Proximal lesion
an acute bleed on ct appears hyperdense, hence the use of ct when a head bleed is suspected.

Traumatic lesions to the brain are well seen without i.v. contrast agents. In particular, traumatic hemorrhage, be it epidural, subdural, subarachnoid, parenchymal or intraventricular, is spontaneously hyperdense on CT. Theoretically, i.v. contrast would be, at best useless, at worst counterproductive.
