What are 3D-4D-5D Ultrasound Scans?
Parents are always anxious to get the glimpse of the growing baby inside the womb. 2D images show the cross-sectional details of the fetal structures and the environment. These images form the basis for clinical evaluation during the antenatal period. These images are complex and cannot be understood by the anxious patient.
3D-4D-5D ultrasound scans allow the parents to see the unborn baby (fetus) in a more comprehensible manner in terms of looking at the baby’s face. 2D ultrasound provides axial cross-sectional images, 3D Ultrasound provides volume with depth information in the form of still three-dimensional images. 4D Ultrasound provides real-time 3D images in motion. 5D Ultrasound involves more automation options for the operator and ensures speed to the overall workflow. 3D/4D US has evolved into a powerful technique in fetal imaging. 3D/4D US offers useful information regarding the fetal surface, which helps in precise evaluation of the fetal surface structures and plays important role in clinical evaluation of fetal face, fetal extremities and back.
Evidence Healthcare Clinic now also provides 3D & 4D Ultrasound options for evaluation of the Fetuses, during the antenatal US scans. It is however, important to understand that even if 3D, 4D or 5D ultrasound is done, 2D ultrasound will remain the basis for the image interpretation and clinical diagnosis and will always be performed
Safety of Fetal Ultrasound Scanning: It is also crucial to understand the basic facts about the safety of the unborn fetus during scanning. Ultrasound imaging is non-invasive and does not rely on ionizing radiation. 2D Ultrasound is therefore absolutely SAFE for the fetus throughout the pregnancy. Color/Spectral Doppler and 3D/4D/5D Ultrasound should NOT be however, used in the 1st trimester, as the safety is not established in medical literature. During the 2nd & 3rd trimester, they are SAFE and may be routinely used but only under the guidance of an expert Radiologist who understands the basic principles of Ultrasound safety and follow standard protocols and safety guidelines during fetal imaging.
