Radioactive substances unnecessary in new method for measuring brain glucose metabolism

Rather than administering radiolabeled glucose for exams, imagers give patients a small amount of a harmless glucose solution that is said to be equivalent to a can of a carbonated drink.

X-ray photon trajectory during the simulation phantom study from the side and top views. Due to scattering of the X-rays when they hit the lower end of the patient bed, exposure in mainly to the lower body of the interventional echocardiographer performing transesophageal echocardiography. The green lines are the scattered photon trajectories calculated by Monte Carlo simulation in the study.
