Besides the gigantic Tc-99m market‚ florbetapir F 18 and F18-FDG are gaining popularity through their applications for Alzheimer’s disease and diagnosis of brain tumors. Nihon Medi Physics‚ Covidien‚ Fujifilm‚ and ANSTO contributed more than 75 % to the APAC radiopharmaceuticals market in 2012. It is estimated that Tc-99m diagnostic procedures are expected to increase by more than 30% in the developing markets of the Asia-Pacific

Radiotherapy: a method to destroy cancer cells by irradiation with radioactive isotopes or X-rays. a.

The radioisotope used in about 80 percent of nuclear diagnostic procedures is Tc-99m. Tc-99m is used to diagnose osteoporosis‚ a condition caused by calcium deficiency in older people‚ especially women. Radioactive chemical tracers emitting gamma rays or positrons can provide diagnostic information about a person’s internal anatomy and

Lab 3: Newton’s Second Law: The Atwood Machine Introduction: In the study of physics a lot of the basics were put in place by Isaac Newton. Out of the 3 laws of motion he had declared the second law states that force equals mass times acceleration (F=ma). The Atwood machine is a machine that has a pulley in the air and a string running through the pulley‚ some kind of mass is suspended by each end of the string. When the suspended masses are unequal‚ the system will accelerate towards the direction

I found out from this experiment that half-life means just what it sounds like. After each cycle of half-life‚ the number of coins left was about half. Each coin represents an atom and just like in nature the half-life of decay is half depending what the element’s half-life is. If each of the scatter test was 10 years‚ the element we are testing would have a half-life of 10 years. The amount of time for a half-life depends on the elements‚ and how tightly the atoms are packed together. Some other

Nuclear Medicine Nuclear medicine has been around for more than 50 years now and stems from the discovery of x-rays and artificial radioactivity. In 1946‚ nuclear medicine made a monumental breakthrough when radioactive iodine led to the complete disappearance of cancer in a patient’s thyroid. Nuclear medicine became widely used in the 1950’s to measure the function of the thyroid‚ to diagnose thyroid disease‚ and for the treatment of patients with hyperthyroidism. By the 1970’s nuclear medicine
