Rapid magnetic resonance tissue relaxometry in the steady state [PDF]

, 2015
Longitudinal (T1) and transverse (T2) relaxation are the most fundamental physical processes governing the signal intensity and the soft tissue contrast in magnetic resonance imaging (MRI).

Peptide and drug interactions in murine models : in vitro and in vivo studies with microphysiometry, confocal microscopy and functional magnetic resonance imaging [PDF]

, 2004
The present thesis describes in three parts how living cells can be investigated on different biological levels, and how these techniques can be used to non-invasively evaluate the effect of drugs in the context of biomedical and pharmaceutical research.

Cerebellar activation associated with model-based estimation of tool-use consequences

Behavioral and Brain Functions, 2019
Background Dexterous tool use is considered to be underpinned by model-based control relying on acquired internal models of tools. In particular, this is the case in situations where available sensory feedback regarding the consequences of tool use is ...

Development of a deep learning algorithm for detection of liver cancers on Magnetic Resonance Imaging

, 2020
Early detection of liver cancer is crucial for improving patient management outcome. However, liver lesions can be differencaited to be identified. In recent years, the fully convolution neural network (FCNN) has shown to be able to achieve commensurate ...
