Radiology is a hot, hot specialty these days. The advent of new technology and the shortage of radiologists today makes this a very promising field. One factor contributing to its popularity is the high salary. It is not uncommon for newly minted radiologists to be wooed with a 300K starting salary with several weeks of vacation. Most radiologist work a 9-5 job with weekend call being spread evenly among members of the group. As for patient contact, radiology is a field that is far, far away from the trenches of hands-on patient care. With the exception of interventional radiology, most radiologists have little patient contact. However, radiologists do have much contact with their referring doctors. Radiologists usually act as expert consultants to the doctors who order the images.
Rads is definitely a worthy field to think about, especially since it is projected to be a hot field for quite some more time. If you have the chance, it might be a good time to jump into the field although competition is becoming extremely stiff these days among medical students.
