Re: Cisterna Magna. nucal foldFrom: Terry J. DuBose (tjdubose@juno.com)Wed Aug 12 06:12:00 1998
Dear Nancy, you have asked some basic questions that every sonographer should understand. I have to ask what kind of training have you had to be performing Diagnostic Sonography? You do not indicate if you are a professional health care worker or not. On Ultrasound@OBGYN.net, which is specifically designed for professional, we like the opportunity of knowing with whom we are discussing issues. I would advise you to consult some good textbooks on fetal sonography. Briefly, an enlarged cisterna magna is associated with a Dandy Walker type cyst, among other things. A missing CM may be associated with spinal defects. Two vessel umbilical cords are associated with other fetal anomalies. Thickened nucal fold has some association with Down's. The fetal heart requires substantial experience for analysis... it is not for beginners. Now would you please extend us the courtesy of identifying yourself?... and get some training and take the ARDMS examinations before performing Diagnostic Sonography. Thanks. Peace, Terry J.

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.
