“He points to a new scanner, called the positron-emission tomography (PET), which by detecting biochemical changes in the brain could aid in diagnosis.”

“New imaging advances have greatly improved the ability of doctors to visualize what is happening inside the body. These include the CAT and PET (positron-emission tomography) scanners, soundwaves to study the heart (echocardiography) and improved radioisotopes and radiation-sensitive cameras to spot tumors, watch the blood flow or the heart beating.”

“The brain is only part of the PET story. Positron-emission tomography—PET’s formal name—can be used to study the workings of cells throughout the body.”

“MRI tests and positron-emission tomography didn’t exist in William James’s day, but today, it’s quite possible to see which parts of the brain we use for what functions.”

“[Bennet] Omalu’s experimental breakthrough – along with UCLA researchers – uses positron-emission tomography (PET scan) and a radioactive “tracer” called FDDNP to bind to tau proteins in the brain.”

“Positron-emission tomography is a nuclear medicine imaging technique used to observe metabolic processes — of tissue or organisms — in the body to help diagnose disease.”

“He [Rob Beanlands] is a founding director of the National Cardiac PET Centre, the first facility in Canada dedicated to the use of PET (positron-emission tomography) as a non-invasive cardiac diagnostic tool.”
