Detection, characterization and functional assessment of reperfused Q-wave acute myocardial infarction by cine magnetic resonance imaging

Consequences of Circadian Disruption on Neurologic Health

“…7 While stroke exhibit this clustering in the morning, some studies reported a bimodal distribution of stroke onset in hemorrhagic strokes with the second peak being in the afternoon. 8–12 The effects of the recombinant tissue plasminogen activator rt_PA treatment on outcomes have been independent of time of day stroke onset. 13 Majority of investigations related to 24h patterns in stroke are centered on the “time of day” when stroke occurred, lacking relevant determinants of exogenous influences such as the rest/activity rhythm and other known risk factors.…”

Interobserver Variability in Assessing Segmental Function can be Reduced by Combining Visual Analysis of CMR Cine Sequences with Corresponding Parametric Images of Myocardial Contraction

“…As CMR has the advantage to be a native matricial acquisition allowing to study wall thickening without geometrical assumptions most early studies in CMR relied on wall motion and thickening analysis (9)(10)(11)). Yet, this approach is impaired by high regional thickening variability and still requires contour tracing thus leaving cine loop reading to be considered the practical reference standard for the evaluation of SC.…”

Quantitative analysis of regional left ventricular function after myocardial infarction in the pig assessed with cine magnetic resonance imaging

“…The gradient echo (cine) MR imaging technique has been used to evaluate global and regional LV function. However, most studies relied on visual assessment of wall motion and wall thickening (12, [14][15][16], which precludes measurement of large numbers of data points and suffers from observer bias. To date, the number of measurements used for regional LV wall function analysis is limited by the lack of sophisticated analysis software.…”
