In transient MCAO models, T2 relaxation time values and lesion sizes based on T2 changes have been shown to correlate to somatosensory test scores at different time points (Palmer et al. 2001 Virley et al. 2000). This bears great clinical relevance, because the alleviation of a patient s functional deficits is the primary motivation of experimental stroke studies. However, reliable prediction of functional impairment by MRI is not undisputed. We noted positive striatal T2-w MRI findings in the absence of functional deficits and concluded dissociation between these two diagnostic variables in certain stroke patterns (Wegener et al. 2005).

In patients with high-grade stenosis the highest frequency of lesions occurs in the hemodynamic risk zones...

Brain scans are used to study epiiepsy, brain tumors, strokes, Aizheimer s disease, and mentai iiiness. Each of these disorders generates a unique brain activity pattern that differs from the pattern seen in normai brains. Physicians interpret these patterns both for diagnosis and to indicate appropriate treatment. 

OR 1.81, 95% Cl 1.46-2.24), most of which were related to symptomatic intracranial hemorrhage (OR 3.37, 95% Cl 2.68. 22). In addition, a pooled analysis of six major randomized placebo-controlled IV rt-PA stroke trials (Alteplase Thrombolysis for Acute Noninterventional Therapy in Ischemic Stroke (ATLANTIS) I and II, European Cooperative Acute Stroke Study (ECASS) I and II, and NINDS I and II), including 2775 patients who were treated with IV rt-PA or placebo within 360 minutes of stroke onset, confirmed the beneht up to 3 hours and suggested a potential beneht beyond 3 hours for some patients. The pattern of a decreasing chance of a favorable 3-month outcome as the time interval from stroke onset to start of treatment increased was consistent with the findings of the original NINDS study. ...

Cardioembolism Cardioembolism accounts for approximately 30% of all stroke and 25-30% of strokes in the young (age <45 years)." AF accounts for a large proportion of these strokes (15-25%). Symptoms may be suggestive, but they are not diagnostic. Repetitive, stereotyped, transient ischemic attacks (TIAs) are unusual in embolic stroke. The classic presentation for cardioembolism is the sudden onset of maximal symptoms. The size of the embolic material determines, in part, the course of the embolic material. Small emboli can cause retinal ischemic or lacunar symptoms. Posterior cerebral artery territory infarcts, in particular, are often due to cardiac embolism. This predilection is not completely consistent across the various cardiac structural abnormalities that predispose to stroke, and may be due to patterns of blood flow associated with specific cardiac pathologies.

A four-stroke internal combustion engine was built by a German engineer, Nicholas Otto, in 1876. The cycle patterned after his design is called the Otto cycle. It is the most widely used internal combustion heat engine in automobiles.
