Facets:
Source sentences:
text: non-contrast CT hyperdense basilar artery (the basilar artery equivalent of the hyperdense MCA sign), present in ~65% 9 a high index of suspicion is needed in the correct clinical setting as the diagnosis can easily be missed (often only present on 1 or 2 slices); additionally it is well recognized that acute clots are of lower attenuation than chronic clots 5-6 hypoattenuation delineates tissue with ischemic damage (limitations due beam-hardening artifacts limit the visualization of the brainstem on CT)
