Subspecialization in pediatric radiology.

Within radiology there is an increasing trend towards specialization in North America [1]. Although some radiologists still consider themselves as generalists, every radiologist has eliminated some aspect of imaging from his repertoire [2]. Within some specialty areas of radiology further subspecialization is beginning to take place. This subspecialization is being affected by conflicting forces, some of which are pushing us towards increased subspecialization in our daily clinical work, while other forces are inhibiting such subspecialization.
