Imaging vs spectroscopy
WitrynaO-PTIR submicron visible probe, non-contact, detection of the photothermal IR effect overcomes the key limitation of traditional FTIR/QCL microscopy. It does this by removing the fundamental spatial resolution limits of IR spectroscopy (10-20 microns). This limit is now governed by the visible beam wavelength (.5 micron). WitrynaPurpose We compared the predictive accuracy of early-phase brain diffusion tensor imaging (DTI), proton magnetic resonance spectroscopy (1H-MRS), and serum neuron-specific enolase (NSE) against the motor score and epileptic seizures (ES) for poor neurological outcome after out-of-hospital cardiac arrest (OHCA).
