EIC Accelerator

A new peer-reviewed research article was published in the journal of vascular and interventional radiology

Research highlights In contrast to digital subtraction angiography (DSA), digital variance angiography (DVA) does not use a mask but calculates the standard deviation, variance and other time-derived parameters of the X-ray attenuation for each pixel in an unsubtracted image series, resulting in suppression of noise and high image quality (IQ). This study evaluated two different DVA algorithms in selective lower limb angiography using iodinated and carbon dioxide contrast media, using unsubtracted source files from DSA. Compared with DSA, DVA provided higher contrast-to-noise ratio and better IQ irrespective of contrast agent used. The conventional DVA algorithm yielded better IQ than the new algorithm.
