|
| After Dr. Harper's team injected the isotope, also known as a radiotracer or radionuclide, into a patient, it could be tracked through the bloodstream and eventually to the heart, liver and other organs. |
|
| The microspheres embolize the capillaries and emit beta radiation due to their Y-90 radionuclide, thereby irradiating the embolized tumor and potential liver parenchyma regions. |
|
| The LVEF information was available only for those patients who took at least one of three tests: catheterization, echocardiogram and radionuclide ventriculogram. |
|
| The experts are members of a multidisciplinary team of engineers and researchers specialised in vadose zone hydrology, hydrogeology, radionuclide chemistry, geochemistry, mass-transport phenomena and numerical modelling. |
