Exam
Purpose
2 Assess for positive diffusion in one or more pial, deep central, or deep medullary veins.
3 Assess for positive diffusion in any cortical ribbon (laminar necrosis).
4 Assess for positive diffusion in any site subcortical penetrating arterial site.
5 Assess for single or multicentric small sites consistent with ischemia in terminal arteries.
6 Assess whether there is post ischemic diffusion positivity in a recognizable as a watershed zone (confluent abnormal signal).
7 Assess whether there is a single or multicentric nonconfluent sites of post ischemic diffusion positivity in a recognizable terminal artery zone.
8 Evaluate the diffusion Bo sequence for hemorrhagic conversion.

Findings
MR Diffusion
There is acute, positive diffusion consistent with acute ischemia in a recognizable arterial perfusion zone in a major stem, trunk, division or pial artery perfusion zone. [Yes/No]
There is acute, positive diffusion consistent with acute ischemia in a recognizable perforator, choroidal, or deep subcortical penetrating artery/arteries. [Yes/No]
There is acute, positive diffusion consistent with acute ischemia in recognizable centronuclear structures or brainstem perforator zone. [Yes/No]
There is acute positive diffusion consistent with acute ischemia in a recognizable watershed zone. [Yes/No]
There is acute, positive diffusion consistent with acute ischemia in a recognizable venous egress zone. [Yes/No]
There is acute, positive diffusion consistent with acute ischemia within the cortical ribbon consistent with sequestered infarction (laminar necrosis). [Yes/No]
There is acute positive diffusion in parenchyma that does not clearly fit into either a recognizable arterial or venous territory, but fits better with terminal artery oligemia and transcapillary ischemic changes. [Yes/No]
There is acute, abnormal diffusion within one or both hippocampi indicating a recent seizure event. [Yes/No]
There is evidence of intercurrent reperfusion hemorrhage. [Yes/No]
Other
No other abnormalities are noted. [Yes/No]
