In 1958 Ian Donald, Regius Professor of Midwifery at the University of Glasgow, and his colleagues John MacVicar, an obstetrician, and Tom Brown, an engineer, published a paper in The Lancet entitled "Investigation of Abdominal Masses by Pulsed Ultrasound." This article described their experience using an ultrasound scanner on 100 patients, and included 12 illustrations of various gynecologic disorders (eg, ovarian cysts, fibroids) as well as demonstration of obstetric findings such as the fetal skull at 34 weeks' gestation,"hydramnios" (polyhydramnios), and twins in breech presentation. The somewhat grainy and indistinct "Compound B-mode contact scanner" images were the first published obstetrical or gynecological sonograms.
