Acoustic radiation force imaging (ARFI) in the non-distended bladder does not predict abnormal urodynamic parameters in children

Introduction: Acoustic radiation force imaging (ARFI) is a recently developed form of ultrasound imaging that allows in-vivo measurement of tissue stiffness. This technology could be useful at predicting bladder compliance in children. We hypothesize that tissue stiffness, as measured by ARFI, correlates with abnormal bladder compliance and capacity in patients with bladder dysfunction. Methods: Patients who presented for cystometrography...
