When I was a kid at school I managed to fracture my arm playing softball. After initially being miss-diagnosed by the school nurse I eventually ended up at hospital after two agonisingly painful days at home. Once there I was told I needed an x-ray and there came my first site of radiographers.
Radiographers can do two types of work. There are the therapeutic radiographers who treat people such as with radiotherapy when they have cancer. I however saw a diagnostic radiographer whose job it is diagnose through a variety of ways. In my case it was the good old x-ray but it can be a MRI scan, CT scan or an ultrasound depending on the situation.
With my situation where I may or may not have a fractured or broken arm it was the x-ray which was performed by a couple of radiographers; one of which was in training. They took a few x-rays with my arm in a variety of positions; not always easy when your in that level of pain. They did however get the job done.
So if you do ever have the misfortune to break a limp you will no doubt end up in hospital initially at the hands of radiographers who will assess the injury with x-rays giving you the treatment you then need for that particular problem.
