John P. Brockway, Ph.D., President and CEO of Memory Testing Corp., together with Angelina A. Tzacheva and Kayvan Najarian, Ph.D, University of North Carolina at Charlotte, NC, have had their manuscript accepted for publication in the Journal of Magnetic Resonance Imaging.

The title of the manuscript is:

Breast Cancer Detection in Gadolinium Enhanced MR Images by Static Region Descriptors and Neural Networks

This work describes a new method to detect breast cancer. The method requires the advanced use of Magnetic Resonance Imaging parameters combined with sophisticated computerized methods of examining images to detect and locate, as well as classify, breast cancer in women. These are women who have had negative results from mammographic tests as well as negative results from ultrasonography tests, but either they or their physician felt that there was suspicion to investigate further. Using T1 dynamic MRI series, and gadolinium enhanced images as well as spectral spatial analyses, breast tumors and their extent, that is, their margins, were located with five "static region descriptors" and the tumors were classified using neural networks which were trained on previous data sets. Very high sensitivity as well as high specificity for this method were reported. This means that tumors were not missed, nor were they classified as benign when they were malignant, or vice versa.
