BACKGROUND:Cardiovascular Magnetic Resonance (CMR) provides valuable information in patients with hypertrophic cardiomyopathy (HCM) based on myocardial tissue differentiation and the detection of small morphological details. CMR at 7.0T improves spat

Abstract Illegal bushmeat trade is a significant driver of the decline in wildlife populations within the tropics. Despite the intense trade of bushmeat in Cameroon, there is dearth or no official statistics on the kind of animals sold in the markets

The low survival rate of leverets may significantly contribute to steep population declines and slow recovery of European hares (Lepus europaeus). However, the leveret survival rate in farmlands with different landscape structures is poorly understoo

CMR at an ultra-high field (magnetic field strength B0 ≥ 7 Tesla) benefits from the signal-to-noise ratio (SNR) advantage inherent at higher magnetic field strengths and potentially provides improved signal contrast and spatial resolution. While pr
