How Early In Pregnancy Can Ultrasound Detect
An ultraound, also known as a sonogram, is a painless and relatively inexpensive imaging test that utilizes sound waves instead of ionizing radiation. There are no side effects. Ultrasound can give us two-dimensional, and in some applications three-dimensional, images of structures and organs in virtually any part of the body.

We count from the first day of the last menses for OB dating. We can see the pregnancy before 6 weeks but usually just the sac and adding the fetal pole makes things a bit more accurate. Best wishes. ...Read moreSee 1 more doctor answer

"Dating" a fetus: The "dating" refers to the gestational age of the developing fetus not a social romantic encounter. Ultrasounds are only accurate plus or minus 2 weeks gestation unless done serially.(more than one). 'That is why OB MD's use multiple parameters to date pregnancies including LMP(last period), pelvic exam uterine size, etc. "Dating" is an inexact science in life and medicine. ...Read moreSee 1 more doctor answer
Depends on purpose: If the goal is to look at baby for seeing normal fetal anatomy, the earliest would be 18 weeks. This allows the m ajor organ systems to be formed to the point of being able to be evaluated. Before 18 weeks the heart has not finished forming and therefore a scan performed prior to this date does not really look at the normally formed fetal heart but a precursor. ...Read more
