I know you want a website but can I make a suggestion?
Ask a radiologist! Go down to the radiology department in whichever hospital youre placed at if you ever have free time and find a radiologist and ask him/her for help.
I hope I dont sound like a smart ass
Its just that I noticed that the rad departments are always empty of students (compared to other wards in the hospital) and Ive yet to meet a radiologist who wasnt eager to help. I guess its their only contact with the outside world
hehe jokes.
One on one teaching is much better than just looking at a web site, if ya know what I mean. Radiologists are great teachers and dont make you feel dumb for not knowing anything (compared to surgeons and physicians) 😀
