A/Prof Fergus Scott
MB BS (UNSW), FRANZCOG, DDU, COGU
Fergus Scott is an Associate Professor at the University of New South Wales. He graduated from Monash University in Melbourne. He undertook subspecialty training in the Fetal Medicine Units at King George V Hospital, Sydney and in the Mater Hospital, Brisbane. On completion of his subspecialty training he was the only Australian obstetrician with two subspecialties in both Maternal Fetal Medicine and Obstetric and Gynaecological Ultrasound.
Fergus has served as an examiner for the Diploma of Medical Ultrasound and the Diploma of Diagnostic Ultrasound, as well as being on the Medical Council of the Australasian Society of Ultrasound in Medicine (ASUM) and became the ASUM President. He was on the medical council of the World Federation of Ultrasound in Medicine and Biology representing ASUM, as well as being on the subspecialty committee for Obstetric and Gynaecological Ultrasound for the Royal Australian and New Zealand College of Obstetricians and Gynaecologist and is a past chairman of that committee.
Fergus first started working with Sydney Ultrasound for Women (SUFW) in 1996 and became a partner six months later. “Dealing with healthy people having a child is one of the few happy events in medicine,” commented Fergus. “One area of this that makes a real difference is ultrasound and prenatal diagnosis.”
Although dealing with what is perceived as women’s health, Fergus tends to think of it as the reproductive health of the couple. “Although much of it affects the female physically, it is usually a couple that enjoys the good news or copes with the bad news,” said Fergus.
His main interest had been in prenatal diagnosis and prenatal screening, including NIPT, Nuchal Translucency, CVS and amniocentesis. It is an area he believes makes the most difference. The affect of abnormality on a child involves the whole of its life and the affect on the family is enormous.
Fergus said Sydney Ultrasound for Women is often used for second opinions by other practices. Having respect from his medical peers is absolutely imperative. “The majority of our patients are referred to us by obstetricians and GPs and their trust in our ability has been instrumental in the growth of Sydney Ultrasound for Women.”
“We try to provide an all-encompassing care package from an obstetric and gynaecologic point of view,” he said. “We aim to operate at the leading edge of our field. When developments emerge regarding prenatal diagnosis, we try to adopt them as soon as possible.”
“Having introduced NT screening into Australia, and now being the largest provider of NIPT, we feel that we are producing the best results the test is capable of achieving and try to improve with each new technological development.”
