Efficacy and safety of ultrasound-guided implantation of fiducial markers in the liver for stereotactic body radiation therapy. [PDF]

PLoS ONE, 2017
Stereotactic body radiation therapy (SBRT) for the treatment of a malignancy in the liver requires the perilesional implantation of fiducial markers for lesion detection. The purpose of this study is to evaluate the efficacy and safety of ultrasound (US)

Intracardiac Migration Following Percutaneous Computed Tomography-Guided Fiducial Marker Implantation for Pulmonary Metastasis: A Rare Complication

The Arab Journal of Interventional Radiology, 2020
A 41-year-old female with rectal cancer and lung metastasis underwent percutaneous transthoracic placement of fiducial marker. Postprocedure scan showed the migration of one of the fiducial markers to the left ventricle.

Planar fiducial markers: a comparative study

Virtual Reality, 2023
Fiducial markers are a cost-effective solution for solving labeling and monocular localization problems, making them valuable tools for Augmented Reality (AR), robot navigation, and 3D modeling applications. However, with the development of many marker detection systems in the last decade, it has become challenging for new users to determine which is ...

Computed tomography based evaluation of prostatic fiducial marker migration between the periods of insertion and simulation

Urology Research and Practice, 2019
Objective: The aim of this study was to determine whether significant fiducial marker migration occurs between the periods of prostatic marker insertion and computed tomography (CT) performed for radiotherapy planning and if a waiting period is necessary.
