Radiology is no longer a lifestyle field. Granted we don't round on patients, so theres less clinical BS and paperwork to deal with. Sure we work 7 or 8 AM to 5 PM and call might not be as frequent as some of the clinicians. But when we are working you are reading non-stop from 8-5 with a short break for lunch. There is Virtually no down time, its balls to the wall all day, day in and day out. You just have to draw a line and stop reading somewhere at 5PM. There are often times plenty of studies to be read by the on-call rads that are left over from the work day. On call we read non-stop, no down time till 8 am, then we stay after to 'read out' with the attendings. Even the neurosurg residents have time to get a short nap in when they are on call.
When you go home at 5pm you still have to read a good amount. Radiology encompasses an unbelievable volume of information that must be learned during the 4 years of radiology that you can't possibly learn by simply paying attention on-the-job.
Let me put this in perspective... I know of a program in which 5 of the 6 graduating seniors got/were getting divorced by the end of the residency. This is something you might expect from a general surgery residency.
As far as earnings, they are at a peak and can only go down as the federal govt will slash reimbursement for x-ray studies in an attempt to curb rising health care costs. Part of the problem is clinicians ordering too many not-useful tests, or blatantly self referring exams to their own imaging equipment help their income -- but that is an entirely different issue for a different thread. What the government decides to pay thru medicare sets the tone for what insurance companies are willing to reimburse.
Outsourcing is the least of our worries at the moment. If you really like radiology, then do it. Just realize radiology is no longer the cush job that it used to be. You will work your ass off and earn every penny you make, and there are turf issues now more than ever.
If you are any good, you will never go hungry and will still have a job that pays better than what 99% of the rest of the people in this country make and better than what 99.99% of the rest of the world makes. In 1996, the bottom dropped out of the radiology job market, and those that decided to stick to their guns and pursue a rads residency (they either really loved radiology, or had to settle for radiology) were suprised with a booming job market (probably the best ever) when they finished.
Thats my 2cents. Good luck.
