Question: what is the difference between 2d and 3d mri?
Answer: In 2D MRI a 2D plane in the body is excited and imaged. You can repeat this acquisition for multiple planes to create a stack of 2D images resembling a 3D volume. ... 3D MRI images a stack of contiguous slices i.e. with zero gap between them. 3D MRI has a higher signal-to-noise-ratio per unit time than 2D MRI.
