Congrats on your Step 2 score. But I have to agree with the sentiments above. A high score doesn't make you competitive. A commitment to the field does that. Radiology interviews are one of the most stringent interviews out there. They will try to figure out if your true motivation is money, lifestyle, or love of the field. If you are just going for the lifestyle or money you will completely bomb the interview. Radiologists are one of the smartest physicians, they will study you and analyze you. That's what their training has sharpened. One of the cardinal traits of a radiologist is excellent observational skills. You will not fool a radiologist with your motive. Even if you do beat the system and match into radiology. You will regret it if your heart really isn't in to it. Let's see how much motivation you will have to study for the physics exam that 14% of the radiology residents flunk every year.
Also, Rads programs do not see Step 2 as a 2nd chance to "prove" yourself. The reason Rads programs focus so much on Step 1 is because there has been extensive research that shows a correlation between the written and oral boards to Step 1 success. There is NO correlation to Step 2 and Radiology Boards. One reason is because the amount of information during the 1st two years of radiology has about the same learning curve as the amount of information you must master the 1st two years of medical school. The volume is enormous. Also, there is quite a bit of basic science in radiology you have to have strong knowledge of anatomy, neuroanatomy, pathology, physiology etc.
Last point is this. Diagnostic Radiology is a 5 year program, and 75% of the residents go on to do a fellowship. Are you willing to read books for the next 5 years (or 7) of your life at night? No other specialty requires as much reading as radiology. If you chase lifestyle or money, you will be miserable reading "boring" books. That means you will be miserable for a half a decade. Even worse you will be absolutely miserable as a radiologist because you don't really have a passion for the field. And once you become miserable you will just go through the motions of being a radiologist and make misses, and might even succumb to depression because you might come to the conclusion that you spent about 13 years (4UG+4Med+5Rad Residency) of your life to train for something you don't like.
Furthermore, it is foolish to pursue lifestyle and/or money to go into radiology because those things are transient. Lifestyle is gone because of the advent of 64 slice CTs and 24 hour CT coverage. Reimbursement for images will be slashed. The government has already cracked down on outpatient radiology practices by cutting CT reimbursement by 40%. Take a look at the deficit reduction act that has passed and will go in effect in 2007.
With all that said, you have a good chance to match somewhere if you polish your marketing. Just remember the old adage. "Be careful what you wish for because it might come true". In this case, you will have invested over 13 years of your life for an academic radiology career that will pay (due to reimbursement cuts) the same amount as a ED physician with only 3 years of residency.
The ball is in your court. Let's see if you are willing to gamble your future on a specialty that is in transition with a downturn in salary.
