Contrast extravasation on CT predicts mortality in primary intracerebral hemorrhage.
Recent studies of intracerebral hemorrhage (ICH) treatments have highlighted the need to identify reliable predictors of hematoma expansion. The goal of this study was to determine whether contrast extravasation on multisection CT angiography (CTA) and/or contrast-enhanced CT (CECT) of the brain is associated with hematoma expansion and increased mortality in patients with primary ICH. ⋯ Active contrast extravasation on CT in patients with primary ICH independently predicts mortality and hematoma growth.

Identification of the normal jugular foramen and lower cranial nerve anatomy: contrast-enhanced 3D fast imaging employing steady-state acquisition MR imaging.
Conventional imaging protocols are unable to visualize the intraforaminal/canalicular segments of the lower cranial nerves (IX-XII). On the basis of previous successful demonstration of individual cranial nerves within the cavernous sinus by constructive interference in steady-state MR imaging, we describe the use of contrast-enhanced 3D fast imaging employing steady-state acquisition MR imaging to demonstrate normal in vivo intraforaminal and canalicular segments of cranial nerves IX-XII in 10 patients by using a standardized imaging protocol.
