interleaved acquisition
MRI scanning technique where brain slices are acquired in alternating order rather than sequentially to minimize cross-talk between adjacent slices.
Full Definition
Interleaved acquisition is an MRI data collection strategy where brain slices are acquired in a non-consecutive order, typically alternating between odd and even numbered slices. This approach minimizes electromagnetic interference between adjacent slices (cross-talk) that can degrade image quality and reduce signal intensity. Interleaved acquisition is commonly used in functional MRI studies to maintain temporal resolution while ensuring consistent image quality across all brain slices.
Usage
Usage note: Distinguish clearly from 'simultaneous multi-slice' which is a different acceleration technique.
