WebPositron Emission (β + decay) and Electron Capture. In addition to the three major types of radioactive particles listed above, two additional less common types of emissions have been discovered. These include positron emission and electron capture. Positron emission (β + decay) is the emission of a positron from the nucleus. Oxygen-15 is an ... WebPositron emission tomographic (PET) perfusion imaging is an alternative to SPECT imaging. In most imaging laboratories, PET perfusion imaging is performed with Rb-82, a potassium analog that is transported intracellularly via the sarcolemma membrane. The tracer is eluted from a generator and directly infused into the patient.
