Calculations related to nuclear medicine
Instruction for the programs below is accessible here.
(1.)
Calculation of thyroid volumen on the basis of the lobes diameters
(2.)
Calculation of (radio)nuclide uptake (f.e. uptake of radioiodine in the thyroid)
(2a.)
Calculation of uptake of I131 in the thyroid (This program can be saved as a file and launched in another PC, a browser with HTML and
JavaScript is necessary; in Polish).
(3.)
Calculation of radioiodine dose (simplified)
(4.)
Kinetic modeling I. (effective halftime, maximal uptake and others, based on a series of measures)  for radionuclide therapy
(5.)
Kinetic modeling II. (effective halftime, maximal uptake and others, based on three measures)  for radionuclide therapy
(6.)
Calculation of dose of radioiodine or another radionuclide for treatment (modified Marinelliformula)
(7.)
Dosimetry of α and βradiation
(8.)
Dose rate and absorbed dose of γ radiation (in a distance from a point source)
Simplified calculation of the dose of iodine131 for treatment of benign thyroid disorders
This option has been developed mainly for the nuclear medicine doctors.
Calculations play a very important role in the nuclear medicine therapy,
however, the decision about the radiopharmaceutical apllied and its dose must be made by
the Doctor taking care of the Patient.
The Doctor makes the decision not only based on mathematical calculations, but also on his own knowledge and experience,
and takes also the full responsibility.
The dose of ^{131}I is calculated by a simplified formula: (400 * volumen [ml]) / uptake [%]. This method is only acceptable, when precise dosimetric data (multiple radioiodineuptake measurements) lack.
