Imagine transporting a collection of clinical psychopaths across central London in shackles and handcuffs in rush hour, and in order to place each of them in an MRI scanner, you have to remove all metal objects, including shackles and handcuffs, and, as I learned, all body piercings.
Imaginem transportar um grupo de psicopatas clínicos pelo meio de Londres, com correntes e algemas, à hora de ponta. Para colocá-los num "scanner" MRI temos que retirar todos os objetos de metal, incluindo as correntes e as algemas e todos os "piercings" corporais.
