WebbBoth Tc-99m HMPAO and Tc-99m ECD are labelled with technetium-99m (Tc-99m), a radioactive isotope with a relatively short half-life (approximately 6 hours) that is suitable for SPECT imaging. These imaging agents cross the blood-brain barrier and accumulate in brain cells, facilitating the measurement of rCBF. WebbUseful for calculating today's activity for any radioactive isotope. You may also back decay sources to find out the original activity (or for any date), knowing the current activity. If the isotope that you wish to decay is not on the drop down list, check the 'not listed' check-box and manually enter the isotope name and its half-life to ...
