How many years is the direct IR pathway? How would one go about looking up these programs on Freida or CareerMD? After completion of the program, would one be competent enough in Diagnostic to exclusively work in it should one desire to do so?
6 years, so it is equal in duration to internship + residency + fellowship. In a DIRECT pathway, you would get 24 months of IR. Thats 6-8 months more than in a residency + fellowship. Caveat emptor, this extra experience comes at the expense of the other subspecialty rotations, but hopefully you will get at least the minimum to pass the radiology boards. BTW, the only officially required rotation in Dx radiology is 4 months of nuclear medicine, there is no officially mandated minimum number of months for Neuro, Peds, etc. Potentially you may get a single month of Neuro or Peds during your tenure.
Furthermore, the direct pathway is NOT a back door into radiology. At the programs I know of, you are ranked with the other diagnostic residents and if you match, one of the IR fellowship slots will be allocated for your year. In other words you are in the same applicant pool as the diagnostic candidates, there is no a separate applicant pool for the DIRECT pathway.
Moreover, you will likely complete the fellow year before PGY6 (when you would normally complete a fellowship year). If you want to be a radiologist through the DIRECT pathway, you WILL finish the IR year. You can't just drop the IR portion and proceed like a conventional diagnostic resident.
I think the DIRECT pathway is definitely a step in the right direction. If Interventional radiologists want to stay competitive with cardiologists and vascular surgeons, than they MUST become more clinically-oriented. If you are truly interested in IR, get as much clinical training as you can your intern year. Do a surgery or IM prelim rather than transitional.
As I alluded to in previous posts, academic radiology is constantly in flux. Really strong IR divisions can unexpectedly falter and vice versa in the span of a few years, IE west coast programs. If you are confident that IR at your program will be strong when you are to become a fellow (places like UVA, NW, or JH) then consider the DIRECT pathway.
