Model saves time, radiation by simulating anatomic changes during radiotherapy

By Eric Barnes

Organs and tumors can twist, turn, and deform substantially during radiotherapy, creating a moving target for treatment planners seeking to avoid irradiating normal tissue. One solution, a full CT scan before each treatment, is both time- and radiation-intensive. But what if doctors could simply "update" the pretreatment scan with a few newly acquired planar projection images? Researchers from Virginia built and tested a model to do just that.

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.

4D MRI enables blood-velocity measurement in mitral valve insufficiency

By Eric Barnes

BERLIN - Mitral valve insufficiency is a fairly common heart problem that lacks ideal imaging solutions. The problem lies in assessing regurgitant blood flow to determine the need for intervention. A presentation Thursday at the Computer Assisted Radiology and Surgery (CARS) meeting discussed the limitations in assessing blood flow, and highlighted a new measurement approach using time-resolved MRI vector fields.
