BHB: New 3D Unit For Mammography Service
Bermuda Hospitals Board is upgrading its mammography service with a new 3D unit, noting that “the technologies produce clearer images which have a host of medical benefits one of the most important of which is that it improves our ability to detect cancer.”
A spokesperson said, “Bermuda Hospitals Board is upgrading its mammography service with a new 3D unit and possibly the island’s first, automated breast ultrasound unit [ABUS].
“The Pristina 3D mammography unit and the Ivenia Automatic Breast Ultrasound System [ABUS] both from manufacturer GE, will be installed this month. To make room for the new units, the old 2D mammography machine is being removed.
“Mammography and biopsy services have been suspended while the switchover is carried out. Following the installations staff training on the new equipment will take place.
Benefits of 3D mammography
“Research has shown that 3D mammography locates more cancers than its 2D predecessor and also reduces the number of false positives. In 2D mammography, two X-ray images of the breast are used. Three-dimensional [3D] mammography creates a 3D picture of breast tissue using X-ray images of several different angles around the breast.
Benefits of Automated Breast Ultrasound
“In mammograms both the healthy dense breast tissue, and cancer, appear white. This makes cancer detection more difficult in those with dense breasts. Seventy-one percent of cancers occur in dense breasts and studies show that over 1/3 of cancers in dense breasts are missed in mammograms.
“Cancer detection in dense breast tissue significantly improves with the use of a specially designed ultrasound device –ABUS. The combination imagery of X-rays [from the 3D mammogram] and sound waves [from the ultrasound] produce a much clearer picture of the dense breast tissue. Cancer cells appear black in ultrasound imagery, while the dense breast tissue appears white. This makes it easier for radiologists to detect cancer cells.”
“Imaging Services staff are excited about this upgrade and eager to start using the advanced technology,” said Diagnostic Imaging Clinical Manager Renee Butterfield.
“The installations represent significant improvement in service we provide the public,” said Chief of Diagnostic Imaging Daniel Stovell, MD. “The technologies produce clearer images which have a host of medical benefits one of the most important of which is that it improves our ability to detect cancer.”
