Purpose: Gold seed fiducial markers can be used to accurately define daily treatment field placement for prostate cancer patients. In 2007, a small study was undertaken to evaluate the effectiveness of using gold seed fiducial markers. Methods: Eleven patients who attended for treatment had three ...
in more recent years EUS placement via an FNA needle has been preferred as a less invasive method for fiducial marker placement in GI malignancies, including esophageal tumors, cholangiogiocarcinomas, gastric cancers, and malignant lymph nodes.161–163In esophageal cancer, where there is a malignan...
Electromagnetic Navigational Bronchoscopy: A Safe and Effective Method for Fiducial Marker Placement in Lung Cancer Patients. The emergence of Electromagnetic Navigational Bronchoscopy (ENB) as a diagnostic tool for small peripheral lung nodules has introduced a new method for del... D William,Bolton,Jo...
The rate of using 2 fiducial markers for tracking during the treatment was 22.20% and 9.38% of the markers were not used.We must keep improving the quality of fuducial marker implantation and the number of markers.We should lower the rate of using two markers as much as possible and raise...

In this technical development report, we present the strategic placement of fiducial markers within the prostate under the guidance of computed tomography (CT) and electromagnetic navigation (EMN) for the delivery of ultra-hypofractionated cyberknife (CK) therapy in a patient with localized prostate ca...

When using FM as a surrogate for the vagina position, the stability of the markers during RT and marker placement is essential. In only 2/18 patients a FM was lost during or prior to treatment. In the previously mentioned studies this was the case in 3/25 and 4/11patients [12], [15...
