Cardiovascular magnetic resonance (CMR) imaging is a rapidly developing subspecialty with a clear training structure and good career prospects. Demand for CMR demand is growing rapidly, with an 85% increase in cases scanned nationally in only two years, and this demand is predicted to continue with the British Cardiovascular Society working group predicting a further trebling of demand in the five years from 2010 to 2015. The most recent British Junior Cardiology Association survey identified cardiovascular imaging as an increasing preference for subspecialty training with 22% of trainees choosing imaging in 2012 (up from 10% in 2005) and CMR as the preferred imaging modality (selected by 45%). However, it was highlighted that there were still difficulties in accessing training by around one third of trainees. We describe the common indications for CMR, what CMR training involves (including the accreditation process), as well as how trainees can access current training opportunities.
