Reconstruction of 7T-Like Images From 3T MRI

Z-spectrum asymmetry : from 3T to 7T

Introduction: Magnetization Transfer and technically related effects such as CEST are important sources of contrast in MRI. Studying MT in vivo at 7T is challenging due to the increase in longitudinal relaxation time and SAR limits. To overcome this, we use pulsed saturation with EPI readout (MT-EPI) to measure MT at a range of offset frequencies and on the approach to steady-state in a reasona...

3D Reconstruction of Brain Images from 2D MRI Images

Brain is the most important part of the human body. It consist of different types of encephalic tissues .The boundary of each of these encephalic tissues, which makes up the brain, is highly irregular. So, traditional 3-D reconstruction algorithms, using brain MRI images do not give accurate reconstruction. Two class Support vector machines are found to be very successful for pattern recognitio...

Comparison of Robarts’s 3T and 7T MRI Machines for obtaining fMRI Sequences

3D Reconstruction of Plant Roots from MRI Images

We present a novel method for deriving a structural model of a plant root system from 3D Magnetic Resonance Imaging (MRI) data of soil grown plants. The structural model allows calculation of physiologically relevant parameters. Roughly speaking, MRI images show local water content of the investigated sample. The small, local amounts of water in roots require a relatively high resolution, which...

Contribution of subpial pathology to cortical thinning in multiple sclerosis: a combined 7T - 3T MRI study

Introduction. In patients with multiple sclerosis, whether cortical lesions and cortical atrophy reflect two different aspects of the same degenerative process, or have different biological substrates, has not yet been clarified. It is unclear when cortical disease is a consequence of white matter (WM) demyelination with secondary axonal damage leading to neuronal loss (secondary cortical patho...
