Does intravascular ultrasound accurately measure dynamic changes in aortic dimensions compared to implanted sonomicrometers in dogs?
IVUS is a feasible and reliable method for measuring dynamic changes in aortic dimensions, despite slight underestimation compared to sonomicrometers.
Hardt et al. (1999) studied this question.
