Findings
| MR susceptibility (SWI) | Correct Answer | Your Answer |
|---|---|---|
|
There is evidence (positive susceptibility artifact) of acute or prior subarachnoid blood. |
Yes | NA |
|
There is evidence (positive susceptibility artifact) of acute or prior intraaxial hemorrhage. |
Yes | NA |
|
There is evidence (positive susceptibility artifact) of acute or prior intraventricular blood. |
Yes | NA |
|
There is evidence (positive susceptibility artifact) of acute subpial blood. |
No | NA |
|
There is evidence of multicentric sites of parenchymal hemosiderin consistent with: chronic hypertensive encephalopathy, cavernous angiomata, amyloid angiopathy, or prior radiotherapy. |
No | NA |
|
There is "blooming susceptibility artifact" over arteries consistent with recent thrombosis. |
No | NA |
|
There is "blooming susceptibility artifact" over cortical or deep veins consistent with recent thrombosis. |
No | NA |
|
There are multicentric sites of pial surface microhemorrhages (result of mainly diapedesis rather than overt hemorrhage); evident in herpes simplex encephalitis, microhemorrhage in hypo-coagulopathy states. |
Yes | NA |
|
Other significant imaging findings are present. |
No | NA |
Impression
Expert Answer
Late subacute and chronic subarachnoid blood products show progressively more blooming effects. Acute subarachnoid blood is evident SWI, but the degree of blooming is minimal.
