I know of one individual who completed neurology, radiology, and 2 years of interventional neuroradiology. This INR guy had about 12 job offers after he was done, and is now in practice as a neuro-interventionalist, occasionally reading basic radiology studies (e.g. x-rays) and even has admitting priveleges at one hospital, though he does not admit patients himself often.
I asked him what advantages neurology offers him, and he says that it brings respect in terms of his clinical skills. Radiology of course gives him something to do to make money without having to work very hard.
He liked the path he took, but suggested that doing INR through neurology after doing fellowships in vascular and/or neurocritical care might be better for those interested in remaining clinical, while INR via radiology only is better for those not interested in taking care of their patients outside of the angio-suite.
