Is it Time for a Change in How Structural MRI Data is Collected?
New study shows there is a lot to consider
T1 structural images for the two sequences, MPRAGE and MPRAGE+PMC. The top row shows the MPRAGE sequence, while the bottom row shows the images that were generated with the MPRAGE+PMC sequence. Columns represent two different participants, one with minimal head motion (left, Low-Mover) and another with a large quantity of motion (right, High-Mover). Pial and white matter (WM) surface reconstruction from Freesurfer are also shown.
February 17, 2021 A new paper, Is it time to switch your T1W sequence? Assessing the impact of prospective motion correction on the reliability and quality of structural imaging, evaluates two different ways of collecting magnetic resonance imaging (MRI) structural images. The first type of sequence, called MPRAGE, has been widely used by the neuroimaging research community for the last 20-plus years. More recently, an updated version of this

Male sex, heart disease, and race ranked next after schizophrenia in order.
