Some parents today are choosing to have a 30-minute ultrasound performed during the mother's pregnancy in order to receive a 3-D or 4-D image and/or a video of their baby. While it is wonderful keepsake, many health professionals disagree with the practice for a variety of reasons. Unlike an ultrasound done for medical purposes, an ultrasound done to produce keepsakes uses a higher frequency of sound waves and produces more heat for a prolonged period of time. Additionally, the technicians who do the keepsake ultrasounds are generally only trained for that purpose and therefore cannot detect abnormalities with a baby. Little research has been done to assess the effects of this type of ultrasound, therefore the long term effects are not known.
