Subdural hematoma acute status
Status of a collection of acute blood between the arachnoid and the dura, typically (though not always) hyperdense with a crescent shape on CT. Mixed density may be seen if the collection contains unclotted blood, CSF admixture, and/or active extravasation. On MRI, the acute SDH is iso/hypointense on T1 and very hypointense on T2, GRE, and SW-imaging. Note: Please see additional categories below for subacute, chronic, and mixed collections if these better describe the lesion, or if the chronicity/timing is uncertain
