eraction between the two with tissues in the body is different and by comparing those differences in the two images, radiologists can differentiate, characterize, isolate and distinguish body tissues and fluid, leading to breakthroughs in medical imaging. In the old 64-slice CT technology, only one X-ray energy source and one X-ray detector could be utilized at one time. Now, radiologists can run the 'dual energy' system simultaneously, allowing them to better freeze the motion of the heart and obtain diverse information about the anatomy in a single scan.
Radiologists utilize these images to search for narrowing or blockages in the coronary arteries of the heart. Litt continues, "We can use these images to figure out the cause when patients are complaining of chest pain. Specifically, we may be able to characterize different types of atherosclerotic plaque, including whether a patient has any of the type more likely to rupture and cause a heart attack."
Nick Bryan, MD, PhD, Chair of Radiology at Penn, comments, "It's interesting to note that some of the initial dual energy CT experimental development work was actually done here at HUP in collaboration with Siemens, the maker of the system, by Penn Radiology's Dr. Peter Joseph, back in the 1970s. Also, in recent years, some of the proof of principle research done specifically on this new dual energy approach was conducted here at HUP in a collaboration between Dr. Litt and a Siemens scientist."
Bryan adds, "When a patient comes to Penn, they can be assured that our team of radiologists and cardiologists are armed with the scientific expertise and clinical knowledge which will result in the best use of this new dual energy technology for excellent cardiovascular diagnosis and care."
