Commercial ultrasound ===================== * Edward J. Cormode Re: “Proliferation of prenatal ultrasonography.” 1 I was recently made aware of what appears to be a proliferation of the availability of commercial fetal ultrasound. A young couple wanted to show me a 60-minute video ultrasound of their 34-week fetus obtained over a two-hour session during which time the uterus was poked and proded to get the baby to wake, move, suck her thumb, etc. The couple told me they were aware of friends that were also getting fetal video ultrasounds in other locations. The authors of this paper express concerns about excessive prenatal ultrasound exposure. Are they aware of what appears to be a new trend mentioned above? ## Footnotes * **For the full letter, go to:** [www.cmaj.ca/cgi/eletters/182/2/143#278694](http://www.cmaj.ca/cgi/eletters/182/2/143#278694) ## REFERENCES 1. 1.
