Is there any difference between a sonogram and an ultrasound? is there any difference between a sonogram and an ultrasound? i've heard gfs refer to both things. are they the same or different procedures?

Technically : Technically speaking, ultrasound is alternating sound pressure with a frequency above the upper limit of human hearing (generally between 3 mhz and 10 mhz). Sonography or ultrasonography is the use of the reflections of these high frequency sound waves to generate an image. The image generated is termed a sonogram. However, when generally used in the medical field there is no difference between "a sonogram" and "an ultrasound"; they are generally considered to be synonymous.

Same exam: Here is a link to detailed information on ultrasonograpy, also called sonography including information on how the procedure is performed. http://www.uchospitals.edu/online-library/content=p01298.
