Skin condition and ultrasound imagingFrom: Wolfgang Moroder, MD (womorode@tin.it)Sat Mar 30 08:38:03 2002
Many of my collegues and I have the suspicion that the cosmetic abdominal skin treatment with different ointments, gels or lotions specially in pregnancy alters ultrasound transmission. I did not find any studies dealing with this issue exept the following: In Vivo Examination Of Effects Of Creams And Ointments On Stratum Corneum Using 100 MHz Sonography http://www.mcmaster.ca/inabis98/newtech/kaspar0548/two.html The study concluded: "The thickness increase of the stratum corneum is due to an increase in humidity, which is a direct effect of water-containing externals or which is due to a reduction of vaporisation in fat-containing externals. We observed the following effects of locally applied externals on the ultrasound image: - a significant thickening of the stratum corneum on the finger pads, - a change of the echo intensity of the upper stratum corneum and - a reduction of the echogenicity of the skin entry echo after a long application time." I wonder if the thickness of the fat layer is the only responsible variable for what we define as maternal habitus when unhappy with our imaging power. Best regards. Wolfgang Moroder M.D.

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.
