As a nurse practitioner the question of do an MRI vs not is a daily issue. I agree that cost is much less of an issue for the Brewers than it is for my patients. But the problem with all imaging is, when there is significant swelling or inflammation in the area the scan could be less receptive to damage and thus pointless. I do not know if this is the case in Gamels situation or not but it is a possible explanation. Ultimately, injuries in athletes is a very difficult situation. I know the pressure we get in primary care to get/keep these high school and college athletes on the field. I cannot imagine what it is like in the pros.
