ako je gavrankapetanovic rekao da moze, a radi MR na kosevu, ne vidim zasto bi trebalo uopste da brine...

ma vjerujem da se boji ali najbolje bi joj bilo da pita direktno ljude koji ce raditi MR...
oni znaju milion % smije li ili ne smije.... pa iskocice joj kicma na usta ako udje u magnetni tunel a ne bude smjela....

evo nesto sto bi ti moglo biti interesantno i definitvno njoj pomoci 
Because of its non-ferromagnetic nature and poor electrical conductivity, titanium and its alloys are useful for long term implants and surgical instruments intended for use in image-guided surgery. In particular, not only is titanium safe from movement from the magnetic field, but artifacts around the implant are less frequent and less severe than with more ferromagnetic materials e.g. stainless steel. Artifacts from metal frequently appear as regions of empty space around the implant - frequently called 'black-hole artifact' e.g. a 3mm titanium alloy coronary stent may appear as a 5mm diameter region of empty space on MRI, whereas around a stainless steel stent, the artifact may extend for 10-20 mm or more.
