Multiplanar reformation or reconstruction (MPR) involves the process of acquiring defined diagnostic slices of information from volumetric data achieved during the scanning process. The volumetric data is commonly referred to as the 'volume' or 'thins'. This volume of data in CT is not necessarily acquired in the axial plane; rather, it is presented in an axial orientation for viewing. The volumetric data can then be reformatted into the typical axial, coronal, sagittal, or oblique planes.
This common use of volumetric data for multiplanar reconstruction explains the flexibility and utility of MPR across other modalities capable of cross-sectional imaging, including, magnetic resonance imaging (MRI), PET, and SPECT.
In addition, with the aid of various software, other manipulations of the data can be made. One of these methods, called curved planar reformation (CPR), involves tracing a structure, such as a blood vessel, ureter or intestine, and generating a planar (two-dimensional) image that transects the structure along its short axis 1. This is very useful in CT/MR angiography (CTA).
Also, reformatted data can be used to generate maximum intensity projections (MIPs) or minimum intensity projections (MinIPs) 1.
