==> What Benoit meant is that if the user writes :
f->SetFileName("foo.dcm");
f->Load();
                               
<-------------------------------------------  User modifies the "Patient

f->Load(); // The header is *not* reloaded

JPRx

(*) User would better to go and see a medical doctor, not to play with 
medical images ;-)
