2D-3D ULTRASOUND

2D ultrasound gives you outlines and flat looking images, but it can be used to see the internal organs of the baby. This is helpful in diagnosing heart defects, issues with the kidneys, and other potential internal issues.

Three‐dimensional (3D) ultrasound is gaining popularity in prenatal diagnosis. While there are no studies regarding the safety of 3D ultrasound, it is now widely performed in non‐medical facilities, for non‐diagnostic purposes. The present study was aimed at comparing the acoustic output, as expressed by thermal index (TI) and mechanical index (MI), of conventional two‐dimensional (2D) and 3D/4D ultrasound during pregnancy.
