Myoview- $325/vial
Cardiolite $350/vial
Myoview and Cardiolite are the only two options available, making it an oligopoly. Price competition is not desirable because it would lead to reduced revenue for both producers •According to the Journal of the American College of Cardiology Cardiolite demonstrates greater myocardial perfusion defect, reversibility, extent and severity then Myoview. •This may explain why Cardiolite is $25 more than Myoview •Other gamma ray emitting radionuclides are priced much lower than these two because they use more commonly more accessible chemical elements like Iodine and Flourine and have a much longer half life


For many years Thallium-201 was the only agent available •Cardiolite is only became available at the beginning of this decade. •Myoview was even more recently approved for use in both Canada and the United States •Cardiolite and Myoview both proved to be more proficient then Thallium-201 and have a significantly shorter half life which allows for higher injectable doses and offers a significant advantage over Thallium with regard to image quality •Thallium was the industry standard, now it is Cardiolite and Myoview

A gamma camera is the device used in nuclear medicine, to view and analyse images of the human body of the distribution of medically injected gamma ray emitting radionuclides (Cardiolite and Myoview).

Technetium-99m is used in 20 million diagnostic nuclear medical procedures every year. Approximately 85 percent of diagnostic imaging procedures in nuclear medicine use this isotope. Technetium-99m is made from the synthetic substance Molybdenum-99 which is a by-product of nuclear fission. It is because of its parent nuclide, that Technetium-99m is so suitable to modern medicine. Molybdenum-99 has a half-life of approximately 66 hours, and decays to Tc-99m, a negative beta, and an antineutrino. This is a useful life since, once this product (molybdenum-99) is...
