During dipyridamole stress echocardiography RT-3D imaging is highly feasible and shows a high concordance rate with standard 2D stress echo. 2D images take longer time to acquire and RT-3D is more time-consuming to analyze. At present, there is no clear clinical advantage justifying routine RT-3D stress echocardiography use.

Estudos comparando 2D com 3d são antigos, usam Dobutamina ou Dipiridamol(?!?!?)
Pior, usam um método volumétrico para estudar espessamento, um parâmetro bidimensional.
