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.
This began to cause a negative outlook on soda fountains as people saw them as âhabit-formingâ. Root beer first entered the marketplace in 1876 and the first cola-flavored beverage was introduced in 1881. Over 70 years later, the first âofficialâ diet soft drink was introduced in 1952, but others soon followed. In 1958, RC Cola introduced Diet RiteÂ®, the first nationally distributed diet soft drink.
