Iodine 123 Research Paper

contraindication of contrast media In the radiation they are using many tints , e.g. barium also We are using in the nuclear medicine and it’s called radiopharmaceuticals such as Carbon-11 , Chromium-51 , Fluorine-18FDG , Gallium-87 , Gallium-86 citrate , Technetium-99 , Iodine-123 and Iodine-131 . there are all these different uses pigments have benefits and harm . Firstly , we will talk about Iodine-123 is used to diagnoses the patients . It use for routine scan the time of imaging 4-6 or 24 hours and dosage 100-400 microCi po , Also we can use for thyroid cancer the time of imaging 4-6 or 24 hours and dosage 1.5 mCi po . The photon energy of iodine-123 is 159 keV . The half life is 13 hours . It has many advantages in the medical industry and use easy to detect defects in thyroid and half life fits human beings and not attacking cells within the body and easy to use in “SPECT”. In other hand it has also disadvantage at remove excess iodine-123 can be difficult and it is advisable to use an antiseptic and removing physical contamination that may be ineffective and …show more content…
technetium-99m is an isotope of the artificially and it has many characteristics for nuclear medicine scan the first one it has a half-life of six hours and it decay by process called “ isomeric ” and emit low energy of gamma rays and this helps to easily exit the body and can be detected accurately also emit beta rays but without high energy radiation dose to the patient is low . It has different number of compounds created for various structures such as CNS imaging it use Tc-99 ECD , bone imaging it use Tc-99 MDP , renal imaging it use Tc-99 MAG3 , parathyroid imaging it use Tc-99m sestamibi , lung ventilation imaging and bronchial clearance it use Tc-99 DTPA ( aerosol ) and to differentiate between malignant and benign use Tc-99m MIBI
