NEW ORLEANS, June 16 Naviscan PET Systems(R), a companyspecializing in organ-specific high resolution PET scanners, announced todayat the Society of Nuclear Medicine's Annual Meeting, new clinical data usingthe PEM Flex scanner in breast cancer management. The PEM Flex(TM) Solo II isa commercially available, FDA cleared scanner that utilizes PET technology forthe breast application known as positron emission mammography, PEM.

Results presented from an independent study of 136 patients comparing theaccuracy of PEM and MRI in the pre-surgical planning of breast cancer patientsindicated the PEM technology is more sensitive than MRI in detecting thesmallest cancers. PEM demonstrated 91% sensitivity in ductal carcinoma insitu (DCIS) compared to 83% with MRI and better sensitivity in cancers lessthan 5 millimeters in size. PEM also detected a 2 millimeter DCIS case shownto be negative on MRI.

"In our research, PEM accurately detected and characterized the smallestand most difficult to see cancers -- specifically DCIS, which is oftenimpossible to see with other imaging modalities," said Kathy Schilling, M.D.and medical director of the Center for Breast Care in Boca Raton, Florida, whohas been studying PEM for more than two years. "The ability to image anddiagnose these early stage cancers provides the potential for cure and willsignificantly impact breast cancer management." Dr. Schilling has been usingthe PEM Flex scanner in her practice as a tool for evaluating additional andunsuspected disease in the breast and compares these findings with that ofMRI. She is also a site principal investigator in a 400 patient, multi-centerclinical trial comparing PEM and MRI in breast cancer patients to be completedin 2008.
