Researchers say digital breast cancer tomosynthesis, a 3D imaging technology, is more accurate than 2D digital techniques at detecting breast cancer. 카지노사이트
They add that 3D technology also generates fewer false positives. Experts say that 3D projections are more expensive. But increasingly being used in the medical field.
There is evidence that more advanced screening technologies may be more effective in detecting breast cancer. A study published today in the journal Radiology reports that digital breast tomosynthesis (DBT), a 3D imaging technique, provides better screening results than standard digital mammography. If this sounds a little familiar… that’s because it is.
However, the lead author of the study says what sets this study apart is that it examined a large and diverse population of women. “The results confirm what we’ve seen previously, but they’re impressive for their size,” said Dr. Emily Conant, professor of radiology and chief of the department of breast imaging at the University of Pennsylvania Hospital.
Breast Cancer Screening Details
Conant and colleagues collected data from five major health care systems in the United States. The group they studied consisted of more than a million women between the ages of 40 and 79 years. Women were screened with DBT digital mammography or 2D digital mammography. Only between January 2014 and December 2020.
Most women had at least two screenings. That means the researchers looked at over 2 million reviews. The cancer detection rate among participants screened with DBT was 5.3 per 1,000 screened. Compared to 4.5 per 1,000 screened with 2D digital mammography alone.
In addition to a higher cancer detection rate, researchers reported detecting fewer recalls and fewer false positives with DBT. Participants who were recalled had a higher cancer detection rate. “Are our memos more precise and detailed? Fewer false alarms? YES. Do we find more cancer with [DBT]? Yes, said Conant.
“And if we recommend doing a biopsy based on one of the interviews with asymptomatic women, do we always find more cancer cases? Yes.” “Part of the screening controversy stems from false positives. That’s because women are reminded of benign things, they even get biopsied for benign things,” Conant explained. “This is a very cost-effective way of detecting cancer early, before it becomes symptomatic.” 온라인카지노사이트
Dense Breast Tissue
Researchers say DBT is more effective because it captures more images of the breast from different angles. This is especially important for women with dense breast tissue. “The X-ray tube moves in an arc, taking many pictures at high speed while compressing,” Conant explained.
So you can flow through your breast. I wouldn’t know if there was something thickening it, she said.
“But [with DBT], when I can scroll and I can see from the inner surface of the breast to the outer surface, which is normal breast tissue, 3-D helps me see that you really don’t need any additional imaging.”
Should 3D screening be the standard of care?
Dr. Richard Reitherman, radiologist and medical director of breast imaging at Orange Coast Medical Center’s MemorialCareBreast Center in California, says he relies on 3D screening technology. “Yes, and most centers in the United StatesUse DBT because of its excellent performance,” she told Healthline.
However, it indicates that some patients may still need additional screening. The most sensitive test for breast cancer. But it is usually reserved for women who have increased risk factors. Such as a family history of breast or ovarian cancer. Conant says the equipment needed to perform DBT screening can be more expensive, but many mammography units across the country already have the capability to perform DBT screening. 바카라사이트
