Faster scans may reduce study costs and patient attrition by accommodating people who cannot tolerate long scan sessions. However, little is known about how scan acceleration affects the power to detect longitudinal brain change. Using tensor-based morphometry, no significant difference was detected in...

Brain segmentation in magnetic resonance imaging (MRI) images is the process of isolating the brain from non-brain tissues to simplify the further analysis, such as detecting pathology or calculating volumes. This paper proposes a Graph-based Unsupervised Brain Segmentation (GUBS) that processes 3D ...
Functional MRI (fMRI) is a specific brain scan to measure brain function. It is used to determine what parts of the brain are working during a scan. Because different parts of the brain control each body function, blood flow can be mapped as the patient is asked to do a specific task,...
To determine a worst-case level of acoustic noise generated by the operation of the Impulse gradient coil, a series of acoustic noise measurements was performed using a Bruel and Kjaer 2260 Observer sound level meter. A spectrum of the acoustic noise was generated by pulsing all three gradients...
Brain structure in later life reflects both influences of intrinsic aging and those of lifestyle, environment and disease. We developed a deep neural network model trained on brain MRI scans of healthy people to predict “healthy” brain age. Brain regio
image reconstruction,automatic brain tissue segmentation and volume measurement. This paper will introduce the basic principle and function of SyMRI technology,review the application progress of SyMRI technology in the diagnosis of craniocerebral diseases,summarize its advantages and limitations,It aims to ...
This prospective study included all consecutive neonates with HIE admitted to the neonatal intensive care unit of our institution between April 2015 and December 2017. The criteria of national guidelines (Saliba and Debillon, 2010) were used to determine eligibility for therapeutic hypothermia. All inc...
brain scanning; magnetic resonance imaging (MRI)Magnetic resonance imaging (MRI) is used to detect certain types of intracranial abnormalities. With the development in the mid-1970s of the CAT scan, computer-based technologies have revolutionized the field of medicaldiagnosis. One of the more signif...
In addition to structural imaging, MRI can also be used to visualize functional activity in the brain. Functional MRI, or fMRI, measures changes in blood flow to different parts of the brain. It is used to observe brain structures and to determine which parts of the brain are handling critic...
