Can you imagine being treated
for a high fever, racking cough
and pneumonia without a chest
x-ray?
It has taken 34 years, many scientists and
clinicians worldwide to develop prostate
MRI for clinical use. Prostate MRI was
introduced into the North American
healthcare system only few years ago.
Can you imagine being diagnosed
or treated for
prostate cancer without your
doctor being able to see it?
The current practice of PSA Screening
Trans Rectal Ultrasound (TRUS) schematic
biopsy is inaccurate and misses one third
of the
prostate cancers that
cause serious illness and frequently
diagnoses non-aggressive cancers which
cause no harm.
That is what we were doing!

TRUS/MRI fusion targeted biopsy usually
diagnoses the aggressive cancers at the
initial biopsy session avoiding repeat
biopsy sessions and biopsy complications.
When aggressive prostate cancers are
diagnosed Prostate MRI becomes key in
treatment selection and planning.

The MRI Exam
Prostate MRI takes 40-50 minutes.
The MRI unit may surround you to
your chin, vibrates and is noisy.
A small injection of Buscopan and
Gadolinium are given. Buscopan can
cause a dry mouth and difficulty
voiding after the exam. A cold
sensation may occur with the
Gadolinium injection. Patients with
poor kidney function can not have
Gadolinium.
MRI examines the prostate in
3 different detailed parameters –
external and internal anatomy,
cell density and micro blood
vessels. Imaged are all the pelvic
organs – prostate, bowel, bladder,
bones, large blood vessels and
lymph nodes.
You may not be able to have a
prostate MRI if you have moving

body
parts
or
are
claustrophobic.
Prostate MRI
A Major Advancement
o Evaluates men at risk of prostate cancer
o Locates and characterizes cancer nodules
o Selects/limits the number of men requiring
biopsy
o Precision TRUS/MRI fusion targeted biopsy

Accuracy
Prostate MRI is 90% accurate in
diagnosing aggressive prostate cancer
when the MRI exam is of high quality,
the report clinically useful, experienced
radiologist, MRI knowledgeable
urologist and a pathologist to
provide proof of the presence of cancer
from tissue samples.
