In a recent article on the new prenatal diagnostic technique of chorionic villi sampling (JAMA [MEDICAL NEWS] 1983;250:1249-1250), the contribution of ultrasonographer Alan Cadkin, MD, was inadvertently omitted. The six women with at-risk pregnancies underwent the procedure at Dr Cadkin's private outpatient ultrasound office, not at Michael Reese Medical Center, Chicago, although these procedures currently are also being offered at Michael Reese.
