The preliminary data show promising results for PEM in accurate lymph node assessment.  PEM demonstrates 88% sensitivity with a negative predictive value of 91% in assessment of ALN status in patients with breast cancer.  The data show improved lesion detectability and decrease in background activity.

"Our study provides additional compelling evidence that PEM can play an important role in axillary staging, perhaps with more sensitivity than ultrasound or MRI," stated Dr. Daniel Appelbaum, Associate Professor of Radiology from The University of Chicago Medical Center.  "Furthermore, these findings, in conjunction with PEM's more extensively documented role in evaluating the breasts themselves as well as whole body PET's excellent whole body staging, paves the way for a complete breast cancer work-up??”primary tumor, regional and distant metastases--with one FDG dose."

Naviscan plans to distribute its PEM scanner in Europe in Q2 2011.
