Non-Contrast HiSS MRI Performs Just as Well as Conventional Contrast-Enhanced MRI at Separating Benign and Malignant Breast Lesions

High spectral and spatial (HiSS) magnetic resonance imaging (MRI) — even when used without a contrast agent — matches the performance of conventional contrast-enhanced MRI at separating benign and malignant breast lesions, according to a study to be presented at the ARRS 2010 Annual Meeting in San Diego, CA. Contrast agents are used to enhance the image quality of an imaging exam.

HiSS MRI provides important functional and anatomical information that conventional MRI cannot. In addition, the image quality of HiSS MRI can be better than that of conventional MRI.

The study, performed at the University of Chicago in Chicago, IL, included 56 women who were imaged using both HiSS and conventional MRI. “Results showed that HiSS MRI (without contrast agents) performed just as well in the task of separating benign and malignant lesions as conventional MRI (with contrast agents),” said Milica Medved, MD, lead author of the study. “The accuracy of both tests was higher than 0.8,” she said.

“Currently, HiSS is still part of a research effort, and is not in routine clinical practice yet. We are hoping to change that — in fact, we are in the process of initiating a multi-center imaging trial which, if successful, would pave the way for routine clinical applications of HiSS,” said Medved.

The doctors diagnose the cancer and determine what kind it is by looking at a sample of the tumor under a microscope. This alone does not determine what treatment you can have. Before treatment, your doctors must determine if or how much the lung cancer has spread. This is called staging the cancer.
