A new study shows: X-Rays Overused in ICU: Ultrasound Safer, Just as Effective
“We found that the use of ultrasound to diagnose patients greatly reduced radiation exposure for patients without negatively affecting their health,” said Margarita Oks, MD, Long Island Jewish Hospital, North Shore-LIJ Health System. “It was also cost-effective.”
Ultrasound, also called sonography, is an imaging method that uses high-frequency sound waves to produce images that lead to diagnosis and treatment of many diseases and medical conditions. Radiation is not used in ultrasound testing, but is used in x-rays and CT scans.
Dr. Oks and her colleagues studied medical charts covering 3 months of data comparing chest x-rays, CT scans, and ultrasound between two independent but similar medical intensive care units staffed by the same medical house staff in one health-care system. One unit used bedside ultrasound as the standard of care for diagnosis; the second used conventional imaging, such as x-rays and CT scans, as its standard of care in diagnosis.
