N.T.
Hi N.,
I went to this place a couple years back, right in Glendale: http://www.mybaby4d.com/3d4dultrasound.html
I wouldn't say the quality is great, but my baby girl was not very cooperative for ANY ultrasound! Some doctor's offices offer the service as well - obviously, it is not covered by insurance. I think my office charges $150. Ask your OB!
