages. For specific anatomical targets treatment planning with fiducial marker information can be performed based only on MR images. For other targets images from both MRI and CT can be matched through the information from the fiducials. The content of […]

Abstract: Visualization of markers is critical for imaging modalities such as computed tomography (CT) and magnetic resonance imaging (MRI). However, the size of the marker varies according to the imaging technique. While a large-sized marker is more useful for visualization in MRI, it results in artifacts on CT and causes substantial pain on administration. In […]
Summary: Gold Anchors were implanted through 22-gauge needle in two liver cancer patients at the Gifu Municipal Hospital in Japan. This caused little pain during placement under local anesthesia with xylocaine. No complication occurred in either patient. The iron-containing fiducial marker composed of 99.5% gold and 0.5% iron made visualization in MRI easy, which helped […]
“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): […]
