Classification of clinical significance of prostate lesions using multi-parametric MRI data
Peripheral Artery:Vein Enhanced Segmentation (PAVES)
Peripheral Artery:Vein Enhanced Segmentation (PAVES) is the challenge focussed on providing easily interpretable and relevant images that can be readily understood by clinicians (vascular interventional radiologists & vascular surgeons) from MRA datasets where the venous and arterial vasculature may be equally enhanced. The setting is lower limb arterial occlusive disease where imaging of the below knee arterial vasculature is critical in planning limb salvage interventions. However, the competing demands of the high spatial resolution needed to image small vessels versus imaging time constraints where there is often a very short arteriovenous transit time for contrast passage form arterial to venous compartments makes imaging challenging. While dynamic MRA techniques can usually allow arterial imaging without venous ‘contamination’ these necessarily sacrifice spatial resolution.
