A big THANK YOU to Dave Fornell at Cardiovascular Business for covering the latest study on Dynamic Digital Radiography as published in Radiology.
In the original Radiology article, Yamasaki Y et al report the clinical utility of using Dynamic Digital Radiology (DDR) to estimate rapid pulmonary regurgitation severity before irreversible right ventricular failure in patients after Tetralogy of Fallot repair. The study reports that DDR is “A novel dynamic chest radiography technique (that) can be used to easily and rapidly detect severe pulmonary regurgitation, demonstrating excellent diagnostic performance.”
As Dave wrote in his article, the “technique only requires a scan of 7 seconds to capture sequential chest images while the patient holds their breath. It was found to have an accuracy rate of 93%. They said this method can be used to help diagnose patients who cannot undergo traditional diagnostic methods, it can improve access to accurate diagnosis, and offers greatly improved efficiency.”
Dave also shared that “Unlike MRI or CT, the exam does not require contrast. It also has a minimal radiation dose of about 0.2 mSv, which is far lower than a standard chest CT of 6 mSv. The authors said implementation of their new technique may broaden access and reduce healthcare costs. Yamasaki said DCR might also be able to diagnose other heart diseases, like heart failure and pulmonary hypertension.”
