DES X-ray Webinar Sets New High

The recent ICE webinar “Improving Department Results with Single Exposure Dual-Energy Subtraction X-Ray: Clinical, Operational and Financial Benefits” was sponsored by KA Imaging. It was also approved by AHRA for 1.0 Category A ARRT (AHRA Reference: LEC11337, Expiration Date: 07/28/2022).

The webinar was popular setting a new high in registrations with 147 individuals signed up for the session.

In the 60-minute webinar, experts Dr. Karim Karim and Jay Potipcoe reviewed the clinical, operation and financial benefits of Single Exposure Dual-Energy Subtraction (DES) X-ray. After viewing the presentation, attendees now understand dual-energy subtraction (DES) X-ray and the clinical benefits enabled by dual-energy in the early detection of small nodules identification, pneumonia, pneumothorax and coronary calcifications. Attendees also now understand the limitations of the old DES techniques and how a single-exposure detector can overcome those limitations. The presenters also explained the operational and economic benefits that come from using the dual-energy technique; and shared information more about current hospital implementations of single exposure dual-energy X-ray.

Karim and Potipcoe opened the floor to attendees during a question-and-answer session that provided additional knowledge to participants.

One question asked, “Are dual energy radiography and phase contrast X-ray imaging, essentially the same thing?”

“No, they’re not,” Karim explained. “Phase contrast X-ray imaging tries to look at the refraction in the X-ray. So, when an X-ray passes through an object it’s going to deviate slightly from its path because of the interaction in that material. Phase contrast X-ray has not really been clinically demonstrated on full-sized patients. I think it’s still in clinical study for breast cancer. It may not work as well for chest X-ray because the patient volumes are too large. Dual energy, on the other hand, is very different.”

“It’s been around for 40 years and it’s looking at, as I mentioned earlier, the attenuation of different energy X-rays in different materials. So, in so dual energy use of materials, separation technique. Phase contrast is a technique that can highlight soft tissue, but they are very different techniques.”

Attendees provide positive feedback in a post-webinar survey that included the question, “How much new information did you receive from today’s webinar?”

“Good amount of good new information was shared, specifically about the technology on old and new detector design. Very interesting,” Director of Radiology P. Mosebach said.

“Very good information, impressive topic for discussion,” said J. Harwood, a biomed equipment Imaging specialist.

“It was all new to me, I have only reviewed DE X-ray in the past,” Director S. Morris said.
