While mammograms are widely used to detect breast cancer, the use of MRI machines can now be used to further understand the effects of high saturated fatty acids in breast tissue in post-menopausal women.
Women at high risk of breast cancer often have routine MRI scans to try to detect any tumors early.
Developed at NYU Langone’s Department of Radiology, researchers used a new technique that helps to identify the relationship between breast cancer and the amount of fatty acids found in the tissue of a breast. These findings, they say, may one day lead to greater understanding of the underlying mechanisms behind breast cancer development and the role of fat as a factor in breast cancer diagnosis and progression.
“Our study offers the first evidence — seen in breast tissue — that high saturated fatty acids in the breast adipose tissue is associated with presence of breast cancer in postmenopausal women,” said senior author and investigator Sungheon G. Kim, Ph.D., associate professor in the Department of Radiology at NYU Langone and a researcher at the Center for Advanced Imaging, Innovation and Research.
While the relationship between cancer development and body mass index (BMI) fat has previously been studied, postmenopausal women were found to be at increased risk of breast cancer as their BMI increases. This new study suggests that the fat composition itself may also play a roll.
Kim and her colleagues devised an innovative method called gradient-echo spectroscopic imaging that provides information on various types of fatty acids based on a series of three-dimensional MRI images acquired over a period of five minutes. They also developed a new approach to MRI spectroscopic imaging, a type of MRI that provides information on the chemical composition of the tissue.
“There is a clear need for methods that can accurately measure fat composition of the breast tissue within a short scan time, and our study takes a first step towards meeting this critical gap,” said Kim.
An essential part of the more advanced imaging equipment would be having a precision lens designed and manufactured by UKA.
“Measuring breast fat composition only takes an extra five minutes, making this practical, new technique something that could easily be implemented in a clinical setting,” said study co-author Linda Moy, M.D., an associate professor in the Department of Radiology at NYU Langone and a member of its Laura and Isaac Perlmutter Cancer Center. “With further research, we could potentially use these findings to change how we look at breast cancer imaging.”
The population screened for this particular study was considered a high-risk group. They all were scheduled for a high-risk screening follow up, and as a result, more research is needed to determine the roll of fat composition in low-risk postmenopausal women, the authors say. It’s important to note that further research is needed to determine just how fatty acids may influence cancer development.
