Brazil : A gun loaded explodes near a MRI machine killing a man

A Brazil­ian man died last month when his hand­gun explod­ed near a work­ing MRI machine, shoot­ing him in the abdomen.

The 40-year-old lawyer and gun-own­ing advo­cate said he was not allowed to use the weapon despite ver­bal and writ­ten demands to remove all met­al objects before going to the scan­ner room with his moth­er. It seems to have con­tin­ued to have

Lean­dro Math­ias de Novaes took his moth­er to Lab­o­ra­to­rio Cura in São Paulo, Brazil on Jan­u­ary 16 for an MRI.

Clin­i­cal staff report­ed­ly ordered De Novaes and his moth­er to keep met­al items out­side the scan­ner room, as per nor­mal procedure.

“We would like to empha­size that the Cura team fol­lowed stan­dard acci­dent pre­ven­tion pro­to­cols at all units,” a spokesper­son for the cen­ter told The Telegraph.

“Patients and their com­pan­ions were prop­er­ly instruct­ed to enter the exam­i­na­tion room and warned against removal of any met­al objects.”

The rea­son for this sim­ple act is very sim­ple. MRI uses mag­net­ic fields of 1.5 to 3.0 Tes­la (some­times high­er) to image the human body by ori­ent­ing the pro­tons of water mol­e­cules in rough­ly the same direction.

A low-ener­gy elec­tro­mag­net­ic pulse caus­es the par­ti­cles to move and, depend­ing on the sur­round­ing mat­ter, take more or less time to return to their orig­i­nal loca­tions. By inter­pret­ing the con­trast of this pro­ton motion, we can get a detailed pic­ture of the interior.

To find out how strong a mag­net­ic field is, you can mea­sure a few thou­sandths of a tes­la with a refrig­er­a­tor mag­net. Some pow­er­ful rare earth mag­nets have strengths as high as 1 Tesla.

So 3 to 7 tes­la is not rum­bling. How­ev­er, large fer­ro­mag­nets (objects made of mate­ri­als that react rel­a­tive­ly uni­form­ly in strong mag­net­ic fields) can be suf­fi­cient­ly impacted.

In 2001, an MRI inci­dent caused a child to suf­fer fatal head injuries when a met­al oxy­gen cylin­der detached across the room.

For exam­ple, in the case of small objects such as gem­stones, strong mag­net­ic fields can con­duct cur­rents through the mate­r­i­al and con­duct enough heat to cause local­ized burns.

We may nev­er know exact­ly what hap­pened in the Novaes case. A gun hid­den in his waist belt explod­ed when the machine was acti­vat­ed, inflict­ing trag­ic injuries that cost him his life a few weeks lat­er at the Saint Louis Morumbi hospital.

An advo­cate for gun own­er­ship and with thou­sands of fol­low­ers on his social media accounts, it was clear that De Novaes was no stranger to guns. Police records show he had a cell­phone license and a reg­is­tered gun.

I don’t know if he was com­pla­cent or for­get­ful, but it’s an inci­dent that makes you real­ize the incom­pat­i­bil­i­ty of MRI and guns, and it’s noth­ing new.

Accord­ing to an arti­cle in the Amer­i­can Jour­nal of Roentgenol­o­gy in 2002, an off-duty police offi­cer vis­it­ed an out­pa­tient imag­ing cen­ter in New York State, and a patient brought a firearm into the scan room due to mis­com­mu­ni­ca­tion. bottom.

When he placed the gun on a cab­i­net a meter away from the machine, it slipped out of his hand, into the scan­ner, and was thrown at the wall.

Mean­while, in 2013, while inves­ti­gat­ing a call to a late-night rob­bery at an MRI clin­ic in Illi­nois, a police offi­cer on duty had his gun removed from his hand and left in the machine. has occurred.

In 2018, a man injured his leg at a Long Island clin­ic when a firearm in his pock­et caught fire as he entered the MRI room.

Although short, this list of dan­ger­ous MRI episodes will grow as gun own­er­ship in the Unit­ed States ris­es, poten­tial­ly caus­ing more injuries and deaths. Hun­dreds of peo­ple die each year in the Unit­ed States from unin­ten­tion­al firearm use.
