Examples

“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.”
