Can Computer Programs Help Documents Find Breast Cancer?

Artificial intelligence tools can help radiologists discover breast cancer on Ultrasound New research suggests creating images and reducing the need for additional testing.

“Our study shows how artificial intelligence can help radiologists read the breast. Ultrasound Tests to reveal only those that show the true signs of breast cancer, And to avoid biopsy verification if it turns out to be benign. ” He is an assistant professor of radiology at NYU Grossman School of Medicine in New York City and a member of Perlmutter. cancer center.

About 13% of U.S. women are diagnosed breast cancer According to Americans, in their lifetime, including 300,000 this year cancer society.

New Study — Published Online in Journal on September 24th Nature Communications — Approximately 289,000 ultrasounds of 143,200 women treated at NYU Langone Hospital in New York City between 2012 and 2018 were included.

Researchers used these ultrasounds to create computer programs and trained them to find patterns in thousands of images.

And research found that it did a better job than a professional radiologist.

In a review of 663 breast exams, 10 radiologists had a 92% chance of giving accurate measurements. With the help of artificial intelligence (AI) models, their accuracy has improved to 96%. All diagnoses were reconfirmed against the results of tissue biopsy.

The study’s co-author, radiologist Dr. Linda Moy, suggested that AI tools could be game changers.

“If efforts to use machine learning as a triage tool for ultrasound research are successful, ultrasound may become a more effective tool in the breast. Cancer screening, Especially as an alternative MammographyAnd for those with dense breast tissue. ” She is a professor at New York University and a member of Perlmutter. cancer center.

“The future impact on improving women’s breast health can be serious,” Moy said in a NYU Langone news release.

Studies show that the tool improved the ability of radiologists to correctly identify illnesses by 37% when individually tested on more than 44,700 completed ultrasonography. We reduced the number of biopsies needed to identify suspicious tumors by 27%.

Ultrasound uses high frequency sound waves to create real-time images.Usually not used for breasts Cancer screening, It is cheaper, widely available in local clinics and does not expose patients radiation..Ultrasound does a better job in women with dense breast tissue Mammography Distinguishing packed but healthy cells from compact tumors.

Geras said it could be an alternative to mammography or as a follow-up diagnostic test.

However, ultrasound also has its drawbacks.

There are too many false positives anxiety And researchers pointed out unnecessary follow-up procedures. In past studies, cancer After biopsy, it turned out to be non-cancerous.

Researchers want to do Clinical trial In the current patient and the actual situation.They also want to refine their programs by including the additional risk of women due to family history and genetic variation. breast cancer..
