50% radiation reduction with new imaging techniques

A 50% reduction in X-ray dose, while maintaining the image quality needed during image-guided cardiac interventions, is now possible according to results from a study to be at the annual congress of the European Association for Percutaneous Cardiovascular Interventions (EuroPCR), held 21–24 May in Paris.

The clinical study was conducted at the Radboud University Nijmegen Medical Centre (Nijmegen, the Netherlands) between September and November 2012, involving 39 patients with a body mass index (BMI) range of 20–37. During the study, two coronary angiography scans of the same patient were compared: for the first scan conventional interventional X-ray technology was used, while for the second scan new technology (AlluraClarity system with ClarityIQ technology, Philips) was used.

Six independent interventional cardiologists from across Europe (Italy, France, Germany, the Netherlands and Sweden) then evaluated the image quality of these scans, and concluded that compared to conventional X-ray technology, the new technology provided equivalent image quality at 50% less X-ray dose.


AlluraClarity system

“We have extensively explored and tested this new technology at our cardiac center”, said co-author Professor N Reifart. “It now enables us to perform most diagnostic angiographies with at least 50% lower radiation levels, equivalent to less than 1 mSv, with similar image quality as in the past”.

Additional studies on the new technology in the fields of neuroradiology and electrophysiology are ongoing, with results expected later this year.
