So this next patient, case number three, is a 73 year old with
0:05
memory loss. They had an MRI of the brain in 2016.
0:09
First, look at the DWI, there's no evidence of acute infarct, though we
0:13
actually don't have a GRE sequence or a FLAIR sequence on this case
0:17
because the patient was not able to tolerate finishing their MRI,
0:21
but we do have a T2. And on that, we see that there's moderate
0:25
to moderately severe cerebral atrophy with a right mesiotemporal predilection.
0:29
We see the prominence and size here of the right temporal horn, and
0:33
this is what the rest of the brain looks like. If you look
0:36
here on the coronal images, these are the hippocampi, and we see the hippocampal
0:40
atrophy bilaterally, particularly on the right hand side.
0:44
There is moderate microvascular ischemic disease that we see here, T2 hyperintensity
0:49
in the cerebral white matter. The patient also had an amyloid study in
0:53
2016, and this is diffusely positive. So you see diffuse binding of the
0:58
amyloid tracer throughout the cortex. The entire brain looks dark on amyloid.
1:02
This is an evidently positive exam, which tells us that this patient does
1:07
indeed have Alzheimer's. Okay, so case number three again is the 73 year
1:13
old with memory loss. Here is the MRI in 2016, moderate to moderately severe
1:18
atrophy with a right temporal predilection. The patient had quantitative
1:22
volumetric imaging in 2016. There was some reduction in hippocampal volumes,
1:26
but of note, there was statistically significant reduction in the HOC
1:31
for the patient here. The icobrain also showed reduction of the
1:35
hippocampal volumes and enlargement of the inferior lateral ventricles.
1:39
You see here in this report that it's
1:41
up here in the pink zone, indicating that the inferior lateral ventricles
1:46
are significantly enlarged. This patient then had an amyloid PET in 2016.
1:52
Here's the PET CT fusion images. Here's the PET MR fusion images.
1:57
This is diffusely positive, so binding of that amyloid tracer throughout
2:01
the cortex in this patient who has Alzheimer's disease.
