University of Rochester Reports SPY Accurately Detects Renal Tumors in the

TORONTO, May 22 /PRNewswire-FirstCall/ - Novadaq(R) Technologies Inc. (TSX: NDQ), a developer of real-time imaging and image guidance systems for use in the operating room, today announced that results of a clinical study of the SPY(R) Intra-operative Imaging System in urology was presented at the recent 2008 American Urological Association (AUA) conference in Orlando, Florida. The poster presentation, given by Dragan Golijanin, M.D., a urologist from the University of Rochester, was entitled Near Infrared Fluorescence (NIRF) of Intravenous Indocyanine Green (ICG) for Intra-operative Imaging of Renal Cortical Tumors: A Report on Completed Feasibility Study and was designated as the best poster in its scientific session.

During his moderated poster presentation, Dr. Golijanin reported that in a study of 20 patients, 17 of which underwent partial nephrectomies, all tumor and non-tumorous lesions were clearly delineated by intra-operative SPY imaging. SPY imaging resulted in all malignant lesions being clearly demarcated from normal tissue in the operating room and therefore the ability to perform partial nephrectomy and achieve clean tumor margins was greatly improved. The imaging data was compared with standard pathological outcomes of tissue margin sampling. Dr. Golijanin and his colleagues at the University of Rochester concluded that the use of SPY may allow urologists to diagnose additional lesions, decrease positive surgical margins rate, spare unnecessary resection of normal parenchyma, and preserve renal function.

"Successful partial nephrectomy for the treatment of renal cancer is predicated on the differentiation of lesions, removal of the entire tumor and achievement of negative surgical margins, all while maximizing preservation of normal kidney tissue," said Dr. Golijanin. "Our initial work in partial nephrectomy pa
