So why MRI?
0:02
We've discussed in prior vignettes,
0:05
surveillance is one of the primary
0:07
indications for MRI, especially in
0:09
individuals with the lower tier of disease,
0:13
which is again divided up into three tiers.
0:16
So let's talk about what those three tiers are.
0:20
You can break it down into three basic
0:24
categories that determine whether you're
0:27
in tier one, tier two, or tier three.
0:29
So let's start with tier one.
0:32
In tier one, And I'll put the number 1 up here.
0:36
The PSA is going to be 10 nanograms per mL,
0:42
which should be an N, nanograms per mL or
0:45
less, or 10 micrograms per liter or less.
0:50
The Gleason score should be 6 or less.
0:55
The clinical T category is
0:57
going to be T1C and T2A.
1:01
You don't know what those are?
1:03
That's what Google is for.
1:05
All right.
1:06
Let's look at tier number 2.
1:09
Let's get my, actually I'll leave
1:11
everything on here and we'll go to tier 2.
1:13
We'll use a different color.
1:14
Let's use blue.
1:17
Alright, so tier number 2.
1:20
The PSA level is going to be between 10 and 20.
1:26
Not going to repeat the units,
1:27
just to save you some time.
1:29
The Gleason score is 7.
1:32
And the T category is going to be T2B.
1:39
T2B, by the way, does not qualify for high risk.
1:43
Let's go to tier number three.
1:46
Tier number three, let's
1:47
pick a color that we like.
1:49
Oh, let's go with bright green.
1:51
Tier three.
1:53
The PSA level is greater than 20
1:57
nanograms per mL, or micrograms per liter.
2:00
The Gleason score is 8 to 10,
2:04
as you might have expected.
2:06
And the clinical T category is T1.
2:13
So, it's this red group, tier number one,
2:17
and perhaps a small subset of tier number
2:20
twos that are candidates for MR surveillance
2:23
with either a diagnostic MRI or, as we'll
2:27
see, a screening MRI which takes less than 15
2:30
minutes and is equally accurate in detecting
2:33
aggressive cancer as a diagnostic MRI.
2:37
We'll have a look at those later.
2:39
Thanks.
