3D Evaluation: Image Postprocessing

85 3D Evaluation: Image Postprocessing

Three-dimensional (3D) imaging techniques in MR provide image data sets that can be further processed to create additional representations of anatomy or pathology.

Multiplanar Reconstruction (MPR)

With multiplanar reconstruction, images can be calculated for an infinite number of orientations within the acquired volume. The reconstruction is not necessarily restricted to planes, but can also be performed along curved surfaces. Figure 85.1 illustrates (A) an oblique sagittal reconstruction through the anterior cruciate ligament of the knee, from a 3 T 3D acquisition (using the scan technique SPACE) with 0.5 × 0.5 × < 0.6 mm³ voxel dimensions, and (B) an oblique coronal reconstruction from the reference line defined in (A).
