Acute: Subtle low signal (hypointense) on T1, often difficult to see at this stage, and high signal (hyperintense) on spin density and/or T2-weighted and proton density-weighted images starting 8 h after onset; should follow vascular distribution. Mass effect maximal at 24 h, sometimes starting 2 h after onset, even in the absence of parenchymal signal changes. No parenchymal enhancement with paramagnetic contrast agent. Territorial intravascular paramagnetic contrast enhancement of “slow-flow” arteries in hyperacute infarcts; at 48 h, parenchymal and meningeal enhancement can be expected.

Computed tomography (CT) is widely used for early evaluation of acute strokes. Most importantly, CT excludes acute hemorrhage or other diseases mimicking ischemia. Continue reading “Diagnostic Criteria of Infarction in CT Imaging of the Brain in Acute Stroke”
The diagnostic criteria for tuberous sclerosis complex (TSC) were revised at the Tuberous Sclerosis Complex Consensus Conference, July 1998.
Definite TSC: Two major features or one major feature plus two minor features
Probable TSC: One major feature plus one minor feature
Possible TSC: One major feature or two or more minor features
