I think this is exactly the biggest issue. It's cardiologists taking over cardiac imaging, neurologists over neurorads, etc...
It's already happening in the interventional field, these specialties are trying to take over rads. In fact, cardiologists already took a big piece. The advantage specialties like cardio and neuro have is that they have their own patients. So I think they're the real threat.
YES, but its a dynamic process. IR developed and 'took' what was not originally in their 'turf'.
IE angioplasty and stenting developed by IR took away business from Vascular surgeons who then only knew how to do by pass and do open thrombolectomies.
There used to be a diagnostic component to general surgery. Remember before CT, and CT guided biopsies, diagnosis of cancer was made via open biopsies. The number of Ex-laps performed has drastically decreased. The biopsy / diagnostic aspect of medicine has fallen into the realm of radiology.
The same is true for abdominal abcess drainages.
Vascular access is a relatively easy and lucrative aspect of medicine once dominated by vascular surgery, which is now more easily done with image guidance.
Pneumoencephalography and cerebral angiography was once in the domain of neurosurgeons, but with the advent of crosssectional neuroimaging those modalites fell into the realm of neuroradiology.
Depending on how you look at it, the first 20 years of IRs history, IR had stolen lots of turf from other specialties.
What looks like 'loss' of turf from IR is the regain of turf from IR by other specialties.
Meanwhile turf is gained by IR as we speak. UFE is a great procedure which directly competes with myomectomy and hysterectomy for fibroids. In the field of oncology Chemoembolization and radioembolization as well as other loco-regional image guided ablations are giving viable and EFFECTIVE alternatives to the standbys of surgery (not everyone is a candidate), chemo (systemic side effects), radiation.
Maintanence of AV shunts and grafts mean that vascular surgeons are putting in less shunts and grafts than before.
Hardly anyone does surgical splenorenal shunts for portal hypertension anymore thanks to TIPS.
Yes IR is under attack, but in spite of this, IR continues to evolve and stay ahead of the curve, and according to salary figures from recent threads -- is doing this quite well I might add!
