Purpose
To evaluate the potential for bias in functional magnetic resonance imaging (fMRI) aging studies resulting from age‐related differences in magnetic field distributions that can impact echo time and functional contrast.
Materials and Methods
Magnetic field maps were taken on 31 younger adults (age: 22 ± 2.9 years) and 46 older adults (age: 66 ± 4.5 years) on a 3T scanner. Using the spatial...
In the early days of multimedia research, the first image dataset collected consisted of only four still grayscale images captured by a drum scanner. At the time, digital imaging was only available in laboratories, and digital videos barely existed. Half a century later, the amount of visual data has exploded at an unprecedented rate. Images and videos are now created, stored, and used by the majority...
