3D vs 2D and materno fetal
                          bonding.
• Three-dimensional images may facilitate
  recognition of the fetus, but 3D US did not have
  higher impact on maternal–fetal bonding

• Positive infuence of 3D ultrasound with regard to
  maternalperception of their fetuses

• Eighty-two percent of the patients,irrespective of
  the order of the examinations, reported a higher
  preference for 3D pictures, either due to
  closeness to reality or better perceptibility.
  Arch Gynecol Obstet (2007) 276:475–479
3D vs 2D and materno fetal
                          bonding.
• 3DUS appears to more positively influence the
  perceptions of mothers to their babies postbirth
  compared to 2DUS
• 70 % of the 3DUS mothers compared to 56% of
  the 2DUS mothers felt that they already „knew‟
  their baby immediately after the baby was born
  because of the ultrasound (P = 0.009,


Ultrasound Obstet Gynecol 2005; 25: 473–477
4D and prenatal bonding: still more
                   questions than answers
• “antenatal bonding was literally kick-
  started by the onset of fetal movements
• The other missed opportunity was not to
  assess the impact of moving 3D
• No randomized study has assessed the
  bonding effect of 4D ultrasound in the third
  trimester”

S Campbell . Ultrasound Obstet Gynecol 2006; 27: 243–244
Missatges finals eco 3D-4D

• La utilització de plans virtuals , la navegació
  multiplanar i la reconstrucció permeten
  complementar la capacitat diagnòstica en
  patologia fetal
• Es reproduible i permet l‟anàlisi exhaustiu “off-
  line” (TELEMEDICINA)
• Accés detallat al comportament fetal intraúter.

• Millora percepció del fetus com a fill en Eco 3 D.

rebanadas si puedes tener la
