for a much stricter sentence. Under the New Jersey law, the punishment for trafficking is a life sen tence. Following the presentation, UNWLA mem ber Christine Demidowich asked Mr. Romankow what individual citizens might do "to help stop this?" "Keep your ears and eyes opened," Mr. Romankow replied. "And report any suspicious be havior to the proper authorities." MEDICINE ON THE CUTTING EDGE: PET SCANNING POSITRON EMISSION TOMOGRAPHY by Ihor Magun, M.D., F.A.C.P. We live in an extraordinary era of medicine. Knowledge of disease states, progression of disease, and treatment has advanced so rapidly that research ers themselves are amazed. One of the exceptional advancements is PET scanning, which involves a camera that can produce powerful molecular images of the human body's biological function. This new imaging technology is readily available. The proce dure begins with an injection of a sugar that is la beled with a signal-emitting tracer. A glucose tracer is used because cancer cells and other indicated conditions use more glucose than normal cells. As these tracers circulate throughout the bloodstream, they collect in various body organs. A scanner re cords the signals emitted by the tracers. With the help of sophisticated computers, the pictures show biological causes of organ function and failure of organ systems in disease. The technology is so advanced that PET scans and CAT scans are combined into one scan ning system. What is amazing about this imaging modality is that a tumor seen on CAT scan can be confirmed by PET scan to be benign or malignant. Additionally, not only can PET scanning distinguish between benign and malignant tumors, it checks if the administered chemotherapy was successful. It can stage the cancer, look for metastatic disease and evaluate the following cancers: brain, breast, cervix, colon, esophagus, head and neck tumors, lung, lym phoma, melanoma, ovarian, pancreatic and prostate. PET scanning can evaluate coronary artery disease and can also help guide treatment choices for patients facing a choice of either cardiac trans plant or bypass surgery. PET scanning has also emerged as a diagnostic tool to confirm or differen tiate Alzheimer's disease. It can evaluate if a shak ing tremor is caused by Parkinson's disease. The most recent advancement has been seen in evalua tion of children with uncontrolled seizures. PET scanning can zero in on the diseased brain area, permitting a surgical removal of tissue with defini tive cure of the seizure in 80% of patients. Clearly we are in medical evolution. As medical professionals face their daily challenges, the extraordinary strides in imaging modalities is keep ing pace. We all can only marvel and benefit from these innovations. “Н АШ Е Ж ИТТЯ”, ЛИПЕНЬ-СЕРПЕНЬ 2005 17
