18F-FDG is rarely used to image tumors in the kidney, prostate, or bladder because: - FDG is actively excreted in the urine, obscuring tumor uptake in these organs A patient who is maintained on a ventilator is transported to the nuclear medicine department. In the transfer process, it is necessary for the nuclear medicine technologist to compress the Ambu-bag being used to sustain the patient's breathing during transport. The rate for compression of the bag should be approximately: - Once...

Where are x-rays made? - in the electron shell structure of an atom What is Bremsstrahlung radiation? - energetic electrons pass very near the nucleus of an atom. The strong forces of th positive charged atom causes the negatively charged electron to decelerate; the path of the electron is changed, and some of the kinetic energy of the electron is lost, and converted into x-rays what is characteristic x-ray radiation? - following the ionization of an atom that leaves an inner shell, outer ...
