Don’t Skip Chest CT in the ER Just Because X-Ray Checks Out Okay, Warns Study

18.05.2005


Chest X-rays may miss 40% of clinically significant thoracic injuries in multiple trauma patients that can be caught by chest CT, say researchers from Massachusetts General Hospital in Boston.



For the study, the researchers analyzed the findings of 563 multiple trauma patients who had both chest CT and plain film X-rays performed. They found that the X-rays missed 40% of clinically significant thoracic injuries, including lung contusions, lung lacerations, rib and spine fractures and air or blood trapped in the space between the lung and chest wall.

“The average multiple trauma patient, say from a fall or motor vehicle accident, will get a head CT, cervical spine CT, chest CT, abdomen CT and pelvic CT, basically from head to thighs,” said Robert A. Novelline, MD, senior author of the study. “Today this takes about three to five minutes-10 years ago it would take two hours, but the newest generation of CT scanners, called multidetector CT (or MDCT) has revolutionized the imaging of multiple trauma patients,” he added.


However, say the researchers, multiple trauma patients also first receive portable chest X-rays upon entry into the emergency department. “A doctor would get the chest X-ray done, and then order a CT, but tell the radiologist to omit the chest part of the CT because the X-ray was already performed and showed no problems for the patient. We wanted to see if avoiding chest CTs for this reason was really a good idea,” said Dr. Novelline.

According to the researchers, 49 million patients entered trauma centers last year, each of whom received an average of one imaging procedure apiece. Of those imaging procedures, 25-30% were CT scans. “Some are saying that we are imaging too much, but this study shows that for optimum care of trauma patients high-tech imaging like MDCT is worth it and needs to be performed,” said Dr. Novelline.

The full results of the study will be presented on May 18 during the American Roentgen Ray Society Annual Meeting in New Orleans, LA.

The American Roentgen Ray Society (ARRS) was founded in 1900 and is the oldest radiology society in the U.S. Radiologists from all over the world attend the ARRS Annual Meeting to take part in instructional courses, scientific paper presentations, symposiums, new issues forums and scientific and commercial exhibits related to the field of radiology. The ARRS is named after Wilhelm Röentgen, who discovered the x-ray in 1895.

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
