Sep. 09, 2024 – Better image quality, same reading times or faster, increased confidence in diagnosis, reduced time to potential intervention, and potential to divert cases from CT imaging. This is a summary of a study using the Reveal 35C detector in the ICU, to be presented at this year’s American Society of Emergency Radiology (ASER) Meeting that will take place Sept. 11 to 14 in Washington, D.C.
According to the study: “In certain cases, especially when computed tomography (CT) is not an option, dual-energy X-ray can permit improved visualization of soft tissues by subtracting unwanted structural noise […] and simultaneously reducing unnecessary radiation exposure. Medical lines and tubes can be better visualized using the bone image that dual-energy X-ray detectors also produce.”
Radiologist Vikram Venkatesh, one of the study’s authors, explained the difficulties of imaging in the ICU: “In addition to their critical condition requiring intensive care, ICU patients often have multiple lines, tubes, and implantable devices, making it challenging to transport them to the medical imaging department.”
The study at Grand River Hospital (GRH), a 665-bed community hospital in Kitchener, Ontario, Canada, focused on how the Reveal 35C detector could address these challenges by providing dual-energy images directly at the bedside. Seventeen respondents were interviewed, including radiologists and intensivists.
Results were positive for more than half of the physicians in all areas, with reported better image quality, no added or faster reading times, increased confidence in diagnosis, and a reduction in time to potential intervention.
Another outcome observed was the potential for CT diversion. In addition to the self-reported reduction trend noted by intensivists, data collected at the hospital showed a decrease in the number of chest CTs during the study period compared to other time frames: a 37.5 percent decrease compared to the prior 3 months and a 16.67% decline compared to the identical period in the previous year.
In the ICU, due to the capitated nature of reimbursement, hospitals are encouraged to manage costs effectively. “Along with the cost savings from each avoided CT scan, there are further benefits like avoiding re-intubation, reducing transport risks, and improving infection control,” analyzed Amol Karnick, president and CEO of KA Imaging.
The Reveal 35C flat panel detector is available from KA Imaging.
