Simple Reduction Technique Decreases Radiation Dose Associated With CT Scans Of The Head
Z-axis modulation can significantly reduce the radiation dose associated with unenhanced computed tomography (CT) scans of the head, according to a study presented May 6 at the ARRS 2010 Annual Meeting in San Diego, CA. Z-axis modulation is a simple technique that radiologists can use to adjust the radiation dose and obtain optimal image quality during CT scans.
"As radiologists, we are constantly looking for ways to reduce the radiation dose associated with advanced imaging exams such as CT. Our study looked at the effects of z-axis modulation for CT head protocols on patient dose and image quality," said Thomas Zacharia, MD, lead author of the study.
"Utilization of the z-axis modulation technique for CT head examinations offers significant radiation dose reduction while image quality is optimally obtained," he said.
