The large scale North American study was developed by the US based ECOG-ACRIN Cancer Research Group (ECOG-ACRIN) and the National Cancer Institute (NCI), with the Canadian Cancer Trials Group (CCTG) coordinating the trial in Canada (more national sites will be opening the trial over the next several months).
Dynamic multiplanar reconstructions allow the user to adjust reconstruction and display parameters interactively, including axial sampling, slice location, plane tilt…
The Sunnybrook Health Sciences Centre and the Ottawa Hospital are currently enrolling women in the Tomosynthesis Mammographic Imaging Screening Trial (TMIST), the first randomized trial to compare conventional mammography (2-D) to the newer digital tomosynthesis method (3-D).
This allows the radiologist to view the breast in layers without having to look through dense breast tissue above or below each layer.
For the time being, the Food and Drug Adminstration requires that 3D mammography be performed in conjunction with standard 2D mammography.
The test is performed with dedicated tomosynthesis equipment that takes a series of low-dose pictures prior to each mammographic view.
The computer in the unit then takes all those pictures and combines them into a 3-dimensional representation of the breast.Pisano, MD, professor in residence at Beth Israel Deaconess Medical Center and Harvard Medical School, and chief science officer at the Center for Research and Innovation at the American College of Radiology.“This trial is not only about which technology works best, it is about how we can help individual women get what they need to avoid death from breast cancer.” “We should always base decisions about adopting new medical technologies on scientific evidence,” said Martin J.3D mammography or digital breast tomosynthesis is a new imaging technology that can identify small cancers not visible on traditional 2D mammography.If cancers are found when they are small, treatment options are generally less traumatic and the chance for a cure is greater.As many as 10% of women who have a routine screening mammogram will be asked to have additional mammographic views and possibly an ultrasound.The majority of these women - up to 80 percent - will experience what’s called a “false-positive” which means that an area that looked suspicious on their screening mammogram turned out, upon further testing, to be normal.Since current mammography relies on a 2D image, it has limitations because the breast is a 3-dimensional organ composed of different structures, such as blood vessels, milk ducts, fat, and ligaments.All of these structures can overlap and cause confusion when viewed as a 2-dimensional, flat image which is the leading reason why small breast cancers may be missed and normal tissue may appear abnormal.About the MAC.22 (TMIST) trial The Tomosynthesis Mammographic Imaging Screening Trial (TMIST), is the first randomized trial to compare two types of digital mammography for breast cancer screening: tomosynthesis (known as three-dimensional, or 3-D) and conventional (two-dimensional, or 2-D).Although 3-D mammography, is a newer technology it will likely detect more findings that require follow-up, it is also likely to lead to more procedures and treatments.
