Multi Planar Reconstruction is a method used in medical imaging that creates new views in different directions from scan images, such as those from a CT (computed tomography) or MRI (magnetic resonance imaging) scan.
How does Multi Planar Reconstruction work?
During a CT or MRI scan, many individual slice images are produced that show the body in very thin layers. These slices are usually taken in one direction, most often from top to bottom (axial). Multi Planar Reconstruction, often called MPR, uses this data to calculate images in other planes. This makes it possible to show views from front to back (coronal) or from the side (sagittal).
This means that structures or changes in the body can be looked at from different angles, without the need for a new scan. It makes it easier to assess organs, blood vessels, or bones, and helps to make hidden or hard-to-spot findings visible.
What is Multi Planar Reconstruction used for?
Multi Planar Reconstruction plays an important role in many areas of diagnosis. It is especially helpful when complex structures need to be assessed. In spine diagnostics, for example, it can show more clearly how far a slipped disc extends or whether vertebrae have shifted. When examining joints, blood vessels, or tumours, reconstruction from different planes also provides valuable additional information.
Another benefit is that with MPR, doctors can focus in on a specific structure and display individual organs or abnormalities in isolation. This improves the overall picture and makes it easier to plan procedures or further investigations.
What does this mean for a scan report?
If Multi Planar Reconstruction is mentioned in a scan report or doctor's letter, it means that the images were assessed not only in the original slice plane but also in other directions. This increases the accuracy of the diagnosis and can help to identify changes in tissue more clearly.
As a patient, the mention of Multi Planar Reconstruction does not directly affect your treatment or outlook. It is a technical method that simplifies and improves image assessment for the medical team. The scan itself remains exactly the same for you, and no additional burden or risks are involved.
The difference from other reconstruction methods
Alongside Multi Planar Reconstruction, there are other techniques that calculate new views from scan images. One example is 3D reconstruction, which creates a three-dimensional model of the area of the body being examined. Whilst MPR mainly serves to produce two-dimensional views in different planes, 3D reconstruction goes one step further and allows a spatial representation.

A brief summary
Multi Planar Reconstruction is a tool in modern imaging that makes it possible to display slice images from CT or MRI scans in different directions. For medical diagnosis, this is a great advantage, as changes in the body can be viewed from several angles. As a patient, this does not create any additional burden for you. It simply improves the quality and depth of information from the scan.
