I am going through this process now. I applied both IR and DR. I did away rotations in both IR and DR. I got plenty of interviews for both IR and DR. On my interview trail everyone but two people I met that was applying IR was also applying DR. As to the question of if doing IR and DR rotations will hurt you the answer is an emphatic no, it will help you actually and here is why. IR Residency is 5 years, 3 years meaning the majority of the time is spent doing DR so the fact that you have done DR rotations and have an idea of what DR is about will work in your favor because program faculty want to know that you won’t get in there program hate DR and want to switch to vascular surgery or something to that affect. Oh, and here is an obvious one, you have to be good at DR to be good at IR ask any good IR doc and they will tell you that. As far as discrimination applying to both programs, I only had one program that choose to only interview me for IR and not their DR program, so I am not going to say it won’t happen but the vast majority won’t give a ****. Listen, and this goes to whatever your applying to, your application has to tell a consistent story for example, you first became interested in rads during your preclinical years when you got some small exposer to imaging and explain what interested you about it, then during your third year one of your pts needed an IR procedure and you went and watched then you started shadowing IR, possibly research in IR, Possible SIR involvement, 4th year electives in both IR and DR from which you did so well you got great letters of rec, this is a consistent story and is what PDs look for in applications. Now what’s say you don’t think you have a chance at this X IR spot but you think for whatever reason you have a chance at X DR spot so you only apply to there DR program and not there IR program the PD will see all your IR interests in your app and will wonder why you did not apply to IR as well and it will be a red flag where is if you would have applied to both the DR PD would likely not seen this as a red flag and invited you for an interview because they have ESIR.
