A computer-implemented method for monitoring progress of a radiopharmaceutical pumping procedure comprising: measuring and monitoring radiopharmaceutical activity of a radiopharmaceutical remaining in a portion of a disposable administration set used with a radiopharmaceutical fluid delivery device, wherein the measuring and monitoring are performed continuously during the radiopharmaceutical pumping procedure as the radiopharmaceutical is being pumped; and displaying the radiopharmaceutical activity of the radiopharmaceutical remaining in the portion of the disposable administration set, wherein the displaying is performed during the radiopharmaceutical pumping procedure as the radiopharmaceutical is being pumped; detecting whether the radiopharmaceutical activity of the radiopharmaceutical remaining in the portion of the disposable administration set differs from an expected value of radiopharmaceutical activity remaining in the portion of the disposable administration set at a given time during the radiopharmaceutical pumping procedure as the radiopharmaceutical is being pumped; determining that the radiopharmaceutical activity of the radiopharmaceutical remaining in the portion of the disposable administration set differs from the expected value of radiopharmaceutical activity remaining in the portion of the disposable administration set at the given time; and determining that a delivery issue has occurred during the radiopharmaceutical pumping procedure as the radiopharmaceutical is being pumped based on the determination that the radiopharmaceutical activity of the radiopharmaceutical remaining in the portion of the disposable administration set differs from the expected value. measuring and monitoring radiopharmaceutical activity of a radiopharmaceutical remaining in a portion of a disposable administration set used with a radiopharmaceutical fluid delivery device, wherein the measuring and monitoring are performed continuously during the radiopharmaceutical pumping procedure as the radiopharmaceutical is being pumped; and displaying the radiopharmaceutical activity of the radiopharmaceutical remaining in the portion of the disposable administration set, wherein the displaying is performed during the radiopharmaceutical pumping procedure as the radiopharmaceutical is being pumped; detecting whether the radiopharmaceutical activity of the radiopharmaceutical remaining in the portion of the disposable administration set differs from an expected value of radiopharmaceutical activity remaining in the portion of the disposable administration set at a given time during the radiopharmaceutical pumping procedure as the radiopharmaceutical is being pumped; determining that the radiopharmaceutical activity of the radiopharmaceutical remaining in the portion of the disposable administration set differs from the expected value of radiopharmaceutical activity remaining in the portion of the disposable administration set at the given time; and determining that a delivery issue has occurred during the radiopharmaceutical pumping procedure as the radiopharmaceutical is being pumped based on the determination that the radiopharmaceutical activity of the radiopharmaceutical remaining in the portion of the disposable administration set differs from the expected value.
