MR Spectroscopy Helps Identify Cancerous Breast Tumors
Measuring the biochemical changes in breast tumors with magnetic resonance (MR) spectroscopy enables radiologists to more accurately distinguish benign tumors from cancerous ones, according to a study appearing in the August issue of the journal Radiology.
“Adding spectroscopy to breast MR examinations will not only reduce concern over possible missed cancers and unnecessary biopsy procedures, it may also improve the efficiency and quality of patient care,” said co-author Sina Meisamy, M.D., a postdoctoral fellow at the University of Minnesota Center for Magnetic Resonance Research in Minneapolis.
MR imaging of the breasts has a high rate of sensitivity (94 percent – 100 percent) for detecting tumors, but a variable rate of specificity (37 percent – 97 percent) for distinguishing malignant from benign tumors.

MR Spectroscopy Significantly Reduces Need For Breast Biopsy
In a study featured in the June issue of Radiology, researchers found that imaging suspicious breast lesions with magnetic resonance (MR) spectroscopy reduced the need for biopsy by 58 percent. The investigators, from Memorial Sloan-Kettering Cancer Center in New York, discovered that with the addition of MR spectroscopy to their breast MR imaging (MRI) protocol, 23 of 40 suspicious lesions could have been spared biopsy, and none of the resultant cancers would have been missed.
“All cancers in this study were identified with MR spectroscopy. There were no false-negative results,” said Lia Bartella, M.D., lead investigator and assistant professor in the Department of Breast Imaging at Memorial Sloan-Kettering. “With the addition of MR spectroscopy to our breast MRI exam, we found that the number of biopsies recommended on the basis of MRI findings decreased significantly. These results should encourage more women to take this potentially life-saving test.”

MR Spectroscopy Identifies Breast Cancer, Reduces Biopsies
Proton magnetic resonance spectroscopy (¹H MRS) used in conjunction with magnetic resonance imaging (MRI) can aid radiologists in diagnosing breast cancer while reducing the number of false-positive results and invasive biopsies, according to a study focusing on non-mass enhancing breast lesions.
“All of the cancers present in this study were identified with MR spectroscopy,” said the study’s lead author, Lia Bartella, M.D., director of breast imaging at Eastside Diagnostic Imaging in New York City.
