How does an MRI camera win Indian men?

It is attracted by an MRI scanner resulting in death due to carrying a metal oxygen tank into the room.

Rajesh Maru died after being sucked in. Maru visited relatives at a hospital in Mumbai, India and was asked to hold a metal oxygen container . He entered the resonance room after the hospital staff had reported that the machine had been turned off, but the powerful magnet on the machine remained active and sucked the oxygen tank in Maru's hand, the Science yesterday reported.

The man can die by sucking liquid oxygen from destroyed containers . Police also said they had arrested two hospital staff involved in Maru's death for blaming charges.

Taking MRI pictures is quite safe for human tissue, but leaving metal close to the machine can be deadly. That's because the MRI machine works by using large magnets to create a magnetic field 1,000 times stronger than the magnetic field of a conventional fridge magnet . This magnetic field aligns positively charged protons in the nucleus of hydrogen at the soft tissue of the body. There are many hydrogen atoms in soft tissue, because soft tissue contains a lot of water (H ₂ O). Human skin is 64% water while the lung rate is 83%, according to an article published in 1945 in the Journal of Biochemistry.

Not only is the proton aligned, the MRI scanner also uses radio waves to transform the magnetic field, causing the proton to change direction. When the magnetic field is turned off, the proton turns in the normal direction, producing a radio signal that the MRI camera can measure. The rate at which protons return to their normal state differs depending on the tissue sample, so radio signals create different images of muscles, organs and other structures.

The strong magnetic field of the MRI scanner can be very dangerous if there is a metal object in the room while the machine is on, because the magnet can suck the metal towards it. The patient must remove all metal objects from the body before entering. Unscrewed metal organ transplant recipients cannot take magnetic resonance imaging.

Sometimes, metal objects brought into the room during the shooting caused a serious accident. In 2014, another Mumbai hospital technician got stuck for 4 hours in an MRI scanner after being sandwiched between a nurse carrying an oxygen tank and the machine. The technician cuts blood circulation from the waist down and temporarily paralyzes. He also suffered internal injuries and internal bleeding. In 2001, a 6-year-old boy named Michael Colombini died in Westchester, New York, USA, after being hit by an oxygen tank on the head during an MRI scan to examine a brain tumor.

The most common accident with an MRI scan is burns , according to a 2018 report by the non-profit organization The Joint Commission. When the metal remains in the patient's body or the tattoo contains metallic ink unnoticed, the magnetic field generated by the MRI can produce an electric current in the metal, causing tissue tissue burns.
