Conclusion: The Gold Anchors implantation is small invasive and safe method. The risk of side effects appearance is low. English, translation from Polish articlePolish original
Conclusion: The patient positioning using 2D/2D kV and Gold Anchors increases the setup precision and enables to reduce margins. Because the prostate motion during the course of radiotherapy can be significant, margins for the PTV should include the intrafraction prostate mobility. Poster at ESTRO 2010, poster #1674
Conclusion: The position of the Gold Anchor™ fiducial marker in the prostate gland is stable, the marker remaining within the gland volume. The period of marker stabilization is less than the 7 days recommended by the manufacturer. We suggest that virtual simulation of the patient can be performed immediately after marker implantation.

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 […]
Abstract: In 621 consecutive prostate cancer patients, the frequency of urinary tract infections (UTI) and marker loss was evaluated. They prophylactically received a single dose of non-broad-spectrum antibiotics and transrectal implantation of three thin needle fiducial markers, Gold Anchor ™ (GA). The occurrence of UTIs, sepsis, hospitalization due to infection, and marker loss after implantation […]
Purpose: Triggered imaging is the use of kV image acquisition during treatment delivery to monitor intrafractional motion of implanted fiducials. An automatically identified fiducial point on the kV image is compared to its expected position predetermined from the treatment planning CT, and the treatment can be paused if the difference exceeds a user-definable tolerance. Conclusion: Triggered […]
Summary: Between 2015 and 2017, 96 patients had 3 Gold Anchor fiducial markers placed in conjunction with transperineal SpaceOar placement into the prostate at the University of Florida Health Proton Therapy Institute (UFPTI). None of these patients developed sepsis. The authors write in their discussion “Bacterial UTI following fiducial placement to facilitate treatment planning and […]
Background: Fiducial markers are frequently used before treatment for imageguided patient setup in radiation therapy (RT), but can also be used during treatment for image‐guided intrafraction motion detection. This report describes our implementation of automatic marker detection with periodic kV imaging (TrueBeam v2.5) to monitor and correct intrafraction motion during prostate RT. Methods: We evaluated […]
Summary: The effect on diffusion-weighted (DWI) MRI was evaluated of 0.28×10 mm Gold Anchor fiducial markers, implanted with a line shape. Conclusions: Gold fiducial markers demonstrated negligible effect on DWI quality. Therefore, it appears that the use of these markers does not preclude the optimal utilization of MRI, particularly DWI, during follow-up in prostate cancer […]
