Now, we conduct cerebral microbleeds (CMBs) assessment.
First, we open the VVEN_BOLD SWI sequence.
This patient has 2 CMBs, and we can observe them first.
CMBs are punctuate or small round/oval hypointense foci of 2-10 mm diameter.
the BOMBS scale was used to get good interrater agreement.
The whole brain was divided into 7 anatomical locations.
The assessment should also be conducted separately for both hemispheres.
Scan the entire brain in a specific order, looking for suspicious lesions.
We see a suspicious lesion,
mark it.
A new lesion, a new mark.
Layers with marks will be indexed in the top navigation bar, so it is easy to backtrack.
This ruler tool is for measurement of lenth, like diameter.
Here is one of the tips for identifying mimics.
Place the lesion in the center of the cursor, scrolling the layers,
and the lesion always stops at the center of the cursor.
The same is true of this lesion.
Two suspected lesions here. The position is changing across layers.
They also point to vessels nearby. So, they're considered the vascular cut.
Here is a diagram. The cerebellum and the brain stem were not shown.
