Multiplanar Reconstruction (MPR)

Multiplanar Reconstruction (MPR) allows images to be created from the original axial plane in either the coronal, sagittal, or oblique plane. Spiral/helical CT has greatly improved the quality of MPRs by eliminating the 'stair-step' artefacts that used to occur with conventional slice-by-slice CT. Multislice CT has further improved the quality of MPRs as it allows isotropic imaging in which the image quality of the reconstructed MPR is the same as the original axial image.
