Example - Overcoming the Partial Volume Effect

Lung tumour (7x ROI, before enhancement, with edges marked) at WW/WL = 238/70.

Partial Volume Effect (PVE) region of lung tumour visible at WW/WL = 1074/-150.

Partial Volume Effect (PVE) tumour region invisible at WW/WL = 238/70.


Within the outlined region, the appearance or disappearance of part of the lung tumour depends on the window WW/WL settings, but the edge-profile is, of course, independent of any window WW/WL settings.
