Prostate MRI (Magnetic Resonance Imaging).
0:02
It's new.
0:04
It's hip.
0:05
It's happening.
0:06
It's relevant.
0:07
Let's get ready to rumble, because this is the
0:09
second leading cause of male cancer death in
0:13
MR now, and is going to have an even bigger
0:16
impact on the management of this disease.
0:20
There are a quarter of a million cases in the U.S.
0:22
0:22
alone, and there are 161,360 new patients each year.
0:30
There are 26,730 deaths in 2017 from prostate
0:37
cancer, according to the American Cancer Society.
0:41
So it's no wonder that we are looking for
0:44
better methods of diagnosis and treatment.
0:49
Initially, we diagnosed prostate cancer with
0:52
some relatively rudimentary techniques, like your
0:56
finger, the digital rectal exam, which nobody
1:01
including myself, likes getting when they go
1:04
to see their internist for their yearly exam.
1:07
In addition, it's not a very sensitive
1:10
or specific screening technique.
1:13
That's also true for self-breast examination.
1:16
The serum PSA, or prostate-specific antigen.
1:22
We know that the normal prostate makes PSA.
1:26
So if your prostate gets bigger, as in
1:30
hyperplasia, as in benign hyperplasia, The
1:33
more prostate you have, the more PSA you make.
1:37
So the PSA elevation in
1:39
itself is not a reliable sign.
1:42
In most instances, that you have prostate cancer.
1:47
So, we hope to share with you, over the
1:50
next several hours, in mini-vignettes,
1:53
snippets, that you can look at very briefly,
1:55
what we are capable of, without entering
1:59
somebody's rear end with an endorectal coil.
2:02
In other words, you don't need an endorectal
2:04
coil to do proper diagnostic and screening
2:08
prostate MRI, nor do you need a 3 Tesla magnet.
2:14
This is an indirect coil showing you the
2:17
prostate gland in all its glory in a 7-year-old 1.
2:20
5 Tesla machine.
2:22
But you don't even need a new machine.
2:25
You need some very basic techniques to
2:30
diagnose and screen prostate cancer and
2:32
they include high-quality T2 spin echo
2:35
imaging with good external coil technology
2:39
and high-quality diffusion imaging.
2:41
If you have that, you can do prostate MR.
2:45
Let's move on, shall we?
