Multiplanar reformation (MPR) is the process of using the data from axial CT images to create nonaxial two-dimensional images. MPR images are coronal, sagittal, oblique, or curved plane images generated from a plane only 1 voxel in thickness transecting a set or stack of axial images.
Multiplanar reconstruction (MPR) is a method of displaying three-dimensional datasets. The authors assessed the usefulness of MPR for evaluating knee MRI datasets by comparing readers’ performance using MPR and conventional film MRIs.
The 3D MPR tool provided within the RadiAnt DICOM Viewer can be used to reconstruct images in arbitrary planes (oblique). This can help to create a visualization of the anatomy that would not be possible using base images alone.
Multiplanar reformation or reconstruction (MPR) involves the process of converting data from an imaging modality acquired in a certain plane, usually axial, into another plane 1. It is most commonly performed with thin-slice data from volumetric CT in the axial plane, but it may be accomplished with scanning in any plane and whichever modality is capable of cross-sectional imaging, including magnetic resonance imaging (MRI), PET, and SPECT.
The acquired data, for example from the axial plane, can then be converted to non-axial planes such as coronal, sagittal or oblique. In addition, with the aid of various software, several manipulations of the data can be made. One of these methods, called curved planar reformation (CPR), involves tracing a structure, usually a blood vessel, and generating a planar (two-dimensional) image that transects the structure along its short axis. This is very useful in CT/MR angiography (CTA).
