Detection of Vesicoureteral Reflux using Electrical Impedance Tomography
This study describes a novel approach to detect vesicoureteral reflux (VUR), non-invasively using electrical impedance tomography (EIT). VUR is the backflow of urine from the bladder to the kidneys and predisposes children to urinary tract infections (UTIs) and kidney damage. EIT measurements were taken in a porcine model. Data from 116 experiments were collected, processed and time-difference images reconstructed. Unilateral infusions were successfully detected in 94.83% of all mean voltage signals and in over 98.28% of the reconstructed images. The results show the promise of EIT as a screening tool for VUR in children.
