MRI (magnetic resonance imaging) is a noninvasive diagnostic test that takes detailed images of the soft tissues of the body.Unlike X-rays or CT, images are created by using a magnetic field, radio waves, and a computer.n MRI scan works by using a powerful magnet, radio waves, and a computer to create detailed images. Your body is made up of millions of hydrogen atoms (the human body is 80% water), which are magnetic.
The term âsoft drinkâ is derived from âsoda waterâ, dating as far back as 1798. Joseph Priestly invented carbonated water in 1767, when he first discovered a method of infusing water with carbon dioxide (CO2) by suspending a bowl of water over a vat of fermenting beer in a brewery in Leeds, England.
The first commercial beer available in cans began in 1935 in Richmond, Virginia. Not long after that, sodas, with their higher acidity and somewhat higher pressures, were available in cans. The key development for storing beverages in cans was the interior liner, typically plastic or sometimes a waxy substance, that helped to keep the product's flavor from being ruined by a chemical reaction with the metal.
