Nuclear
medicine applies unsealed radionuclide & nuclear techniques to
diagnose & treat diseases.
What is isotope ?
Isotopes
are same element with different atomic weight due to different
neutron content.
What is
radionuclide ?
Radioactive
isotope of an element e.g., Iodine-131 is one of the radionuclide of
several isotopes of iodine
Radiopharmaceuticals used in Nuclear Medicine
The radionuclide
used in Nuclear Medicine are called radiopharmaceuticals as they are introduced
into the body. These radioactive
substances has to go through all the QC measures required by
pharmaceuticals along with additional QC measures▪ Chemical purity▪ Pyrogen free▪ Toxin free▪ Radiochemical
purity▪ Radionuclidic
purity▪ Dose limit
Is it safe?
Nuclear scan is very safe.
Non Invasive
There will be no reaction or side effects to the tracer injected.
Gamma rays are less hazardous to the patient's body than even the
X-rays, in the dose injected.
