Functional preservation and reorganization of brain during motor imagery in patients with incomplete spinal cord injury: a pilot fMRI study

Frontiers in Human Neuroscience, 2016
Motor imagery (MI) is a cognitive process involved in mentally rehearsing movement representations, and it has great potential for use in the rehabilitation of motor function in patients with spinal cord injuries.

Occult Spinal Dysraphism in the Presence of Rare Cutaneous Stigma in a Neonate: Importance of Ultrasound and Magnetic Resonance Imaging

Case Reports in Medicine, 2013
Occult spinal dysraphism is defined as a group of dystrophic conditions below an intact cover of dermis and epidermis. Ultrasonography using linear transducers is a fast, inexpensive, and effective method that makes it possible to view the content of the

Susceptibility effects in nuclear magnetic resonance imaging [PDF]

arXiv, 2017
The properties of dephasing and the resulting relaxation of the magnetization are the basic principle on which all magnetic resonance imaging methods are based. The signal obtained from the gyrating spins is essentially determined by the properties of the considered tissue.

Magnetic resonance imaging of perfusion using spin inversion of arterial water

Proceedings of the National Academy of Sciences of the United States of America, 1992
A technique has been developed for proton magnetic resonance imaging (MRI) of perfusion, using water as a freely diffusable tracer, and its application to the measurement of cerebral blood flow (CBF) in the rat is demonstrated.

Magnetic Resonance Imaging in Cardiology

Journal of the Royal College of Physicians of London, 1999
Magnetic resonance imaging (MRI) provides accurate, highly reproducible tomographic images in any desired anatomical plane, making it ideal for imaging all structural abnormalities The reproducibility of MRI makes it ideal for serial analysis and follow-up MRI is safe, non-invasive and does not require ionising radiation MRI provides accurate ...

Effect of Anodal Direct-Current Stimulation on Cortical Hemodynamic Responses With Laser-Speckle Contrast Imaging

Frontiers in Neuroscience, 2018
Transcranial direct-current stimulation (DCS) offers a method for noninvasive neuromodulation usable in basic and clinical human neuroscience. Laser-speckle contrast imaging (LSCI), a powerful, low-cost method for obtaining images of dynamic systems, can
