Pulsed Reduced Dose Rate Radiotherapy- (PRDR)

This handout tells you what PRDR is and
what will happen during treatment. When
reading this handout, mark any area you do
not understand. Make a list of questions you
may have. Your therapist or doctor can
discuss those with you.

What is PRDR?
PRDR is a way of giving small pulses of
radiation at a reduced dose rate over a longer
period of time. Since the radiation is given
rapidly, daily treatments require only minutes
to deliver. This method may be used on areas
that were treated before.

What happens during a treatment visit?
Arrive to the treatment area at your scheduled
time. Be sure to check in with the staff when
you arrive.
ξ A therapist will call you into the room to
explain the process in detail.
ξ You may need to remove some clothing or
personal items. It will depend on the site
being treated.
ξ We will position you on the treatment
table. The therapist(s) may need to move
you to get the correct position.
ξ We will take x-rays (pictures) to check
your position. Your doctor approves the
x-rays, and then treatment begins.
Treatment lasts about 45-60 minutes
depending on the area treated.
ξ You will hear buzzing noises during
treatment. This is from the machine. You
will hear this until the prescribed dose of
radiation has been delivered.
ξ After treatment, the therapist(s) will come
in the room and help you off the table.
ξ The therapist(s) can see and hear you at
all times during your treatment. If you
need anything, wave your hand or call out.
They will stop the machine and help you
right away.
ξ Side effects of treatment depend on what
part of the body is being treated. Your
doctor will discuss these with you.
ξ For questions or problems once you are
home, call the Radiation Oncology Clinic
at 608-263-8500 or the treatment unit
directly. They will provide you with the
treatment unit phone number. If the clinic
is closed, call the main clinic number at
608-263-8500. The hospital paging
operator will answer. Ask to speak to the
Radiation Oncology doctor on call. Give
your name and phone number with area
code. The doctor will call you back.
