Technetium (99m Tc) sestamibi is a lipophilic cation which, when injected intravenously into a patient, distributes in the myocardium proportionally to the myocardial blood flow. Single photon emission computed tomography imaging of the heart is performed using a gamma camera to detect the gamma rays emitted by the technetium-99m as it decays.
Technetium-99m (Tc-99m) can be readily detected in the body by medical equipment because it emits 140.5 keV gamma rays (these are about the same wavelength as emitted by conventional X-ray diagnostic equipment), and its half-life for gamma emission is six hours (meaning 94% of it decays to 99 Tc in 24 hours). Besides, it emits virtually no beta ...
Technetium (99m Tc) mebrofenin is a diagnostic radiopharmaceutical used for imaging of the liver and the gallbladder. Under the brand name Choletec it is available from Bracco Diagnostic . Supplied as a sterile kit of mebrofenin and dehydrated stannous fluoride .
Technetium (99m Tc) pentetic acid, sold under the brand name Draximage DTPA among others, is a radiopharmaceutical medication used in nuclear medicine to image the brain, kidneys, or lungs. [1] It is given by intravenous injection or via aerosol spray. [ 1 ]
A nuclear pharmacist adds anywhere from 50 - 100 mCi of Na[99m TcO 4] to the reaction vial to make the final product, in the pH range of 3.8 to 8.0. After being allowed to react at room temperature for 15 minutes to ensure maximum labeling of the human albumin with 99m Tc, the kit can then be diluted with sterile normal saline as needed.
Technetium (99m Tc) mertiatide is a radiopharmaceutical medication used in nuclear medicine to image the kidneys. [1] It is a renal imaging agent that is given by intravenous injection. [1] It was approved for medical use in the United States in June 1990. [2]
Technetium-99 (99 Tc) is an isotope of technetium which decays with a half-life of 211,000 years to stable ruthenium-99, emitting beta particles, but no gamma rays. It is the most significant long-lived fission product of uranium fission, producing the largest fraction of the total long-lived radiation emissions of nuclear waste .
Technetium (99m Tc) tetrofosmin is a drug used in nuclear medicine cardiac imaging.It is sold under the brand name Myoview (GE Healthcare).The radioisotope, technetium-99m, is chelated by two 1,2-bis[di-(2-ethoxyethyl)phosphino]ethane ligands which belong to the group of diphosphines and which are referred to as tetrofosmin.
