3D diminution index spots lung nodules attached to blood vessels
By Eric Barnes
BERLIN - A principal limitation of lung cancer imaging is the difficulty of distinguishing lung nodules attached to blood vessels from normal blood vessels, especially in CT data. But researchers from Japan have developed a 3D feature called the diminution index, which scans the CT pulmonary blood vessel data for signs of rapidly expanding shapes that can indicate a nodule rather than a blood vessel.
