The perceived pro's and con's of radiology, or any specialty for that matter, are highly individualized. The best advice I could give you would be to spend some time in your institution's radiology department shadowing residents and attendings.
Here are some attributes of radiology that I personally enjoy:
-The best radiologists are profoundly knowledgeable in a vast swath of the medical terrain with some degree of expertise in virtually all fields of medicine, save perhaps dermatology and psychiatry. Though there are many proclaiming the death knell for general radiology given the spectacular breadth and depth of knowledge required, radiologists will continue to be among the smartest physicians out there. It's great to be trained in such a diversity of pathology. A good radiologist is an incredible asset to the treating physician.
-The technology that we get to interface with every day is amazing, approaching the realm of science fiction. It's easy to lose sight of the technical achievements embodied by an MR scanner or ultrasound probe, but virtually everything we do is dependent on some of the most sophisticated technologies on the planet.
-There is tremendous growth potential in the field. Aside from the double-digit year-over-year growth in clinical imaging, research and converging technologies are enabling an even more exciting future. Molecular imaging -- the ability to produce maps of physiologic activity on the protein and biochemical level -- is fast becoming a reality. Combined with advances in protein and gene-targeted therapy, radiology will remain on the razor's edge of medical innovation.
-There is great diversity to the opportunities available in radiology. You can do teleradiology from halfway around the world, work part-time, become a full-time interventionalist or live the purely outpatient lifestyle. Fellowship opportunities in radiology are plentiful (even overabundant) and assuming you're at a decent training program, relatively easily obtained.
And some of the things I enjoy less:
-The practice of radiology can become quickly monotonous and isolating. Dictating through queues of ICU plain films or a stack of mammograms alone in a dark room isn't a very exciting or pleasant experience.
-There have been significant reimbursement cuts to radiology, and there will be more coming down the pike. While cuts are being proposed (and in many instances, instituted) across the board, radiology is being unfairly targeted due to charges of over-utilization.
-Some select clinicians, especially surgeons, like to treat you like their imaging / biopsying bitch. You may often find yourself in uncomfortable ethical positions, approving studies or doing procedures of questionable medical validity to assuage the referring physician and maintain their business.
-I'm finding that radiology can be extremely stressful as a resident, especially in the chaos of the ED, where you are expected to interpret complex imaging studies at breakneck speed despite limited experience, making diagnostic decisions that are often central to patient outcomes.
