Transabdomically, the ultrasound is being used to assess the breast tissue, as the mammary glands have already been enlarged by surgery.
In rectal ultrasounds, which are often used to examine the bladder, the breast is being stimulated and the ultrasound waves are travelling through the tissue, creating an image.
It is a less invasive procedure than transabDOM.
Al Jazeera’s Nick Macfarlane, reporting from Sydney, said that in Australia, “a majority of women have the transabd ultrasound”.
But the ultrasound devices were only introduced in Australia in 2017, and they were only available for women aged 18 to 49.
“In the US, women have access to transabductor ultrasound, which is a much more invasive procedure,” Macfambo said.
“But the difference in the UK is they don’t have transabduction devices.”
He added that in the US the technology has not caught on.
“You’d have to be pretty savvy to use transabectors in the first place.
They’re expensive and they don and you have to wait for a year or so for them to be introduced,” he said.
