Abstract [en]

We present a new approach to visualising parametric volumes obtained in voxel-wise model fitting of dynamic contrast-enhanced

(DCE) MRI data of the breast. The visualisation makes use of hardware accelerated rendering to obtain an interactive, 3D colour-correct maximum intensity projection (MIP). The method has been realised in software that permits the user to not only interactively visualise the parametric volume but also to delineate 3D regions of interest using a 2D slicewise interface. Experimental results, based on 14 DCE-MRI data sets from routine clinical practice, show that using the visualisation/tracing tool a medically qualified operator can achieve the same sensitivity for the detection of malignancy as a radiologist using conventional manual interpretation, but with better specificity. The results demonstrate that the visualisation methodology/software has potential as a tool for assisting the radiologist with the task of interpreting 4D DCE-MRI data in the routine clinical setting.
