Pearls & oy-sters: hyperdense or pseudohyperdense MCA sign: a Damocles sword?
• The presence of a true hyperdense sign can be confirmed by measuring attenuation value as compared to the normal-appearing contralateral side. • Mimics of a hyperdense sign (i.e., a pseudohyperdense sign) include vascular calcification, raised hematocrit, and intravenous contrast medium. • Careful attention should also be paid to the surrounding brain parenchyma to assess for hypodensity or a...

متن کاملOn strongly dense submodules
The submodules with the property of the title ( a submodule $N$ of an $R$-module $M$ is called strongly dense in $M$, denoted by $Nleq_{sd}M$, if for any index set $I$, $prod _{I}Nleq_{d}prod _{I}M$) are introduced and fully investigated. It is shown that for each submodule $N$ of $M$ there exists the smallest subset $D'subseteq M$ such that $N+D'$ is a strongly dense submodule of $M$ and $D'bi...
متن کاملDense middle cerebral artery sign: an indicator of poor outcome in middle cerebral artery area infarction.
Thirteen patients with a dense appearance of the horizontal part of the middle cerebral artery (MCA) "dense middle cerebral artery sign" in CT scans taken within 24 hours after onset of ischaemic stroke had considerably poorer prognosis than controls with stroke, but without the sign. A hyperdense appearance of the MCA is known to be associated with thromboembolism, but dense middle cerebral ar...
متن کاملPo-S-Dense Monomorphism
In this paper we take $mathcal A$ to be the category {bf Pos-S} of $S$-posets, for a posemigroup $S$, ${mathcal M}_{pd}$ to be the class of partially ordered sequantially-dense monomorphisms and study the categorical properties, such as limits and colimits, of this class. These properties are usually needed to study the homological notions, such as injectivity, of $S$-...
