I think the answer is a definitive yes!!! In order to break the chains of dependence, you need the experience of making independent choices as an attending radiologist does. The only way to get that experience is call. There is an article called Call- A Rite of Passage that explains the reasons behind call and what is expected of a radiology resident at nighttime. Does any one think that they could be a good radiologist without the call experience? If so, explain!!
