CT computer-aided volumetry fast tracks pneumothorax measurement Rebekah Moan Potential deadly traumatic pneumothoraces can be measured in the emergency room with a computer-aided volumetric technique that helps move patients from diagnosis to treatment many times faster than conventional visual assessments of the condition with multislice CT. The new approach, developed at Massachusetts General Hospital, has potential implications for the 30% to 39% of chest trauma patients who develop pneumothorax. Traditionally, radiologists have measured the extent of the condition manually, a task that can take as long as an hour. To aid evaluations, MGH researchers developed a computer-aided volumetry that quantifies pneumothoraces appearing on the patient's CT images in about three minutes.
