syngo^® iFlow* has the potential of changing the way in which digital subtraction angiography (DSA) images are evaluated. The application allows the creation of a single static image displaying dynamic information – making flow visualization easier. It shows the user the history of the contrast media through the vessels in full color, at the click of a button. This dynamic flow evaluation provides a greater understanding of the contrast flow within the pathology, greater ease in visualizing the success of a procedure, and assists the clinician in image review by showing a complete DSA run in a single image.

Charles M. Strother, MD, Professor of Radiology at the University of Wisconsin School of Medicine and Public Health has been able to use the application for imaging arteriovenous malformation (AVM). syngo iFlow provides an excellent composite picture of the entire AVM nidus, the feeding arteries, and the venous drainage from both the AVM and normal brain on one single image. Because of the composite nature of the color-coded image, it is easier to see the relationship between arteries and vein that are filling and emptying at different times.

Strother has also used the application for in-stent stenosis and reports enhanced visualization of the DSA images. He states, “syngo iFlow is a valuable addition to the tools available for the display of 2D DSA acquisitions. It improves the conspicuity of findings on DSA images and seems particularly useful in situations where there are complex flow patterns as well as in evaluating acquisitions done prior to and after a therapeutic intervention.”
