Patient instructions for preparing for placement of fiducial markers to be used for Radiation Therapy.
A fiducial marker is a small gold seed about the size of a grain of rice (0.8mm to 5mm).
It is useful in helping focus, or target, the radiation therapy to the area most needed while sparing surrounding tissue.
It is placed by an interventional radiologist guided by imaging (CT, Ultrasound or MRI).
This is done at Fox Chase Cancer Center in the Diagnostic Imaging department, 1st floor of the hospital.
It may take up to an hour to perform. You may require light sedation so please have someone accompany you for this procedure.
Your nurse will arrange the date and time for placement of the fiducial markers.
You will need lab work done within 2 weeks of the procedure.
CBC, PT/PTT, Bun and Creatinine with GFR. These can be done at your local lab or doctor’s office within the noted timeframe of 2 weeks. We can provide you a lab slip to have these drawn so they can be faxed to us. They can also be done the morning of the procedure at Fox Chase.
