Three-Dimensional-Wall Motion Tracking

Three-Dimensional-Wall Motion Tracking: A New and Faster Tool for Myocardial Strain Assessment: Comparison With Two-Dimensional-Wall Motion Tracking
JASE Volume 22(4), April 2009, p 325–330
.
Conclusions:: Three-dimensional WMT provides a faster, more complete, and similar analysis to assess LV longitudinal and radial strain compared with 2D WMT. Thus, 3D WMT is a potential clinical bedside tool for quantifying myocardial strain.
.
Three-dimensional WMT provided complete radial and longitudinal LV strain information, similar to 2D WMT (P = NS), but it was less time consuming: the times for acquisition and analysis were 14.0 ± 1.9 minutes with 2D WMT and 5.1 ± 1.1 minutes with 3D WMT (P < .001).

Veja a importância da informação acima. Um exame com 2D leve 10 minutos a mais para a aquisição da imagem que o método 3D
.
Primeira justificativa econômica válida para a aquisição de um 3D para ecocardiografia.
.
Com economia de 10 minutos por exame, dá para fazer 1 exame a mais por hora, 8 exames a mais por dia.
