We know this is not a sufficiently detailed study to rule out anomalies and that greater detail and skill is required for an anomaly scan.< I beg to disagree. If a comprehensive scan is performed, MOST anomalies should be ruled out. I believe that both AIUM and ACR standards indicate that second and third trimester fetal anatomy should be documented, including, but not limited to, "cerebral ventricles, choroid plexus, posterior fossa (including cerebellar hemisphere and cisterna magna,), four-chamber view of the heart(including its position within the thorax), spine (longitudinal and transverse), stomach, urinary bladder, fetal umbilical cord insertion site and intactness of abdominal wall, and the kidneys." (ACR standards, rev. 1999) If all of the above mentioned anatomy is displayed, then most anomalies (but not all) could be ruled out. I always go one step further, and examine outflow tracts, hands and feet, as well as all extremeties. In my opinion, this should cover a "screening" scan quite well.

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
