The following passage, from an article on HealthImaging.com, caught my attention:

The honeymoon has ended for coronary CT angiography (CCTA) and the seven-year itch has commenced for some radiologists and cardiologists. They do not advocate replacing the technique though. Rather, they are asking if the requirements in training guidelines need a makeover to reduce variability and better maximize CCTA’s potential to improve patients’ clinical care and outcomes.

This brings up a good point: the credentialing criteria for performing and interpreting cardiac CT are now too low. I found the learning curve was long with a gradual slope. You need to be in a training and supervised environment with a fairly good case load for at least a year. It’s challenging, but performed well and interpreted with skill, it is a very valuable test which can save the healthcare system considerable cost – especially in low- to moderate-risk chest pain patients presenting to an emergency room.
