These noninvasive multimodal neuroimaging techniques can be used to explore and better understand processes underlying the functional brain organization.
A diferencia del TAC o de las radiografas simples no usa radiaciones ionizantes (rayos X).
Se basa en el procesamiento de ondas de radio que pasan por el paciente, el cual es sometido a un potente campo magntico. We have shown that interleaved acquisition allows to obtain reliable P300 data and fMRI results, likely to shed light on the anatomical location of brain regions involved in cognitive ERPs relevant to many disorders affecting CNS functions. La resonancia magntica nuclear (RMN) es una prueba diagnstica con la que se obtienen imgenes del interior del cuerpo. Radiologie i imagistic medical Cluj Servicii medicale oferite de. The fMRI maps acquired concurrently showed stronger BOLD response for target condition. RMN CT PET CT Radiologie Ecografie Rezonanta magnetica (RM) Radiologie digitala. Novel-related ERPs were of higher amplitude than their target-related counterparts. Interleaved EEG/fMRI acquisition evidenced two P300 ERPs evoked at Fz, Cz, and Pz by targets and novels. The post hoc filter presented here was designed and applied to EEG data to remove the cardiac pulse artifact. The stimuli, including rare targets "X," frequent repetitive distractors "O," and rare distractors referred to as novels, were randomly presented every 2 +/- 1 s. Ten EEG channels were acquired interleaved with fMRI images in five healthy subjects. Compania Hellimed furnizeaza servicii si echipamente medicale de inalta performanta pentru cardiologie, terapie intensiva, cardiologie, neurologie, ORL. Here, we demonstrate the feasibility of recording P300 ERPs during fMRI using a three-stimulus visual oddball task and involving a small number of trials for each stimulus. It is important in cognitive studies to ensure that recorded data reflect the same brain activity, and this is achieved through interleaved electroencephalographic (EEG) and fMRI measurements. However, EEG data recorded inside an MR scanner is heavily distorted by artifacts. Analysis of combined event-related potentials (ERP) and functional magnetic resonance imaging (fMRI) can provide a high temporal and high spatial resolution to study functional cerebral processes.
