October 19, 2010 – A new high-definition (HD) technology reduces blur created by respiration during positron emission tomography/computed tomography (PET/CT) studies. The Siemens HD Chest provides full HD lesion detection and improved standardized uptake value (SUV) quantification.
The technology was announced earlier this month at the European Association of Nuclear Medicine congress in Vienna, Austria.
By providing a highly automated, amplitude-based gating technology, HD Chest images the chest and upper abdomen in high definition and eliminates the fundamental problems encountered with phase-based 4-D gating, which can be disruptive and time consuming.
Because breathing motion is chaotic, the direction of motion and its magnitude vary from patient to patient. They also vary from session to session for a given patient, and even from moment to moment within the procedure. HD Chest optimizes each patient’s respiratory curve to automatically produce the highest quality PET image. It intelligently adapts to every patients breathing and automatically selects the optimal data range with the least amount of motion and the highest count statistics.
