The cotton gin was developed before the MRI, which was developed before steel, and steel was developed before the phonograph and DVD.
MRI is a technique using the phenomenon Nuclear Magnetic Resonance [NMR}. NMR was discovered by physicists,Felix Bloch and Edward M Purcell and won Nobel Prize for the same. MRI was later developed by the scientists, Paul Lanterbur and Peter Mansfield.
Steel was develped first in the 13th century.
The first MRI (Magnetic Resonance Imaging) scan in the United States was conducted in 1980. This groundbreaking technology was developed by Dr. Raymond Damadian, who performed the first human MRI scan on a patient in his New York laboratory. MRI rapidly evolved and became a vital tool in medical diagnostics throughout the 1980s and beyond.

As of recent estimates, India has approximately 8,000 to 10,000 MRI machines. The number has been increasing due to growing healthcare infrastructure and rising demand for diagnostic imaging services. However, this still represents a relatively low density of MRI machines per capita compared to many developed countries. Access to MRI services can vary significantly between urban and rural areas.
MRI (Magnetic Resonance Imaging) is not a direct product of the space program, but advancements in technology initially developed for space exploration contributed to its development. The principles of nuclear magnetic resonance (NMR), which underlie MRI, were discovered in the 1940s, and the technology was further refined in the following decades. Some innovations in electronics and imaging techniques that were enhanced during the space program did help improve medical imaging technologies, including MRI.
Before the development of MRI (Magnetic Resonance Imaging), several imaging techniques were used, primarily X-rays and CT (Computed Tomography) scans. X-rays, introduced in the late 19th century, allowed for the visualization of bone structures and certain soft tissues. CT scans, developed in the early 1970s, provided cross-sectional images of the body using X-ray technology. These earlier methods, while revolutionary, lacked the detailed soft tissue contrast that MRI offers.
If the MRI technologist positions you with your leg going into the magnet (the MRI machine) then your head would be out of it. Call the facility where you are scheduled to have the MRI and ask to speak with the MRI technologist and they can fully explain to you exactly how you will be positioned.

No. It is not a treatment it is a scan. An MRI is a Magnetic Resonance Imaging. MRI are used for imaging tissues.
